Should I write "PhD" or "Ph.D."?

Question pretty self-explanatory. Should the abbreviation of the Latin term philosophiae doctor be written as PhD (no periods) or Ph.D. (with periods)?

  • 1 You have a couple of correct answers below. Personally I avoid periods in abbreviations, so I would use PhD, just as I would say Washington DC using the postal code abbreviation DC rather than the historical abbreviation D.C. (District of Columbia). –  Wayne Commented May 17, 2011 at 12:38

Actually both are correct. I could easily find both on my NOAD, and there are plenty of pages on the net where you find it written as "PhD".

The OALD gives an interesting distinction, stating that Ph.D. is especially North American English.

Now, being a non-native speaker, I can only rely on official sources to state who uses what , but there's no doubt that both variants are used.

Lastly, I think there's really no point in distinguishing them as " Philosophiae Doctor " or " Doctor of Philosophy " because it's the same exact expression, although considering the abbreviation, the former is the correct and original long version, the latter is just the English translation.

  • 1 Collins English Dictionary shows a separate abbreviation if you want to specify the degree in English: "DPhil". (Also at dictionary.reference.com/browse/phd , just further down the page.) –  MT_Head Commented May 17, 2011 at 9:52
  • @MT_Head: Thanks for commenting. With "if you want to specify the degree in English" you mean "being unambiguous"? –  Alenanno Commented May 17, 2011 at 9:54
  • Indeed. To give an anecdotal example: in the company I used to work for, which was British, people didn't tend to use periods for abbreviations of degrees, e.g. MSc , PhD . I now work for an American company, where the convention is to use them, hence Ph.D. –  Steve Melnikoff Commented May 17, 2011 at 9:55
  • I see, I was thinking of that before honestly, since PhD (or PHD) can be other things too... Thanks for pointing it out! –  Alenanno Commented May 17, 2011 at 10:04
  • 6 @MT_Head DPhil is also what a PhD is called at Oxford. If you use DPhil then a BE speaker would assume you specifically mean Oxford. –  mgb Commented May 17, 2011 at 15:07

PhD and Ph.D. are both correct. Canadians tend to omit the periods and those from the U.S. tend to keep them. A reference grammar explains it like this:

2  abbreviations and acronyms 1  punctuation We usually write abbreviations without full stops in modern British English. Full stops (AmE ‘periods’) are normal in American English.   Mr (AmE Mr. ) = Mister (not usually written in full)   kg (AmE kg. ) = kilogram  […]

I tend to use both 'PhD' and 'Ph.D'. A DPhil is awarded at both Oxford Uni and Sussex Uni in England. All others award PhDs to my knowledge.

It bugs me when people use 'Dr' before their name and then also state the award following it. I feel it should be one or the other.

  • 1 @hBy2Py : Ha! That's an example of the ironically named RAS syndrome (Redundant Acronym Syndrome syndrome). According to Wikipedia the term was coined in 2001 in a light-hearted column in New Scientist, though I haven't a reference for the original article. On the original question, during my lifetime (started in the 1950s) in the UK there has been a slow but steady move to reduce the use of punctuation and capitalisation in print. This has been driven in part by the newspaper industry, though I can't give any source other than the say-so of journalist friends. –  Duckspindle Commented Sep 3, 2022 at 12:17

As many noted, both are accepted, so it is a matter of convention and taste.

The important is to be consistent with the other abbreviations you use throughout your text. Compare:

  • I got a Ph.D. in A.I. at U.C.L.A in the U.S.
  • I got a PhD in AI at UCLA in the US.

My personal preference goes for omitting periods, given that this is an abbreviation, following the Guardian style guide :

Do not use full points in abbreviations, or spaces between initials, including those in proper names

Matifou's user avatar

I remember discussing this with a trained secretary a long time ago. We eventually decided that the use of camel case (starting each abbreviated word in upper case) removes the need for the periods when abbreviating titles. However, when an abbreviation is relatively new or used in an unusual context, the periods help to avoid ambiguity.

For my own use, the overriding consideration is 'house style'. It is more important for a document to be internally consistent, to avoid confusion.

Bobble's user avatar

  • Bobble's "house style" consideration typically applies not just to a single document but also, as the name implies, to all documents emanating from the same "house". For example, my academic discipline (linguistics) traditionally employs the no-periods convention for all titles (not only PhD, MA, and BA but also Mr, Dr, and Prof), while the style enforcer at my academic institution (an American university) insists that I sprinkle periods around (for a total of 9 in my 6 examples). –  H Stephen Straight Commented Feb 12, 2013 at 22:32

The most common I have seen are:

I have rarely come across a Ph.D. (with two periods).

How to use the PhD title and all the little doctorate “rules”… use ph.d etc the correct way.

There are many conventions in the academic world that can make it difficult to navigate the philosophiae doctor title. The PhD title is awarded to those who have completed a doctoral degree but, not many people know how to use it once they have it.

It’s best to use PhD not Ph.D in most cases!

This article will go through everything you need to know about using the PhD title and when you can start using it.

The “rules” are relatively simple and can be broken as they are not officially set in stone – other than when you can officially call yourself a doctor.

There is no one correct answer but it may be misleading if you use the PhD title incorrectly. Here are the recommendations for effective communication for a PhD graduate.

It very much depends on the setting. Here are some examples of how I would use both the titles awarded to me after my PhD degree.

SituationPreferred titles
Full formal university businessDr Andrew Stapleton Ph.D, MChem
University emailsDr Andy Stapleton
Speaking to a primary school classDr Andy
Emails to students I am lecturingDr Stapleton
How I wish to be called while teaching university classesAndy

How do you Write PhD correctly after a name? Is it ph d or phd and ph.d? Abbreviation explained

It can be confusing to know exactly how to write PhD after your name as a person with a doctoral degree. Which bits are capitalised for a person with a doctoral degree? Is there a ‘.’ In the middle?

When writing a name with a PhD after it, the correct way to do so is to use “PhD” or “Ph.D. or Ph D”

Depending on the preference of the individual, either form can be used.

However, if the individual has a business card that states their degree in full, then the more formal “Doctor of Philosophy” should be used.

It is important to note that using “PhD” without any periods is incorrect; this abbreviation should only be used in informal contexts such as emails or text messages. I tend to use PhD in my YouTube videos and some people have pointed out that this is incorrect…

Following the individual’s preferred format will ensure that their name and credentials are properly represented.

Should you use Dr as well as PhD?

Some people like to use Dr and PhD in their official titles. There are a couple of important points that you need to know about markers and academic titles.

  • A person can have more than one marker in their name. For example my full title is Dr Andrew Stapleton, PhD, MChem.
  • The doctor title at the front can be used as a variant to the PhD at the end.

It can be a little bit ambiguous if I was to use Dr Andrew Stapleton, PhD as there are two markers. This could mean that I have two PhD’s, it could mean that I have a PhD and a medical doctorate, or it could just be that I want to use both the doctor and the PhD tags for the one degree.

However, in my experience, I still like to use both the title of doctor at the front and the PhD tag at the end of my name for official purposes.

Academics would rarely use the PhD suffix in everyday communication. They would much rather just use the doctor title.

What is the proper title for a PhD with a doctorate degree?

The proper title for a PhD is Doctor of Philosophy. However, some teachers and professors like to be referred to without their official title.

If you are not sure about how your professor, lecturer, or friend with a PhD wishes to be officially addressed you can ask them.

Most of the time, I like to refer to my colleagues with their doctor title for official purposes, but I do not include the type of doctoral degree at the end of their name. That is much better suited to a business card.

Your lecture may wish to be referred to as:

  • Dr [last name]
  • Dr [first name]

Asking them in the early stages of your relationship is the best way to work out which one they prefer.

If in doubt, always go for the more formal name and nomenclature.

When can you start to use your PhD title after your doctorate? As a PhD student? After your phd thesis?

When you have earned your PhD, you, as a person with a doctoral degree, can start using your title immediately. Although, it can be a little bit confusing as to when you have actually passed your PhD. Is it when you have submitted your dissertation for the advanced degree? Is it when you have received the comments back?

The University of Adelaide says that you can use it from your conferral date:

Students can be conferred on one of five dates during the year and for PhD students the conferral date will be the first available following the completion of all the academic requirements of your degree, including final thesis lodgement and the disbursement of any outstanding financial obligations to the University.

I started using my PhD title as soon as my confirmation letter arrived at my house. It was the first letter from the University that referred to me as Dr Stapleton. I was incredibly excited.

Generally, it is acceptable to use the title “Dr.” both professionally and socially but socially, people very rarely use it – at least in Australia. But you should never use it if you are a PhD student, PhD candidate or enrolled in a PhD program without a previous PhD qualification. 

I do use it in professional settings but it always makes me feel a little bit awkward.

However, there may be some restrictions for certain settings . For example, if have a research degree resulting in a doctor title and you are working in a medical setting – some institutions do not like you to use Dr as it can confuse patients into thinking that you have a medical degree. 

Instead, they ask that you use the PhD tag at the end of your name rather than the doctoral title for official and professional communications.

What is the correct way to write PhD?

When writing about someone’s PhD, the correct way is to write the term in full and capitalize each letter.

This should be done for all academic degrees, not just PhDs.

For example, it would be “Doctor of Philosophy” or “PhD” instead of “Ph.D.”, “Dr.”, or “DPhil”.

Additionally, it is common to mention the field of study in which the degree was earned if known, such as “Doctor of Philosophy in Mathematics”. It is also good practice to include the institution that granted the degree if it is a recognized one.

When writing about someone’s PhD, use proper capitalization and include relevant information like field of study and institution if known to ensure accuracy.

How do you put a PhD in a title?

Putting a PhD in a title is not as complicated as it may sound.

Generally speaking, the proper way to list a PhD in an academic or professional setting is by writing “Dr.” before the name, followed by the person’s full name and the appropriate abbreviations for their degree.

For example, if John Smith has earned a doctorate in psychology, his credentials would be listed as “Dr. John Smith, Ph.D.”

In some cases, such as when addressing someone formally in speech or on a business card, it may also be acceptable to list their credentials as “John Smith, Ph.D.”

Depending on context and personal preference, some people may also choose to list their higher degrees after their names by writing out the entire degree instead of just its abbreviation.

