• What is a PhD?

Written by Mark Bennett

A PhD is a doctoral research degree and the highest level of academic qualification you can achieve. A PhD involves students taking on independent and significant research culminating in a publishing-worthy thesis. The degree normally takes between three and four years of full-time work towards an original contribution to your subject.

This page explains what a PhD is, what it involves and what you need to know if you’re considering applying for a PhD research project , or enrolling on a doctoral programme .

On this page

The meaning of a phd.

The PhD can take on something of a mythic status. Are they only for geniuses? Do you have to discover something incredible? Does the qualification make you an academic? And are higher research degrees just for people who want to be academics?

Even the full title, ‘Doctor of Philosophy’, has a somewhat mysterious ring to it. Do you become a doctor? Yes, but not that kind of doctor. Do you have to study Philosophy? No (not unless you want to) .

So, before going any further, let's explain what the term 'PhD' actually means and what defines a doctorate.

What does PhD stand for?

PhD stands for Doctor of Philosophy. This is one of the highest level academic degrees that can be awarded. PhD is an abbreviation of the Latin term (Ph)ilosophiae (D)octor. Traditionally the term ‘philosophy’ does not refer to the subject but its original Greek meaning which roughly translates to ‘lover of wisdom’.

What is a doctorate?

A doctorate is any qualification that awards a doctoral degree. In order to qualify for one you need to produce advanced work that makes a significant new contribution to knowledge in your field. Doing so earns you the title 'Doctor' – hence the name.

So, is a PhD different to a doctorate? No. A PhD is a type of doctorate .

The PhD is the most common type of doctorate and is awarded in almost all subjects at universities around the world. Other doctorates tend to be more specialised or for more practical and professional projects.

Essentially, all PhDs are doctorates, but not all doctorates are PhDs.

Do you need a Masters to get a PhD?

Not necessarily. It's common for students in Arts and the Humanities to complete an MA (Master of Arts) before starting a PhD in order to acquire research experience and techniques. Students in Science, Technology, Engineering and Mathematics (STEM) don't always need an MS/MSc (Master of Science) to do a PhD as you'll gain training in lab techniques and other skills during your undergraduate degree.

Whether a Masters is a requirement for a PhD also varies by country. Australian PhDs may require a Masters as the equivalent of their own 'honours year' (where students work on research). US PhD programmes often include a Masters.

We have a whole guide dedicated to helping you decide whether a PhD without a Masters is the right route for you.

The origin of the PhD

Despite its name, the PhD isn't actually an Ancient Greek degree. Instead it's a much more recent development. The PhD as we know it was developed in nineteenth-century Germany, alongside the modern research university.

Higher education had traditionally focussed on mastery of an existing body of scholarship and the highest academic rank available was, appropriately enough, a Masters degree.

As the focus shifted more onto the production of new knowledge and ideas, the PhD degree was brought in to recognise those who demonstrated the necessary skills and expertise.

The PhD process – what's required to get a PhD?

The typical length of a PhD is three to four years full-time, or five to six years part-time.

Unlike most Masters courses (or all undergraduate programmes), a PhD is a pure research degree. But that doesn’t mean you’ll just spend years locked away in a library or laboratory. In fact, the modern PhD is a diverse and varied qualification with many different components.

Whereas the second or third year of a taught degree look quite a lot like the first (with more modules and coursework at a higher level) a PhD moves through a series of stages.

A typical PhD normally involves:

• Carrying out a literature review (a survey of current scholarship in your field).
• Conducting original research and collecting your results .
• Producing a thesis that presents your conclusions.
• Writing up your thesis and submitting it as a dissertation .
• Defending your thesis in an oral viva voce exam.

These stages vary a little between subjects and universities, but they tend to fall into the same sequence over the three years of a typical full-time PhD.

The first year of a PhD

The beginning of a PhD is all about finding your feet as a researcher and getting a solid grounding in the current scholarship that relates to your topic.

You’ll have initial meetings with your supervisor and discuss a plan of action based on your research proposal.

The first step in this will almost certainly be carrying out your literature review . With the guidance of your supervisor you’ll begin surveying and evaluating existing scholarship. This will help situate your research and ensure your work is original.

Your literature review will provide a logical jumping off point for the beginning of your own research and the gathering of results . This could involve designing and implementing experiments, or getting stuck into a pile of primary sources.

The year may end with an MPhil upgrade . This occurs when PhD students are initially registered for an MPhil degree and then ‘upgraded’ to PhD candidates upon making sufficient progress. You’ll submit material from your literature review, or a draft of your research findings and discuss these with members of your department in an upgrade exam . All being well, you’ll then continue with your research as a PhD student.

PhDs in other countries

The information on the page is based on the UK. Most countries follow a similar format, but there are some differences. In the USA , for example, PhD students complete reading assignments and examinations before beginning their research. You can find out more in our guides to PhD study around the world .

The second year of a PhD

Your second year will probably be when you do most of your core research. The process for this will vary depending on your field, but your main focus will be on gathering results from experiments, archival research, surveys or other means.

As your research develops, so will the thesis (or argument) you base upon it. You may even begin writing up chapters or other pieces that will eventually form part of your dissertation .

You’ll still be having regular meetings with your supervisor. They’ll check your progress, provide feedback on your ideas and probably read any drafts your produce.

The second year is also an important stage for your development as a scholar. You’ll be well versed in current research and have begun to collect some important data or develop insights of your own. But you won’t yet be faced with the demanding and time-intensive task of finalising your dissertation.