For example, John Smith could choose to write his full title as “John Smith, Doctor of Psychology”

However, I have not seen this in real academic life.

Should the font size of Ph.D. be the same as someone’s name?

The question of whether the font size of a Ph.D. should be the same as someone’s name is an interesting one.

On one hand, it could be argued that the Ph.D. deserves to be highlighted and therefore should be given a larger font size than someone’s name to denote its importance.

On the other, it could be argued that this would not be necessary or appropriate, and that treating everyone equally regardless of their title or degree is more important.

It depends on context and usage – if both names appear in the same document then they should likely have the same font size; however, if one appears in a formal setting such as a diploma or certificate, then it may make sense to give it a larger font size than someone’s name to emphasize its importance and significance.

Ph.Ds (or PhDs) are an important academic achievement and should be respected accordingly but without going overboard by giving them overly large fonts sizes which can take away from rather than add to their importance.

Wrapping up – doctoral title rules

This article has been over everything you need to know that using the PhD title properly and effectively, since the person has worked hard to earn a degree very few people have.

The doctor title can be used in place of the PhD and for incredibly formal communications, such as a business email or card, you can use both.

However, sometimes using both can cause confusion as to whether or not there is a reason first using both the doctor and PhD tags. Nonetheless, many people still use both.

Different types of PhD

Students often have many questions about PhD’s. Is a doctoral degree a PhD? What’s the difference? The pinnacle of education is that of a PhD, doctorate qualification. But did you know that there are different types of PhDs, and how do you choose the right one for you and how can you get PhD help ?

‘PhD’ or Doctor of Philosophy is the most widely known higher qualification. However, there are other types of PhD degrees that specialise in particular subjects or are professional degrees completed in a different format.

Here’s what you need to know about all the higher education degrees available.

PhD/DPhil (Doctor of philosophy)

Many think that DPhil and PhD are different degrees but they are only different names for the same thing. DPhil, an abbreviation for Doctor of Philosophy, is a British term but is hardly used by many universities any more. An academic PhD can be studied in all subjects and are not restricted to certain fields.

A PhD typically involves independent and original research in a particular field or subject. Some PhD degree courses include taught parts, however, the main focus of the course is the completion of a publishable thesis as a result of the independent research.

PhD’s can range from three to four years long for full time students and as long as seven years for part time PhD students. The majority of PhD courses require a Masters degree qualification to apply, however, applications with significant professional experience may be accepted with lower qualifications.

This degree is also an academic type PhD. Aiming to advance theoretical understanding of a subject and often, helping students to advance in their careers rather than focusing on professional development. As a result, PhDs are typically awarded in traditional academic subjects.

type in phd

Th.D (Doctor of theology)

A Th.D is a PhD equivalent degree, however, it can only be undertaken in Christian theology. As a result, this degree is only offered by universities with religious connections. Whereas, a PhD allows students to study any religion and are usually available at most universities. As this is an academic type degree, students will undertake this qualification for careers in academia, leadership, or ministry.

Professional type Doctorates

Another type of higher education is professional type PhD’s. These are higher degrees awarded as part of professional registration such as in fields like Medicine. Or studied as a professional development qualification for career advancing reasons. Often, these degrees are supported by employers as they explore more vocational subjects and aim for a career outside of academia.

In addition, these degrees are taught differently to traditional PhDs including more practical work rather than just theoretical independent study or thesis writing . These degrees reply on smaller research projects, shorter theses, and taught practical work. As a result of this approach, applicants will often need professional experience in the field or subject of study.

DBA (Doctorate in business administration)

A DBA is a PhD equivalent qualification in business administration and management. As a professional type degree, there are key differences between a DBA and a standard PhD. Most notably, a DBA combines management theory with training in the methodologies and techniques necessary to carry out the research.

These degrees are now offered worldwide and take around 4-6 years to complete. A DBA is designed for experienced professional applicants such as those in senior positions, those with an MBA or equivalent looking for a higher qualification, and those looking to refine skills for business development. Therefore, this degree is not suitable for a student straight from a masters degree.

type in phd

DProf (Doctorate of professional studies)

A doctorate of professional studies can be undertaken in any subject like a PhD. However, it focuses on professional development within your chosen work context. Often, the study can be inspired by the students own experience within the field and so the degree can be untaken within a profession or can be more individual.

Each course will vary between subjects and institutions which can mean the subject area you are interested in may only be available at certain universities. Again, this course predominantly includes a large taught part and then self-study presented as a thesis.

EdD/ D.Ed (Doctorate of education)

An EdD is a professional type equivalent PhD qualification in Education. This program is designed for experienced teachers or people in other education roles. Who may be looking to move into more senior roles, work into a totally different role in education, or is interested in contributing to research in the sector.

EdD courses are usually taught in two distinct parts. The first part will focus more on taught modules or trainings in various theories relevant to education and practices essential for the research part of the course. This section is what makes this course more differentiated to a traditional PhD. The second phase of the degree focuses on independent research for a thesis.

Please note, this degree is not a teaching qualification and you should consider a PGCE or other postgraduate teaching qualification.

Other professional type PhD equivalent degrees include:

Dsoc/sci (doctorate of social science).

This type of PhD can cover a variety of topics including management science, psychology, or political science.

EngD (Doctorate of engineering)

An EngD is a PhD equivalent qualification in engineering and applied sciences and includes working closely with a company throughout the degree. This program is suitable for engineering professionals, those looking for higher employment options, or those wanting to contribute to theory and research in their field.

DArch (Doctorate of Architecture)

Less commonly heard of than others, a DArch is a PhD equivalent in Architecture. This qualification helps to prepare students for a career in architecture. Often covering topics like architectural theory, architectural communication, technology, and management.

MD (Doctor of medicine)

A doctorate level degree in medicine and health studies and typically requires students to have years’ worth of postgraduate experience. As a professional type higher degree, this course will combine research and clinical practice.

Are there other types of higher degrees similar to a PhD?

The simple answer is, yes. There are other qualification types that can be deemed similar to a PhD, however, they are not studied in the same way and typically awarded after years of study and professional development. Therefore, they aren’t likely to apply to you but we have included them for your information.

These include Higher Doctorates like, (Doctor of):

  • Civil Law (DCL)
  • Divinity (DD)
  • Literature/Letters (DLit/DLitt/LitD/LittD)
  • Music (DMus/MusD)
  • Science (DS/SD/DSc/ScD)

Higher Doctorates are awarded after the review of a portfolio of published and peer-review research that has been completed over a number of years. This type of degree is awarded as a way to recognise and acknowledge esteemed researchers later in their career.

Another type of higher degree is that of an Honorary Degree. This qualification is awarded to celebrate an individual’s achievements within their field. Usually, it is granted by a university and doesn’t require a record of their academic or professional work like a higher doctorate does.

How do you choose the right PhD Level course for you?

As we have outlined, there are many different types of PhD. Choosing the right PhD course for you is extremely important. Not only are they expensive but they require a huge time and energy investment in studying and conducting research. So how do you decide which course to undertake?

Start by evaluating your goals

What is your goal as a result of this qualification? If you are looking for further career advancement and have been practicing in your field already for a few years, then a professional type doctorate is your best choice. However, if you are looking to contribute to your field of study with original and independent research or are pursuing a career in academia, then a standard PhD degree is for you. Perhaps you would prefer more taught sections of a degree to help develop your research skills and develop as an expert, then a professional type degree would be better.

Look at the subject area you are interested in

Is there a specific professional type degree in your field? If so, and your goal is professional development, then a professional type degree is your best choice. This degree not only allows you to conduct research and be taught skills, they often work with companies or in practical settings.

However, if there is no subject specific degree for your field, then a traditional PhD is best for you. This qualification gives you much more freedom of choice of what and where you study. PhD Centre have many services to help you, from the PhD application help to the full PhD thesis writing .

When do you want to study a PhD degree?

Are you wanting to study a PhD straight after a Masters degree? Often, a PhD might develop on from your Masters degree research. Therefore, a traditional PhD can be the best option if you are looking to pursue higher level study within a short time span from graduating at masters level. On the other hand, if you are already well established in your career, a professional type degree can help build on your experience and expertise and may not be suitable straight out of postgraduate study.

Final thoughts on the types of PhDs

We are sure there are more PhD degrees out there than you might have first thought. The variety and different types of PhD available provide you with many options and methods of gaining a doctorate in your chosen field. What degree is your best choice?

What is a PhD?

A PhD, which stands for “doctor of philosophy”, is the most advanced academic degree. It’s earned through extensive research on a specific topic, demonstrating expertise and contributing new knowledge to the field.

What does “PhD” mean?

The term “PhD” is often used as a synonym for any doctoral-level qualification. Doctorate degrees can often be split into two categories: MPhil and PhD.

Free study abroad guide

Download your Study Abroad Guide for FREE!

An MPhil is similar to a PhD as it includes a research element (which is usually shorter and less in-depth than a PhD thesis, and often more akin to a dissertation undertaken at undergraduate or master’s level). 

MPhil students focus more on interpreting existing knowledge and theory and critically evaluating other people’s work rather than producing their own research. The precise nature and definition of an MPhil can vary among institutions and countries. 

A PhD, meanwhile, follows a more widely known and traditional route and requires students, often referred to as “candidates”, to produce their own work and research on a new area or topic to a high academic standard.

PhD requirements vary significantly among countries and institutions. The PhD, once completed, grants the successful candidate the title of “doctor of philosophy”, also called PhD or DPhil.

What is a professional doctorate?

A professional doctorate is a kind of degree that helps people become experts in their fields. Instead of focusing mainly on theory and research like a regular PhD, a professional doctorate is all about practical skills and knowledge.

This kind of doctorate is great for students who want to get better at their jobs in areas like teaching, healthcare, business, law or psychology. The courses and projects in these programmes are designed to tackle real problems you might face at work.

For example, you might have heard of the doctor of education (EdD), doctor of business administration (DBA), doctor of psychology (PsyD) or doctor of nursing practice (DNP). These programmes combine learning, hands-on projects and sometimes a thesis paper or essay to show you’re skilled at solving on-the-job challenges.

How long does it take to study a PhD?

The time required to complete a PhD can vary significantly based on several factors. Generally, a full-time PhD programme takes around three to six years to finish. However, it’s important to take into account individual circumstances and the nature of the research involved.

1. Full-time vs. part-time: If you’re studying full-time, dedicating most of your time to your studies, it usually takes about three to four years to complete a PhD. However, studying part-time while managing other commitments might extend the duration. Part-time PhDs can take around six to eight years, and sometimes even longer.

2. Nature of research: The complexity of your research proposal can influence the time required. Certain research questions may involve intricate experiments, extensive data collection or in-depth analysis, potentially leading to a longer completion timeline.

3. Field of study: The subject area you’re researching can also affect the necessary time. Some fields, such as sciences or engineering, might involve more hands-on work, while theoretical subjects might require more time for literature review and analysis.

4. Supervision and support: The guidance and availability of your academic supervisor can affect the pace of your research progress. Regular meetings and effective communication can help keep your studies on track.

5. Thesis writing: While the research phase is crucial, the stage of writing your thesis is equally significant. Organising and presenting your research findings in a clear and cohesive manner can take several months.

6. External commitments: Personal commitments, such as work, family or health-related factors, can influence your study time. Some students need to balance these alongside their PhD studies, potentially extending the duration.

7. External Funding: The availability of funding can also affect your study duration. Some funding might be linked to specific project timelines or research objectives.

So, although a PhD usually takes between three and six years of full-time study, with potential variations based on research complexity, enrolment as part-time or full-time, field of study and personal circumstances. It’s vital to have a realistic understanding of these factors when planning your PhD journey.

How long is a PhD in the UK?

In the UK, the length of a PhD programme typically ranges from three to four years of full-time study. As explained above, there are many factors to consider.

How long is a PhD in the US?

Similarly to the UK, in the United States, the duration of a PhD programme can vary widely depending on the field of study, research topic and individual circumstances. On average, a full-time PhD programme in the US typically takes between five and six years to complete.

Why does it take longer to study a PhD in the US?

PhD programmes generally take longer to complete in the US than in the UK due to various factors in the education systems and programme structures of each country:

1. Programme structure: UK PhD programmes often emphasise early, focused research from the first year, leading to shorter completion times. In contrast, US programmes commonly include more initial coursework in your first and second year and broader foundational training, which can extend the overall duration.

2. Course work requirements: Many US PhD programmes require a lot of course work, which can lengthen the time needed to finish. UK programmes tend to have fewer or no course work demands, allowing students to concentrate primarily on research skills.

3. Research funding: In the UK, PhD funding is often awarded with specific timeframes in mind, motivating completion of the research degree in the agreed duration. In the US, funding approaches can vary, requiring students to secure funding from multiple sources, potentially affecting their progress and completion time.

4. Teaching responsibilities: Some US PhD students take on teaching roles as part of their funding, dividing their time and potentially prolonging their studies.

5. Research approach: Differences in research methodologies and project scopes can affect the time needed for data collection, experimentation and analysis.

6. Academic culture: The US education system values a well-rounded education, including coursework and comprehensive exams. This can extend the time before full-time research begins. UK PhD programmes often prioritise independent research early on.

7. Part-time and work commitments: US PhD candidates might have more flexibility for part-time work or other commitments, which can affect research progress.

8. Dissertation requirements: US PhD programmes generally include a longer and more comprehensive dissertation, involving more chapters and a broader exploration of the research topic.

These variations in programme structures, funding models and academic cultures contribute to the differing completion times between the two countries.

What qualifications do you need for a PhD?

To be eligible for a PhD programme, certain educational qualifications are generally expected by universities. These qualifications serve as indicators of your readiness to engage in advanced research and contribute to the academic community.

First, an undergraduate or bachelor’s degree in a relevant field is typically the most common requirement. This degree provides you with a foundational understanding of the subject and introduces you to basic research methodologies. It serves as a starting point for your academic journey.

Do you need a master’s degree to get into a PhD programme?

In addition to an undergraduate degree, many PhD programmes also require candidates to hold postgraduate or master’s degrees, often in fields related to the intended PhD research. A master’s degree offers a deeper exploration of the subject matter and enhances your research skills. Possessing a master’s degree signifies a higher level of expertise and specialisation.

The combination of both undergraduate and postgraduate degrees demonstrates a solid academic background. This background is crucial before you engage in doctoral study because pursuing a PhD involves more than just knowledge; it requires advanced research abilities, critical thinking and the capacity to provide an original contribution and new insights into the chosen field of study.

While these qualifications are usually requested, there are exceptions. Some institutions offer direct-entry programmes that encompass bachelor’s, master’s and PhD degrees in a streamlined structure. This approach is often seen in scientific and engineering disciplines rather than humanities.

In exceptional cases, outstanding performance during undergraduate studies, coupled with a well-defined research proposal, might lead to direct entry into a PhD programme without requiring a master’s degree.

Admission requirements can vary between universities and programmes. Some institutions might have more flexible prerequisites, while others could have more stringent criteria. Make sure that you thoroughly research all admission requirements of the PhD programmes you’re interested in to ensure you provide the right information.

Are PhD entry requirements similar in other countries?

PhD entry requirements in Canada and Australia can be somewhat similar to those in the UK and the US, but there are also some differences. Just like in the UK and the US, having a bachelor’s degree followed by a master’s degree is a common way to qualify for a PhD in Canada and Australia. However, the exact rules can vary, such as how much research experience you need or the grades you should have.

In Canada and Australia, as in the UK and the US, international students usually need to show their English language skills through tests like IELTS or TOEFL. And, like in other places, you might need to give a research proposal to explain what you want to study for your PhD.

But remember, even though there are some similarities, each country has its own rules.

How much does it cost to study a PhD?

The cost of pursuing a PhD can vary significantly between international and home (domestic) students, and it depends on the country, university and programme you choose.

United Kingdom (UK)

Home students in the UK often pay lower tuition fees compared with international students. Home students might also have access to government funding or subsidised tuition rates.

International students typically pay higher tuition fees, which can vary widely depending on the university and programme. Fees can range from around £10,000 to £25,000 or more per year.

United States (US)

PhD programme costs in the US can be quite high, especially for international students. Public universities often have lower tuition rates for in-state residents compared with out-of-state residents and international students.

Private universities in the US generally have higher tuition fees, and international students might be charged higher rates than domestic students.

Canadian universities often charge higher tuition fees for international students compared with domestic students.

Some universities offer funding packages that include tuition waivers and stipends for both domestic and international doctoral students.

In Australia, domestic students (Australian citizens and permanent residents) usually pay lower tuition fees than international students.

International students in Australia might have higher tuition fees, and costs can vary based on the university and programme.

Apart from tuition fees, other aspects play a role in the overall financial consideration:

PhD studentship: Many universities offer PhD studentships that provide financial support to research students, covering both tuition fees and a stipend for living expenses.

Stipend and housing: Stipends are designed to cover living expenses. Stipend amounts can vary depending on the university and location. If you’re studying in London in the UK, stipends might be higher to account for the higher living costs in the city. Some universities also offer subsidised or affordable housing options for doctoral students.

Tuition and stipend packages: Some PhD programmes provide funding packages that include both tuition waivers and stipends. These packages are to help relieve the financial burden on students during their doctoral studies.

Research the financial support options provided by the universities you’re interested in to make an informed decision about the cost of your PhD journey.

What funding options are available for PhD candidates?

PhD candidates have various funding options available to support their studies and research journeys. Some of these options include:

PhD scholarships: Scholarships are a common form of financial aid for PhD candidates. They are awarded based on academic merit, research potential or other specific criteria. Scholarships can cover tuition fees and provide a stipend for living expenses.

Bursaries: Bursaries are another form of financial assistance offered to students, including PhD candidates, based on financial need. They can help cover tuition fees or provide additional financial support.

In the UK, specific funding options are available:

Regional consortium: Some regions have research consortiums that offer funding opportunities for doctoral candidates. These collaborations can provide financial support for research projects aligned with specific regional needs.

UK research institute: Research councils in the UK often offer stipends to PhD candidates. These stipends cover living expenses and support research work.

University-based studentship: Many UK universities offer studentships. You can read more about these above.

In the USA, there are also funding options available:

Research assistantships (RAs): Many universities offer research assistantships where PhD candidates work on research projects under the guidance of faculty members. In exchange, they receive stipends and often have their tuition waived.

Teaching assistantships (TA): Teaching assistantships involve assisting professors in teaching undergraduate courses. In return, PhD candidates receive stipends and sometimes tuition remission.

Fellowships: Fellowships are competitive awards that provide financial support for PhD candidates. They can come from universities, government agencies, private foundations and other institutions. Fellowships can cover tuition, provide stipends and offer research or travel funds.

Graduate assistantships: Graduate assistantships include a range of roles, from research and teaching to administrative support. These positions often come with stipends and sometimes include tuition benefits.

External grants and fellowships: PhD candidates can apply for grants and fellowships from external organisations and foundations that support research careers in specific fields. Examples include the National Science Foundation (NSF) and the Fulbright Programme.

Employer sponsorship: In some cases, employers might sponsor employees to pursue PhDs, especially if the research aligns with the company’s interests.

What does a PhD Involve?

How does a PhD work?

A PhD includes thorough academic research and significant contributions to your chosen field of study. The timeline for completing a PhD can significantly vary based on the country, college or university you attend and the specific subject you study.

The duration of a PhD programme can vary based on factors such as the institution’s requirements and the academic discipline you’re pursuing. For instance, the timeline for a PhD in a science-related field might differ from that of a humanities discipline.

UK PhD timeline example

Looking at a typical PhD degree in a London higher education institution, we can consider this example timeline.

In the initial year of your PhD, you’ll collaborate closely with your designated academic supervisor. This collaboration involves refining and solidifying your research proposal, which lays the foundation for your entire doctoral journey.

This is also the time to establish a comprehensive plan, complete with well-defined milestones and deadlines. A crucial aspect of this year is conducting an extensive literature review, immersing yourself in existing academic works to understand the landscape of your chosen research area. It’s important to make sure that your research idea is original and distinct from prior studies.

As you begin the second year, you’ll actively collect data and gather information related to your research topic. Simultaneously, you’ll initiate the process of crafting your thesis. This involves combining your research findings and analysis into sections of your thesis document.

This is also the phase where you might have opportunities to share your research insights at academic meetings, conferences or workshops. Depending on the programme, you might even engage in teaching activities. Some PhD candidates also begin contributing to academic journals or books, showcasing their findings to a broader audience.

The third year of a PhD programme often marks the final stage of your research efforts. This is when you dedicate substantial time to writing and finalising your complete thesis. Once your thesis is completed to the highest standard, you’ll submit it for thorough evaluation.

A significant milestone in the third year is the viva voce, an oral examination where you’ll defend your thesis before a panel of experts in your field. The viva voce is an opportunity to showcase your deep understanding of your research and defend your findings.

Why should you do a PhD?

For many people, acquiring a doctorate degree is the pinnacle of academic achievement, the culmination of years of commitment to higher education.

However, the act of pursuing a PhD can be a complex, frustrating, expensive and time-consuming exercise. But with the right preparation, some sound advice and a thorough understanding of the task at hand, your years as a doctoral student can be some of the most rewarding of your life. 

People choose to work towards a doctorate for many reasons. If you are looking to pursue an academic position, such as university lecturer or researcher, then a PhD is usually required.

Many people obtain a PhD as part of a partnership with an employer, particularly in scientific fields such as engineering, where their research can prove useful for companies.

In some cases, however, PhDs are simply down to an individual’s love of a subject and their desire to learn more about their field.

What are some benefits of studying a PhD?

Pursuing a PhD can have many benefits that extend beyond academic achievement, encompassing personal growth, professional advancement and meaningful contributions to knowledge.

One of the most notable benefits of a PhD is the potential for tenure in academia. Attaining tenure provides a level of job security that allows you to delve into long-term research projects and make enduring contributions to your field. It signifies a stage where you can explore innovative ideas and pursue in-depth research, fostering your academic legacy.

While not obligatory, the opportunity to collaborate on research projects with your supervisor is another valuable aspect of a PhD pursuit. These collaborations might even come with financial compensation, offering real-world experience, skill development and practical applications of your research. Engaging in such collaborations can enrich your research portfolio and refine your research methodologies.

A pivotal aspect of a PhD journey is the chance to publish your original research findings. By disseminating your work in academic journals or presenting it at conferences, you contribute to the expansion of knowledge within your field. These publications establish your expertise and reputation among peers and researchers worldwide, leaving a lasting impact.

The pursuit of a PhD can provide a unique platform to build a diverse network of colleagues, mentors and collaborators. Engaging with fellow researchers, attending conferences and participating in academic events offer opportunities to make valuable connections. This network can lead to collaborations, expose you to a spectrum of perspectives and pave the way for future research endeavours.

What is a PhD thesis? And what is a PhD viva?

A PhD thesis will be produced with help from an academic supervisor, usually one with expertise in your particular field of study. This thesis is the backbone of a PhD, and is the candidate’s opportunity to communicate their original research to others in their field (and a wider audience).  PhD students also have to explain their research project and defend their thesis in front of a panel of academics. This part of the process is often the most challenging, since writing a thesis is a major part of many undergraduate or master’s degrees, but having to defend it from criticism in real time is arguably more daunting.  This questioning is known as a “viva”, and examiners will pay particular attention to a PhD’s weaknesses either in terms of methodology or findings. Candidates will be expected to have a strong understanding of their subject areas and be able to justify specific elements of their research quickly and succinctly.

In rare cases, students going for a PhD may instead be awarded an MPhil if the academic standard of their work is not considered fully up to par but still strong enough to be deserving of a qualification.

Can you do a PhD part time? 

Many PhD and MPhil candidates choose to pursue their qualification part time, in order to allow time to work and earn while studying. This is especially true of older students, who might be returning to academia after working for a few years. 

When applying, you should always speak to the admissions team at your university to ensure this is possible and then continue to work with your supervisor to balance all your commitments. 

Can I do a PhD through distance learning?

This is something else that you will need to check with your university. Some institutions offer this option, depending on the nature of your research. 

You will need to be clear how many times you will need to travel to your university to meet with your supervisor throughout your PhD. 

Your PhD supervisor

Choosing the right PhD supervisor is essential if you want to get the most out of your PhD. Do your research into the faculty at the institution and ensure that you meet with your proposed supervisor (either virtually or in person) before fully committing. 

You need to know that not only do they have the right expertise and understanding of your research but also that your personalities won’t clash throughout your PhD. 

Remember, to complete your PhD, you will need a strong support network in place, and your supervisor is a key part of that network. 

Coping with PhD stress

If you do decide to embark on a doctorate, you may well encounter stress and anxiety. The work involved is often carried out alone, the hours can be long and many students can suffer from the pressure they feel is on their shoulders.

Ensuring that you check in regularly with your emotions and your workload is crucial to avoid burnout. If you have other commitments, such as a job or a family, then learning to balance these can feel overwhelming at times. 

Give yourself regular breaks, speak to your supervisor and ensure that you know what university resources and support systems are available to you in case you need to access them. 

Post-doctorate: what happens after you finish your PhD?

Many PhD graduates pursue a career in academia, while others will work in industry. Some might take time out, if they can afford to, to recover from the efforts of PhD study.

Whatever you choose to do, undertaking a PhD is a huge task that can open up a range of doors professionally. Just remember to take some time out to celebrate your achievement. 

How does a PhD affect salary and earning potential?

How much does a professor with a PhD make a year?

Professors with PhDs can earn different amounts depending on where they work and their experience. In the UK, a professor might make around £50,000 to £100,000 or more each year. In the US, it's between about $60,000 and $200,000 or even higher. The exact salary depends on things like the place they work, if they have tenure, and what they teach.

How much does a PhD add to salary?

Having a PhD can make your salary higher than if you had a lower degree. But exactly how much more you earn can change. On average, people with PhDs earn more than those with bachelor’s or master’s degrees. The increase in salary is influenced by many things, such as the job you do, where you work and what field you’re in.

In fields such as research, healthcare, technology and finance, your knowledge and skills from your PhD can potentially help you secure a higher salary position.

In the end, having a PhD can boost your earning potential and open doors to well-paying jobs, including professorships and special roles in different areas. But the exact effect on your salary is influenced by many things, so ensure you weigh the cost against the benefit.

How to choose a PhD programme?

Choosing a PhD programme involves defining your research interest, researching supervisors and programme reputation, evaluating funding options, reviewing programme structure, considering available resources, assessing networking opportunities, factoring in location and career outcomes, visiting the campus if possible and trusting your instincts.

How can I find available PhD programmes?

What is a doctorate.

A doctorate is a research-based academic degree. It is considered a terminal degree in most disciplines, meaning it represents the highest level of education a student can obtain in their chosen field.

A doctorate is awarded to students who have undergone a lengthy research process and made a significant contribution to the body of knowledge in their field of study. It takes multiple years to complete, during which students work closely with a supervisor and focus on a specific dissertation topic. Completing a doctorate might also involve teaching and comprehensive examinations.

A doctorate serves as solid proof of a person’s level of knowledge and expertise. It demonstrates that you have mastery over your chosen subject, and helps establish you as an expert. This level of expertise comes with top-tier job opportunities and the potential to earn top salaries in your chosen profession.

Doctorate vs PhD: Key Differences

While many people use the terms doctorate and PhD interchangeably, there are key differences between the two. These differences have to do with the application of these degrees. However, both terms refer to terminal degrees, so they hold the same value.

A Doctor of Philosophy degree, or PhD, is a research-oriented degree that demonstrates a person’s ability to contribute new knowledge to their chosen field. A student who pursues a PhD usually does so to answer a specific question, conduct original research to provide an answer, and use their findings to advance their field.

On the other hand, the term doctorate is broader and typically refers to a professional or clinical degree. This means that a person who obtains it has demonstrated an ability to apply advanced knowledge in a particular field in their professional life. Professional doctorates of this kind are awarded, for instance, to medical doctors or doctors of juridical science.

PhD Requirements: How to Get a PhD

While each PhD degree program will have unique requirements depending on the school and field of study, there are some common requirements you need to complete to get a PhD. Keep reading to find out about the most common requirements to earn your advanced degree.

PhD Statement of Purpose

A PhD statement of purpose is a document that clearly outlines your goals for your PhD, your academic credentials, and the reasons why an academic committee should approve your project. It is typically between 500 to 1,000 words long and gives prospective students an opportunity to explain how their research project will make a relevant contribution to their field.

How Many Credits Is a PhD?

Typically, it takes between 90 and 120 credits to complete your PhD studies. However, this number can be as low as 60, depending on the degree type, area of study, and state, regional, or institutional requirements. Credit hours for graduate students are usually divided between course work, research hours, and dissertation work.

Other Common Requirements for a PhD

  • Coursework. While coursework is not the main focus of a PhD, students will usually have to enroll in a few core courses during their first or second year of grad school. They might also have the opportunity to enroll in elective courses, which offer a chance to learn about other fields of study.
  • Qualifying exams. A common component of many PhD programs is a set of qualifying exams. Students must successfully pass these comprehensive exams toward the end of their degree in order to demonstrate their level of competence in their field. These tend to be oral exams.
  • Teaching. Many PhD programs include a teaching component. Students are required to teach basic courses, typically to fresh undergrad students, which helps them develop teaching skills.
  • Research. Conducting original research on a particular subject is typically the main component of a doctorate program, and takes up the bulk of doctoral candidates’ time.
  • Dissertation. Throughout their program, PhD candidates need to complete a dissertation based on the original research they’ve conducted. Graduate students do this under the guidance of a qualified faculty member.
  • Dissertation defense. Once the dissertation is approved, PhD students need to successfully defend their research in front of a panel of experts in their field before they are awarded their degree. This is the final step in the dissertation process.

How Do PhD Programs Work?

Typically, PhD degree programs work based on a mix of coursework and research conducted over three to four years, although this can last longer depending on the program and the pace at which a student completes their research. Coursework is typically completed towards the beginning of the program, and towards the end, the dissertation or thesis becomes the main focus.

In addition, students must fulfill other program requirements throughout this period. This might include teaching undergraduate students, completing a residency, passing qualifying exams, or attending conferences or colloquia. The final step is usually an oral defense in front of a panel of experts, who are selected to evaluate the quality of the research and the value of the results obtained.

No, a master’s degree is not always required to pursue PhD studies. Many programs in the US allow students to apply to a PhD program straight after completing their bachelor’s degree. Other programs offer dual degrees, meaning that you will obtain a master’s degree while you work toward your doctorate.

What Comes After a Doctorate Degree?

In many fields, the usual step after a doctorate degree is a postdoc. This is an option for those wishing to pursue a career in academia and continue doing research in their field. However, an academic career is not the only option. Because a doctorate is a terminal degree, graduates can easily move on to professional positions in other types of organizations in their chosen field.

PhD Dissertation vs Thesis

The main difference between a dissertation and a thesis is the scope of the research being conducted and the type of degree you are awarded after completing it. Often, the terms are used interchangeably, or they can hold different meanings in European countries, which causes some confusion regarding their nature. Keep reading to understand the differences between a PhD dissertation and a thesis in the US.

What Is a PhD Dissertation?

A PhD dissertation is a piece of scholarly work that presents the original research carried out by a doctoral student during the length of their program. It discusses the scope, methodology, results, and conclusions of the research at length. The end goal of a doctoral dissertation is to produce results that help advance human knowledge in a given field.

PhD Dissertation Defense

A PhD dissertation defense is the process in which a PhD candidate defends their research in front of a panel of experts in their field. During the defense, members of the panel ask questions regarding the information presented, providing the candidate an opportunity to back up their work and demonstrate the level of expertise they’ve achieved after years of dedicated work.

What Is a PhD Thesis?

In the US, as opposed to some European countries, the term thesis refers to a shorter academic paper that is usually presented for the completion of a master’s degree. It can also sometimes be a requirement for honors students completing a bachelor’s degree. The information presented in a thesis is usually drawn from existing sources, rather than from original research conducted by the student.

PhD Thesis Defense

A thesis defense is usually not a mandatory requirement for master’s students, although this varies according to your school and department. The thesis is still an in-depth piece of scholarly writing and serves as a testament to a student’s mastery of a given subject, and a defense serves as an opportunity to engage a panel of experts and defend the contents of your paper.

How Long Does It Take to Earn a Doctorate?

Most doctoral programs are designed to be completed in four to six years. However, it can take up to seven and a half years to earn a doctoral degree from the start of graduate school, according to data presented by the National Science Foundation.

A number of factors can affect how long it takes students to earn their PhDs. They include the structure of their chosen program, the type of research being conducted, and the support provided by the institution. On average, students completing doctoral programs in science and engineering fields finish faster than their counterparts in non-science and engineering fields.

How Hard Is It to Get a PhD?

It can be very hard to get a PhD. Working for several years on a particular dissertation topic can be very trying. Aside from the time commitment, the depth of research that is part of the dissertation process can also be challenging. Admissions to a top education institution can be extremely competitive, as usually there are only a handful of positions available for hundreds of applicants.

What Is the Easiest PhD to Get?

PhDs in the humanities, social sciences, and education are typically regarded as the easiest to obtain. However, this truly comes down to how interested you are in your chosen dissertation topic and your level of commitment to making a relevant contribution to human knowledge, both of which can greatly influence your perception of the difficulty of the degree.

How Much Does a PhD Cost?

According to data from the National Center for Education Statistics, the average yearly cost of graduate programs in the US is $19,792. Data from the QS World University Rankings suggest that the yearly cost of a PhD in the US ranges from $28,000 to $40,000. The total cost of a PhD can greatly vary depending on the university, length of the program, and funding options available for doctoral study.

Through this process, you will be making important contributions and developing groundbreaking practices in your area.

Transferable Skills

Aside from your ability to work independently and conduct research in your area of expertise, you will also develop a variety of transferable skills that will be useful to you no matter what you choose to do after graduation.

Throughout your program, you will be participating in committees, teaching, organizing conferences, publishing your work, and meeting other experts. As a result, you will develop multipurpose skills, including time and project management, communication and interpersonal skills, and leadership skills.

While you pursue your academic degree, you will be participating in academic conferences, workshops, seminars, and colloquia. This, in turn, means you will have ample opportunities to connect with other doctoral students in your field and in other areas of knowledge. The connections you make through your PhD can lead to career opportunities and expand your social circle in new and interesting ways.

How to Earn a Doctoral Degree

So, how do you earn a doctoral degree? While there is work to be put in, the process is actually quite straightforward. Keep reading to find out how you can embark on the path toward your PhD.

The first step to earning your doctorate is to complete a bachelor’s degree at the undergraduate institution of your choice. Depending on your chosen field, you might need to obtain a degree in a specific discipline, which can then pave the way for your graduate studies.

If a bachelor’s degree is not an option right away, you can start by obtaining an associate degree , which can even be done through the best online community colleges . While you obtain your undergraduate degree, make sure to seek out career advice from experts who can help you decide how to best use your time and embark on the right academic path.

While earning a master’s degree is not mandatory to apply to a PhD program, doing so can offer you a competitive advantage. It will give you a chance to deepen your knowledge on a particular topic, connect with professors and gather recommendations, and test the waters regarding your chosen field.

In order to successfully apply to a master’s degree program, you will have to provide your GPA, letters of recommendation, and sometimes standardized test scores. For instance, if you’re interested in pursuing a Master’s Degree in Mathematics , you will need to prep for the GMAT and submit your scores. Be sure to check the requirements of your chosen school and department.

Whether you have completed your master’s or are applying straight after your bachelor's, make sure to spend some time choosing your specific research area and the type of PhD you wish to pursue. This is also an excellent time to assess funding opportunities and contact potential supervisors to gauge their interest in and ability to support you during your studies.

In order to enroll in a doctoral program, you will need to provide quite a few documents with your application. Every school is different, but the most common requirements are transcripts, letters of recommendation, and a strong statement of purpose. Make sure you check the specific requirements of your chosen program, and prepare to be interviewed by faculty members.

After being accepted into a doctoral program, you should outline what the next few years will look like. What requirements do you need to complete to earn your PhD? Spend time crafting a realistic timeline that can help you stay on track and complete every step successfully. This includes teaching, participating in conferences, and successfully completing your qualifying exams.

The final step to obtaining your PhD is to successfully complete your research and compile your results in your dissertation. Once it is reviewed and approved by your supervisor and readers, you will have to defend it as well. It can be a trying process, but the results will be worth it.

How to Choose a PhD Program

In order to choose a PhD program that is right for you, there are several factors you should consider. A PhD is a strong commitment both in terms of time and money, so the decision shouldn’t be made lightly. Keep reading to find out how to choose a PhD program.

PhD Acceptance Rates

The PhD acceptance rates of a university give you an idea of how likely you are to be admitted to your chosen program. This number is a reflection of how competitive a program is and the funding the department receives. Use this information to orient yourself to the selection process, as applying to a variety of programs with different acceptance rates can increase your chances of being accepted into one of them.

Keep in mind that acceptance rates are usually measured by department, not university. For instance, Columbia University has an acceptance rate of four to six percent for its psychology PhD program , and an acceptance rate of five to seven percent for its history PhD .

PhD Dropout Rates

PhD dropout rates are important to consider, as they give you an idea of how supported students are in a particular program and how likely you are to complete your doctorate. In the US, PhD attrition rates, or dropout rates, can range from 40 to 50 percent , so take your time to find a university and program with a high success rate to ensure you will be able to finish and obtain your degree.

Faculty Members

One of the key relationships you will have during your time as a PhD student will be with your supervisor. You will also be working closely with other members of your department. As such, make sure to research the faculty to ensure that their interests and research projects align with your own. During the research stage, you can even reach out to them to find out about the department, ask about funding opportunities, and receive relevant career advice.

Funding Opportunities

A PhD can be costly, but there are many ways to offset those costs to make it more manageable. Be it scholarships, grants, or work opportunities, make sure to research all funding opportunities available so you can select a program that aligns with your financial situation. Many universities offer fully-funded programs to outstanding students, so do your homework and find a program that doesn’t leave you financially crippled in the long run.

When you commit to a PhD, you are also committing to several years of work. Unless you are planning to complete your program fully online, you should take into account the place where you will be moving to continue your studies.

Do you prefer big cities or small college towns? Which part of the country would you be willing to relocate to? Take some time to reflect on your preferences so you can choose the best location according to your needs and preferences.

Ph.D. vs. Doctorate: What are the Differences?

Picture of UOTP Marketing

phd-vs-doctorate

For those who have a deep-seated attitude, pursuing a doctoral degree can be a tough yet beneficial journey. Currently enrolled in a doctorate program means that a person has already scooched over college admissions, went through high stake tests and exams, and finished all those research papers and long hours spent in university libraries hitting the books. While studying for a doctorate entails asserting oneself to an extensive amount of quality time and money , its significance and purpose usually pave the way to a lucrative end.

After having finished the Master’s Degree , students begin to think about their next step in their academic career. Then, paradoxically, while navigating through academia, they find themselves baffled by the immense terms and terminologies used to label specific degrees. Because the terms “Doctorate” and “Ph.D.” are somehow interlocked and overlap, and because “PhD” is sometimes used inconsistently, it can lead to considerable confusion. Ph.D. vs. Doctorate? You might wonder what their difference is, and why they are important. E xplaining what each of these terms stands for, the difference between them, and why they are valuable, can help you steer yourself down the right path from the outset.

Doctorate Degree vs. Ph.D.

what-is-a-phd

At first glance, it is pretty easy to confuse these two terms. But it is important for everyone to be able to make a distinction between the two. In this article, we will discuss the difference between Ph.D. and Doctorate in detail in order to get rid of any confusion you may have. In the academic world, the terms Doctorate and Ph.D. are currently used interchangeably. Both of them are the top cap of the ladder. However, a doctorate is mostly used as an umbrella term covering many fields ranging from professional degrees, humanities, and scientific disciplines.

A Ph.D. or Doctor of Philosophy, on the other hand, is a subcategory of a doctoral degree, it is much more distinct and clear-cut and is usually narrower in nature encompassing only humanities and scientific fields. In plain English, when someone says they are enrolling on a doctoral degree, it means they are doing a Ph.D. in a specific field. So, technically, in common parlance, there is no difference between the two terms.

But at the other end of the spectrum, one should be careful not to confuse a professional doctoral degree with a Ph.D. The former is more practical and is designed to prepare students to apply existing knowledge to find solutions to real-life problems and has a direct application to a particular profession.

A Ph.D. is theoretical by nature and is more academic and research-focused. it is often fixed on disseminating knowledge by conducting authentic research which means reviewing and identifying gaps in current literature and evaluating the relevance of existing and emerging theories within a particular field.

What Is a Ph.D. Degree and Why Should You Go for It?

Students who acquire a Ph.D. are justly proud — they wear it as a badge of identity in the academic elite. Traditionally, a Ph.D. was associated with teaching, which from Latin licentia docendi meant “license to teach”. However, the concept of Ph.D. has been on shifting sands nowadays and has become a more general term that isn’t necessarily confined to teaching only.

The Value of a PhD

types-of-doctorate-degrees

Obtaining a Ph.D. helps you capitalize on the emerging academic opportunities making you more easily identifiable to employers or businesses seeking to fill professional, higher-level job positions. Many of these career options, conversely, are not available to those who do not belong to the Ph.D. club. While pursuing a Ph.D. requires devoting a tremendous effort and time and making significant personal sacrifices pushing the boundaries of knowledge, it’s all in service of the area of study you’re most passionate and zealous about. Ultimately, once you’ve attained your Ph.D., you will have achieved the pinnacle of education— something not too many people have or are able to accomplish.

What Is a Doctorate Degree?

A doctoral or doctorate degree is usually the most advanced degree one can earn in an academic discipline. Many pursue a doctorate degree to increase their professional credibility, be acknowledged as an expert in a specific field, and improve their resume.

A doctorate degree is a graduate-level credential that is usually earned after multiple years of graduate school. Earning a doctoral degree requires a significant level of research and work. In order to get this degree, one has to research a subject thoroughly, conduct new research and analysis, and provide a solution or interpretation into the field. But what types of doctoral degrees are available?

Types of Doctorate Degrees

There are two categories of doctorate degrees: an academic degree and a professional doctorate degree. An academic degree focuses on research, data analysis, and the evaluation of theory. A professional doctorate degree, on the other hand, is considered a terminal degree, which means that one has achieved the most advanced degree in the field. This degree is specifically designed for working professionals who want to grow in their careers.

Professional Doctorate Degrees

A professional doctorate is designed for working professionals who have experience in the field and want to increase their knowledge, improve their credibility, and advance their careers. This degree focuses on applying research to practical issues, coming up with interpretation and solutions, as well as designing effective professional practices within a particular field.

Professional doctoral degrees include:

Doctor of Business Administration (DBA)

The DBA degree is ideal for students who already have a general business background and are interested in delving deeper into the practical and theoretical aspects that underpin business education. More to the point, in DBA you will develop the ability to solve real-life problems, discover the relevant expertise to innovate and uphold complex business issues and so much more. Upon completion, DBA students will possess enhanced leadership and strategic skills as well as the tools to propel their careers in today’s marketplace. The Business Administration industry is keen on finding such graduates with business skills and this is indicated by the immense job positions currently available.

Doctor of Education (Ed.D.)

If you are interested in setting your eyes on creating lifelong learning among your students, making a positive influence in educational culture, contributing to the growing body of research in the education realm , or just enhancing your subject matter expertise, the Doctor of Education program ticks all the boxes.

This degree will be highly beneficial when working directly with patients who need psychology services. In addition, this degree allows doctors of psychology to confidently function as researchers and clinicians.

How to Choose a Ph.D. Program?

Choosing a Ph.D. program can be pretty challenging; it is a big academic decision and investment that requires commitment and perseverance. But how can you pick the right Ph.D. program for you? Well, there are some tips to help you choose the best fit for your goals and preferences:

  • Think about the reasons why you want a Ph.D., what you expect to gain from it, and whether it is compatible with your professional goals.
  • Consider your research environment.
  • Take your time to research, compare, and consider multiple opportunities carefully.
  • Pick a subject that interests and motivates you but is also practical.
  • Ask your professors and other scholars in the field for advice.

All in all, the terms “Doctorate’’ and “Ph.D.” are in essence the same, which means all Ph.D. students are Doctoral students as well. On the other hand, earning a Ph.D. degree is no joke. If anything, Ph.D. students have the tenacity, patience, persistence, and years of hard work that you can vouch for. Ultimately, deciding what type of doctoral degree you should hop on, depends on your career goals, what you are passionate about and how you are going to achieve it.

AP Style Academic Degrees

Home » AP Style » AP Style Academic Degrees

Sometimes it is necessary to establish the credentials of a subject in your text. When you need to do this, the AP Stylebook prefers you to write out the title of a degree in a phrase and to avoid using an abbreviation. For example,

  • Correct: John Smith, who has a doctorate in astronomy, showed us constellations in the night sky.
  • Wrong: John Smith, who has a Ph.D. in astronomy, showed us constellations in the night sky.

Bachelor Degree or Bachelor’s Degree?

AP Style states that you should use an apostrophe in bachelor’s degree and master’s degree. For example,

  • Correct: I have two bachelor’s degrees and one master’s degree.
  • Wrong: I have two bachelors degrees and one masters degree.
  • Wrong: I have two bachelor degrees and one master degree.

An associate degree, however, does not use an apostrophe. For example,

  • Correct: I received my associate degree before my bachelor’s.
  • Wrong: I received my associate’s degree.

There is also no apostrophe in Bachelor of Arts, Master of Science, etc.

  • Correct: I have a Bachelor of Arts in Linguistics.
  • Wrong: I have a Bachelor’s of Arts in Linguistics.

Abbreviation of AP Style Academic Degrees

Use such abbreviations as B.S., M.S., LL.D., J.D., and Ph.D. only when you need to identify many individuals by degree on first reference and doing so in the AP Style academic degrees preferred way would be cumbersome. You should use abbreviations like these only after full names, never after just a last name.

When an academic abbreviation is used after a full name, commas should set it off. For example,

  • Charles Smith, Ph.D., will present tonight’s lecture.

You should never precede a name with a courtesy title for an academic degree and then also follow it with the abbreviation for the degree in the same reference. For example,

  • Wrong: Dr. Smith, Ph.D., will present tonight’s lecture.
  • Correct: Dr. Smith will present tonight’s lecture.
  • Correct: Charles Smith, Ph.D., will present tonight’s lecture.

Should I Write Ph.D. or PhD? (Complete Guide)

As some of you are probably aware, the kind of English used on my side of the pond (England) is sometimes a bit different to the English used in the land of burgers and Trump.

Some words are spelt differently. But others just have a few bits of grammar difference.

Today, I want to look at the difference between Ph.D. and PhD. We’ll look at which one is correct, what it stands for, and why it’s a bit odd that it stands for that.

Should I Write Ph.D. Or PhD?

It is correct to write both Ph.D. and PhD. Which one is best to use depends on where you are in the world. In Great Britain, they tend to use Ph.D. In the United States of America, they prefer to use Ph.D.

Should I Write Ph.D. Or PhD?

What Does Ph.D. Or PhD Stand For?

Let’s try to understand what Ph.D. stands for.

It stands for two things. And it doesn’t stand for one or the other, it stands for both of them at the same time.

The first thing is “Doctor of Philosophy” and the second is “Philosophiae Doctor”. As the eagle-eyed among you may have noticed, “Philosophiae” is not English. It’s in Latin.

This goes back to the days when the only people who needed university were high thinkers and philosophers.

Why Americans And Brits Disagree On Ph.D. Or PhD

This could help us to understand why Brits prefer PhD but Americans prefer Ph.D.

Perhaps, according to the Brits, it stands for “Philosophiae Doctor”. But, according to the Americans, it stands for “Doctor or Philosophy”.

After all, the Brits do have a habit of trying to sound smarter. But, whichever one you use, people on both sides should know what you’re saying.

Why Ph.D. Or PhD Is A Bit Strange

Now, I want you all to understand how strange it is to call anyone with a PhD a “doctor of Philosophy”.

Let’s say someone gets a Ph.D. in history.

Well, first of all, is she really a doctor? If you break your leg, she’s not the first person you’ll go to for help.

But not only that, she studied history, not philosophy. So, she’s called a doctor of philosophy despite not being a doctor and not having studied history.

Yet, for some reason, we still call her a “Doctor of philosophy”.

Where Does The Word “Doctor” Come From?

When most of us hear the word “Doctor”, we think of someone who makes us better when we’re sick. And there may be a few of you who think of a skinny man who travels through time in a Police Box.

But originally, “Doctor” was Latin for teacher. Through time, you were able to get a “PhD” in more things than just philosophy.

And, if you wanted to become what we think of as a “Doctor”, you would need to have a “doctorate” in medicine.

Technically, “Doctor” would be the wrong word. But it’s become so common, it’s managed to “common” itself enough to become the right word.

How To Get A Ph.D. Or PhD

Now I’m afraid you can’t just walk into a university and walk out with a PhD. There are steps you need to take before you get there.

First of all, you will need to do a Bachelor’s degree. This is the degree you do when you first enter university. There are some jobs where a bachelors is enough.

Let’s be honest here, most of the time you spend doing a bachelor is just having fun.

If you want to, you can then progress onto doing a master’s degree. This is a bit more high level, and you tend to need to work for it.

Once you have your bachelors you may decide to go on to get a PhD. If you go for this, you will be officially able to call yourself an intellectual.

What Kind Of Word Is Ph.D. Or PhD?

There are three ideas for what kind of word Ph.D. is. I’ll tell you all of them and let you make up your own mind.

A PhD is something you have. You work towards it, and once you’ve handed in all of your papers, you get a PhD.

A PhD is also something you are. If you have a PhD, you might say “I’m a PhD.”

It can also be a title, similar to “Sir” or “OBE”.

If your name is James Smith, and you are PhD, your name and title could be, Mr James Smith PhD.

How To Address Someone With A Ph.D. Or PhD

Talking of this man called James Smith, there are several ways to address and introduce him.

  • If you have a Ph.D., you are allowed to call yourself “Doctor” even if you don’t have a PhD in medicine. Therefore, if he wants, James could be called Dr Smith.
  • Maybe he doesn’t want to be confused for a medical doctor but still wants to show off his Ph.D. In that case, we can call him James Smith PhD.
  • But, like many with a Ph.D., he may not want to mention it unless it’s important. If he’s one of these people, we should just call him Mr Smith.

Ph.D. Or PhD Vs Doctorate

Asking “What’s the difference between a PhD and a doctorate?” is a bit like asking what the difference is between an apple and a fruit.

Just like an apple is a kind of fruit, a PhD is a kind of doctorate. However, it’s not the only doctorate there is.

Here are some forms of doctorate you may want to know.

Doctor of philosophy. But now also means Doctor of something there isn’t a doctorate for.

Doctorate in business.

Doctorate in engineering.

Doctorate in education

Doctor of medicine.

If you were wondering whether you should write “PhD” or “Ph.D.”, you can write either, both are grammatically correct, and both are very common terms that mean the same thing.

The only slight difference is that “PhD” is more common in England and “Ph.D.” is more common in America. This is perhaps because the British believe it stands for “philosophiae doctor” but Americans see it as “Doctor of Philosophy”.

But, no matter whether you use “PhD” or “Ph.D.”, to have one, you neither need to be a doctor nor study philosophy. All you need to do is stay in university for long enough to be able to get yourself a PhD. Then, you can become a PhD, and your title will be PhD.

Frequently asked questions

What is a phd.

A PhD, which is short for philosophiae doctor (doctor of philosophy in Latin), is the highest university degree that can be obtained. In a PhD, students spend 3–5 years writing a dissertation , which aims to make a significant, original contribution to current knowledge.

A PhD is intended to prepare students for a career as a researcher, whether that be in academia, the public sector, or the private sector.

Frequently asked questions: Graduate school

In the US, most graduate school applications require you to include:

  • Transcripts from previous educational institutions
  • Standardized test scores (such as the GRE or MCAT)
  • A graduate resume
  • 2–3 letters of recommendation
  • A statement of purpose

Some programs may ask you to write a personal statement in addition to, or instead of, a statement of purpose. You may also be asked to an interview .

Always carefully read the application instructions for the specific program you’re applying to.

Most medical school programs interview candidates, as do many (though not all) leading law and business schools.

In research programs, it depends—PhDs in business usually do, while those in economics normally do not, for example.

Some schools interview everyone, while others only interview their top candidates. Look at the websites of the schools you’re applying to for more information on whether they conduct interviews.

In addition to thinking about your answers for the most commonly asked grad school interview questions , you should reach out to former and current students to ask their advice on preparing and what sort of questions will be asked.

Look back through your resume and come up with anecdotes that you could use for common questions, particularly those that ask about obstacles that you overcame. If you’re applying for a research program, ensure that you can talk about the previous research experience you’ve had.

You should also read as much research in your field as possible. Research the faculty at the schools you’re applying to and read some of their papers. Come up with a few questions that you could ask them.

Graduate schools often ask questions about why you are interested in this particular program and what you will contribute.

Try to stay away from cliche answers like “this is a good program” or “I got good grades in undergrad” and focus instead on the unique strengths of the program or what you will bring to the table. Understand what the program is looking for and come up with anecdotes that demonstrate why you are a good fit for them.

Different types of programs may also focus on different questions:

  • Research programs will often ask what topics you’d like to research and who you would like to work with, as well as specific questions about your research background.
  • Medical schools are interested in your personal motivation, qualities such as integrity and empathy, and how you’d respond to common ethical dilemmas.
  • Business schools will focus on your past work experience and future career prospects, and may be particularly interested in any experience you have managing or working with others.

Some students apply to graduate school straight from undergrad, but it’s also common to go back to school later in life. The ideal time to do so depends on various financial, personal, and career considerations . Graduate school is a big commitment, so you should apply at a time when you can devote your full attention to it.

Your career path may also determine when you should apply. In some career fields, you can easily progress without a graduate degree, while in others—such as medicine, business, and law—it’s virtually impossible to move up the career ladder without a specific graduate degree.

Most graduate school applications for American graduate programs are due in December or January for a September start.

Some types of programs, especially law school, are rolling applications, meaning that the earlier you apply, the earlier you’ll hear back. In this case, you should aim to apply as early as possible to maximize your chances.

Medical school follows a completely separate timeline with much earlier deadlines. If you’re applying for medical school, you should speak to advisors at your university for more information.

A good starting point to aim for is about 18 months before you would start the program, or 6–9 months before the applications are due.

In the first few months of the process, research programs and study for any standardized exams you might need.

You can then begin writing your personal statements and statements of purpose , as well as contacting people to write your letters of recommendation . Ensure that you give recommenders plenty of time to complete their letters (ideally around 2–4 months).

In the US, the graduate school application process is similar whether you’re applying for a master’s or a PhD . Both require letters of recommendation , a statement of purpose or personal statement , a resume or CV , and transcripts. Programs in the US and Canada usually also require a certain type of standardized test—often the GRE.

Outside the US, PhD programs usually also require applicants to write a research proposal , because students are expected to begin dissertation research in the first year of their PhD.

A master’s degree usually has a higher upfront cost, but it also allows you to start earning a higher salary more quickly. The exact cost depends on the country and the school: private universities usually cost more than public ones, and European degrees usually cost less than North American ones. There are limited possibilities for financial aid.

PhDs often waive tuition fees and offer a living stipend in exchange for a teaching or research assistantship. However, they take many years to complete, during which time you earn very little.

This depends on the country. In the United States, you can generally go directly to a PhD  with only a bachelor’s degree, as a master’s program is included as part of the doctoral program.

Elsewhere, you generally need to graduate from a research-intensive master’s degree before continuing to the PhD.

This varies by country. In the United States, PhDs usually take between 5–7 years: 2 years of coursework followed by 3–5 years of independent research work to produce a dissertation.

In the rest of the world, students normally have a master’s degree before beginning the PhD, so they proceed directly to the research stage and complete a PhD in 3–5 years.

A master’s is a 1- or 2-year graduate degree that can prepare you for a variety of careers.

All master’s involve graduate-level coursework. Some are research-intensive and intend to prepare students for further study in a PhD; these usually require their students to write a master’s thesis . Others focus on professional training for a specific career.

It’s best to ask in person if possible, so first reach out and request a meeting to discuss your graduate school plans.

Let the potential recommender know which programs you’re applying to, and ask if they feel they can provide a strong letter of recommendation . A lukewarm recommendation can be the kiss of death for an application, so make sure your letter writers are enthusiastic about recommending you and your work!

Always remember to remain polite. Your recommenders are doing you a favor by taking the time to write a letter in support of your graduate school goals.

This depends on the program that you are applying for. Generally, for professional programs like business and policy school, you should ask managers who can speak to your future leadership potential and ability to succeed in your chosen career path.

However, in other graduate programs, you should mostly ask your former professors or research supervisors to write your recommendation letters , unless you have worked in a job that corresponds closely with your chosen field (e.g., as a full-time research assistant).

Choose people who know your work well and can speak to your ability to succeed in the program that you are applying to.

Remember, it is far more important to choose someone who knows you well than someone well-known. You may have taken classes with more prominent professors, but if they haven’t worked closely with you, they probably can’t write you a strong letter.

The sections in your graduate school resume depend on two things: your experience, and the focus of the program you’re applying to.

Always start with your education. If you have more than one degree, list the most recent one first.

The title and order of the other sections depend on what you want to emphasize. You might include things like:

  • Professional experience
  • Voluntary and extracurricular activities
  • Publications
  • Awards and honors
  • Skills and certifications

The resume should aim for a balance between two things: giving a snapshot of what you’ve done with your life so far, and showing that you’re a good candidate for graduate study.

A resume is typically shorter than a CV, giving only the most relevant professional and educational highlights.

An academic CV should give full details of your education and career, including lists of publications and presentations, certifications, memberships, grants, and research projects. Because it is more comprehensive, it’s acceptable for an academic CV to be many pages long.

Note that, outside of the US, resume and CV are often used interchangeably.

No, don’t include your high school courses and grades. The education section should only detail your college education.

If you want to discuss aspects of high school in your graduate school application, you can include this in your personal statement .

A resume for a graduate school application is typically no more than 1–2 pages long.

Note, however, that if you are asked to submit a CV (curriculum vitae), you should give comprehensive details of all your academic experience. An academic CV can be much longer than a normal resume.

Always carefully check the instructions and adhere to any length requirements for each application.

If you’re applying to multiple graduate school programs, you should tailor your personal statement to each application.

Some applications provide a prompt or question. In this case, you might have to write a new personal statement from scratch: the most important task is to respond to what you have been asked.

If there’s no prompt or guidelines, you can re-use the same idea for your personal statement – but change the details wherever relevant, making sure to emphasize why you’re applying to this specific program.

If the application also includes other essays, such as a statement of purpose , you might have to revise your personal statement to avoid repeating the same information.

The typical length of a personal statement for graduate school applications is between 500 and 1,000 words.

Different programs have different requirements, so always check if there’s a minimum or maximum length and stick to the guidelines. If there is no recommended word count, aim for no more than 1-2 pages.

A statement of purpose is usually more formal, focusing on your academic or professional goals. It shouldn’t include anything that isn’t directly relevant to the application.

A personal statement can often be more creative. It might tell a story that isn’t directly related to the application, but that shows something about your personality, values, and motivations.

However, both types of document have the same overall goal: to demonstrate your potential as a graduate student and s how why you’re a great match for the program.

  • Not Just a PhD: The Other Types of Doctorate

Written by Mark Bennett

What to expect in this guide

Are you intrigued by the world of academia and considering pursuing a doctorate? If so, you may be wondering about the different types of doctorates available, how they differ from each other, and most importantly, which one is the right fit for you. In this guide we cover:

  • the various types of doctorates, from a PhD to a Doctor of Medicine (MD) and a Doctor of Education (EdD);
  • the differences between the doctorates as some are research-based like a PhD, while others are professional doctorates like an MD or EdD;
  • how to find the right fit for you by looking at your career aspirations, your passion for research or professional practice, and your academic strengths.

Studying a PhD isn't the only way to earn a doctorate. A doctorate can be an academic degree or a professional degree. In addition to the PhD there are several types of other doctorate , perhaps not as well-known – but just as prestigious. As a prospective student, you may have to make a decision between a PhD or an alternative 'professional' or 'practice' doctorate. Which is right for you will depend on your experience, subject area, or career ambitions.

More information on professional doctorates is available here . Below is a short summary of the types of doctorates you may find around the world to help you with your initial investigations.

There are three types of doctorates: PhD equivalents, Professional Doctorates and Higher degrees.

PhD equivalent degrees

There are several degrees which are equivalent to a PhD but have a different title, such as:

  • Doctor of Science (DSc): USA , Japan , South Korea , Egypt.
  • Doctor of Juridical Science and Doctor of the Science of Law: USA .
  • Dr. rer. nat. or Doctor rerum naturalium ('Doctor of the things of nature'): Germany .
  • Doktor Nauk (Doctor of Science): Poland , Russia.
  • Doctor of Theology: USA .
  • Doctorate by dissertation: Japan .

All of the above are academic research degrees equivalent to a UK PhD . It gets complicated because some of these degree titles, such as the Doctor of Science, can be used in other countries to designate 'higher degrees'. Higher degrees (see below), are awarded in recognition of a significant and original contribution to knowledge over a sustained period. Work submitted for a higher degree is expected to be of international calibre (University of Edinburgh definition).

Professional doctorates/ PhD by practice

The term 'professional doctorate' is itself a matter of debate. These doctorates can also be referred to as taught , by practice or industrial .

There are broadly two types of 'professional' doctorates:

1) Those providing qualifications for professional registration

Numerous fields of study, notably (but not exclusively) medicine and allied health professions have professional doctorates. For example; those working in dentistry, optometry, pharmacy, psychology, physical therapy, occupational therapy, and health science usually require such degrees for professional registration.

2) Those which are a professional development qualification

A professional development qualification will provide the holder with the ability to apply for more senior positions in their field, as well as in academia, but is not necessarily required for professional registration such as Doctorate of Education (EdD).

Professional doctorates have been around in the UK since the early 1990s, although some more established doctoral programmes have also been brought under the professional doctorate umbrella. The aim of these programmes is to find novel approaches to integrating professional and academic knowledge. According to the UK Economic & Social Research Council (ESRC), students undertaking a professional doctorate are expected to:

".... make a contribution to both theory and practice in their field, and to develop professional practice by making a contribution to (professional) knowledge."

There is a good definition comparing industrial PhDs and EngD on the website of the Centre for Innovation Manufacturing in Composites at the University of Nottingham:

“ PhD research can vary from abstract/theoretical to applied industry research. EngD research usually concerns a topic related to the business activities of the industrial sponsor. All time spent on EngD programmes are recognised by relevant institutions as contributing towards Chartered Engineer (CEng) status. ”

The EngD is mainly a UK doctorate, but there are similar doctorates such as the European Industrial Doctorate (funded by the European Commission Marie Curie Actions). EIDs are joint-doctoral training projects between an academic participant and a company established in two different EU Member States.

Creative PhDs can be awarded by practice, portfolio or composition in disciplines which include music, film, theatre, architecture or design. These degrees are called 'Doctor of Arts' in the USA and Canada .

They generally carry additional requirements (University of East Anglia definition):

  • The quality of the candidate's practice as submitted.
  • The merit of the associated written commentary.
  • The candidate's critical understanding of wider contexts for their practice, including creative, curatorial, educational, media studies, or film and TV business contexts; whether contemporary or historical.
  • The original contribution made by the submission both to an enhanced professional practice by the candidate and to its wider context in practice-based research and theory.

Higher degrees

Higher degrees are awarded in recognition of a substantial body of original research undertaken over the course of many years over and above that of a PhD.

Typically, the candidate will submit a collection of work which has been previously published in a peer-refereed context and pay an examination fee. The university assembles a committee of academics, both internal and external; who review the work submitted and decide whether the candidate deserves the doctorate based on the submission. It is not to be mixed up with the standard PhD requirements in the Netherlands (which tends to consist of thesis made up of three or four papers, minimum).

Most universities restrict candidacy to graduates or academic staff of several years standing. The most common doctorates of this type are those in Divinity (DD), Law (LLD), Civil Law (DCL), Music (DMus or MusD), Letters (DLitt or LittD), Science (DSc or ScD) and DSc (Med). Some institutions may also award a doctorate by publication to individuals fulfilling the conditions above, but who do not have a PhD already.

In some European countries such as Germany , such an award (also called habilitation or Privatdozent ) is used during recruitment of senior academics to demonstrate independent and thorough research, experience in teaching and lecturing and, more recently, the ability to generate funding within the area of research.

Higher degrees are often awarded honoris causa (the usual requirements, such as matriculation, residence, study and the passing of examinations, are waived) and are known as honorary degrees.

What's higher than a PhD?

As we've covered above, some universities do award higher degrees to recognise academic achievements that surpass those required for a PhD. However, these are honorary qualifications that are generally restricted to candidates who have contributed orginal research to their field over a number of years. A PhD is therefore still the highest standard academic qualification available.

PhD graduates may also decide to apply for a postdoctoral fellowship – these are not degrees, however, but fixed-term research positions designed to prepare you for an academic career.

PhD or Ph.D? Which is correct?

PhD and Ph.D are both correct ways to indicate the title, or honorific, of a doctor. However, Ph.D isn’t nearly as common as PhD. In fact, Ph.D is an old-fashioned method of writing it. But, there’s nothing wrong with using it that way. However, it’s more visually correct and recognizable in the modern world as PhD.

So, while there aren’t really any rules to remember for using PhD or Ph.D, it’s important to understand what it means. Plus the history of it will give you a little trivia.

Ph.D History

The earliest known documented use of Ph.D is from 1869. It’s an abbreviation of the Latin phrase, “Philosophiae Doctor” or “Doctor of Philosophy.” But “Philosophiae” has roots in ancient Greek, which translates into “love of wisdom.” To call someone a “doctor” is another way to say “learned person.”

The title PhD is the more common version in modern times and it means the same thing. These are people who receive doctorate degrees, which is the highest level of education someone can get. As it was back in 1869, the placement of the honorific can be before or after a name.

Examples of both PhD and Ph.D

The examples below show the myriad of ways in how to use and where to place PhD or Ph.D as an honorific for a person.

Dr. Ken Wellington, PhD

Professor Cynthia Kline, PhD

In many cases, doctors will have other degrees of study alongside their doctoral education. These additional honorifics indicate that.

Are you ready to discover your college program?

Considering a college degree? First, you’ll have to understand the types of degrees and college degree levels.

Different degrees prepare you for different career paths. For example, you can’t become a psychologist with just a bachelor’s degree — you’d need a master’s or doctorate in psychology. And you usually can’t become an engineer without at least a bachelor’s degree.

Typically, as your university degree level rises, your earning potential increases, and the unemployment rate decreases. That’s one more reason it’s important to understand the different types of degrees.

What Types of Degrees Are There in College?

There are many types of degrees you can earn in college. College degree levels can be broken down into two categories: undergraduate degrees and graduate degrees.

Here are the college degrees in order, from lowest ranking to highest:

  • Associate degree (undergraduate)
  • Bachelor’s degree (undergraduate)
  • Master’s degree (graduate)
  • Doctoral degree (graduate)

While a doctorate is the highest education level, some fields may stop at a master’s. The phrase “terminal degree” refers to the highest degree in a field.

A professional degree is a type of graduate degree — often a doctorate — that prepares you for a professional career in fields like law and medicine.

Associate Degree

  • Typical Program Length: 1-2 years
  • Typical Number of Credits: 60

Most associate degrees prepare you to enter the workforce immediately upon graduation. These programs can be found at community and technical colleges and typically last 1-2 years.

An associate degree can also serve as the foundation for a bachelor’s program. You may even be able to transfer some of the credits you earned for your associate degree toward a four-year degree.

Some associate degrees require you to complete an internship or practicum in addition to taking classes. This is particularly common among healthcare and tech degrees.

To apply for an associate degree program , you’ll need a high school diploma or equivalent, like a GED certificate. Some schools may require you to submit standardized test scores, such as the ACT or the SAT, as well.

Featured Associate Programs

What can you do with an associate degree.

An associate degree prepares you for vocational, allied health, and support roles. For example, you can become a medical assistant , paralegal , or vet tech with an associate degree.

The highest-paying careers with an associate degree pay over $80,000 per year. See the table below for salary information on other popular associate degree jobs.

Frequently Asked Questions About College Degree Levels

What are the four types of college degrees.

The four types of college degrees are associate degrees, bachelor’s degrees, master’s degrees, and doctoral degrees. Colleges classify associate and bachelor’s degrees as undergraduate degrees and master’s and doctoral degrees as graduate degrees.

Within those categories, you can earn many types of degrees. For instance, at the bachelor’s level, you could earn a bachelor of arts (BA), a bachelor of science (BS), or a bachelor of fine arts (BFA) degree.

What is a four-year college degree called?

A four-year college degree is called a bachelor’s degree. Another term for this degree type is a baccalaureate degree.

Many careers require a bachelor’s degree for entry-level roles. For example, most careers in business require you to hold a bachelor’s degree. Many roles in tech, education, the public sector, and engineering also require you to have a four-year degree.

Some career paths require a specific major. In many states, you’ll need a bachelor of science in nursing (BSN) to become a registered nurse . In other fields, your specific major matters less than the quality of your skills.

What is the highest degree?

The highest degree is a doctorate, also called a doctoral degree. In terms of university degree levels, both master’s and bachelor’s degrees rank below doctorates.

You can earn a doctorate in a wide array of fields, including the social sciences, business, the humanities, education, engineering, and healthcare.

In some fields, however, a master’s degree represents the terminal, or highest, degree. For instance, a master of fine arts (MFA) is the terminal degree for creative writing.

What is the hardest college degree?

Most would agree that the hardest college degree is a doctorate. As the highest education level, a doctorate requires significant expertise in the field.

Many Ph.D. programs take six years or more and require you to write a book-length dissertation based on original research.

Because a doctorate represents the top of the university degree levels, it’s a relatively uncommon degree. Only around 2% of U.S. adults held a doctorate in 2022, according to the U.S. Census Bureau .

What is the quickest degree?

The fastest degree you can get is either a one-year associate degree or a one-year master’s degree. While other types of degrees typically take a minimum of two years, you can earn a master’s degree in one year with an accelerated or fast-track program.

You can sometimes add a master’s degree to your bachelor’s through a 4+1 program, also known as a bachelor’s-to-master’s program. In this case, some of your coursework counts toward both your undergraduate and graduate degrees, meaning you’ll spend an additional year in college to leave with a master’s degree.