So, this part of your PhD is a perfect time to think about presenting your work at academic conferences , gaining teaching experience or perhaps even selecting some material for publication in an academic journal. You can read more about these kinds of activities below.

The third year of a PhD

The third year of a PhD is sometimes referred to as the writing up phase.

Traditionally, this is the final part of your doctorate, during which your main task will be pulling together your results and honing your thesis into a dissertation .

In reality, it’s not always as simple as that.

It’s not uncommon for final year PhD students to still be fine-tuning experiments, collecting results or chasing up a few extra sources. This is particularly likely if you spend part of your second year focussing on professional development.

In fact, some students actually take all or part of a fourth year to finalise their dissertation. Whether you are able to do this will depend on the terms of your enrolment – and perhaps your PhD funding .

Eventually though, you are going to be faced with writing up your thesis and submitting your dissertation.

Your supervisor will be very involved in this process. They’ll read through your final draft and let you know when they think your PhD is ready for submission.

All that’s left then is your final viva voce oral exam. This is a formal discussion and defence of your thesis involving at least one internal and external examiner. It’s normally the only assessment procedure for a PhD. Once you’ve passed, you’ve done it!

Doing a PhD – what's it actually like?

You can think of the ‘stages’ outlined above as the basic ‘roadmap’ for a PhD, but the actual ‘journey’ you’ll take as a research student involves a lot of other sights, a few optional destinations and at least one very important fellow passenger.

Carrying out research

Unsurprisingly, you’ll spend most of your time as a PhD researcher… researching your PhD. But this can involve a surprisingly wide range of activities.

The classic image of a student working away in the lab, or sitting with a pile of books in the library is true some of the time – particularly when you’re monitoring experiments or conducting your literature review.

Your PhD can take you much further afield though. You may find yourself visiting archives or facilities to examine their data or look at rare source materials. You could even have the opportunity to spend an extended period ‘in residence’ at a research centre or other institution beyond your university.

Research is also far from being a solitary activity. You’ll have regular discussions with your supervisor (see below) but you may also work with other students from time to time.

This is particularly likely if you’re part of a larger laboratory or workshop group studying the same broad area. But it’s also common to collaborate with students whose projects are more individual. You might work on shorter projects of joint interest, or be part of teams organising events and presentations.

Many universities also run regular internal presentation and discussion groups – a perfect way to get to know other PhD students in your department and offer feedback on each other’s work in progress.

Working with your supervisor

All PhD projects are completed with the guidance of at least one academic supervisor . They will be your main point of contact and support throughout the PhD.

Your supervisor will be an expert in your general area of research, but they won’t have researched on your exact topic before (if they had, your project wouldn’t be original enough for a PhD).

As such, it’s better to think of your supervisor as a mentor, rather than a teacher.

As a PhD student you’re now an independent and original scholar, pushing the boundaries of your field beyond what is currently known (and taught) about it. You’re doing all of this for the first time, of course. But your supervisor isn’t.

They’ll know what’s involved in managing an advanced research project over three years (or more). They’ll know how best to succeed, but they’ll also know what can go wrong and how to spot the warning signs before it does.

Perhaps most importantly, they’ll be someone with the time and expertise to listen to your ideas and help provide feedback and encouragement as you develop your thesis.

Exact supervision arrangements vary between universities and between projects:

• In Science and Technology projects it’s common for a supervisor to be the lead investigator on a wider research project, with responsibility for a laboratory or workshop that includes several PhD students and other researchers.
• In Arts and Humanities subjects, a supervisor’s research is more separate from their students’. They may supervise more than one PhD at a time, but each project is essentially separate.

It’s also becoming increasingly common for PhD students to have two (or more) supervisors. The first is usually responsible for guiding your academic research whilst the second is more concerned with the administration of your PhD – ensuring you complete any necessary training and stay on track with your project’s timetable.

However you’re supervised, you’ll have regular meetings to discuss work and check your progress. Your supervisor will also provide feedback on work during your PhD and will play an important role as you near completion: reading your final dissertation draft, helping you select an external examiner and (hopefully) taking you out for a celebratory drink afterwards!

Professional development, networking and communication

Traditionally, the PhD has been viewed as a training process, preparing students for careers in academic research.

As such, it often includes opportunities to pick up additional skills and experiences that are an important part of a scholarly CV. Academics don’t just do research after all. They also teach students, administrate departments – and supervise PhDs.

The modern PhD is also viewed as a more flexible qualification. Not all doctoral graduates end up working in higher education. Many follow alternative careers that are either related to their subject of specialism or draw upon the advanced research skills their PhD has developed.

PhD programmes have begun to reflect this. Many now emphasise transferrable skills or include specific training units designed to help students communicate and apply their research beyond the university.

What all of this means is that very few PhD experiences are just about researching and writing up a thesis.

The likelihood is that you’ll also do some (or all) of the following during your PhD:

The work is usually paid and is increasingly accompanied by formal training and evaluation.

Conference presentation

As a PhD student you’ll be at the cutting edge of your field, doing original research and producing new results. This means that your work will be interest to other scholars and that your results could be worth presenting at academic conferences .

Doing this is very worthwhile, whatever your career plans. You’ll develop transferrable skills in public speaking and presenting, gain feedback on your results and begin to be recognised as an expert in your area.

Conferences are also great places to network with other students and academics.

Publication

As well as presenting your research, you may also have the opportunity to publish work in academic journals, books, or other media. This can be a challenging process.

Your work will be judged according to the same high standards as any other scholar’s and will normally go through extensive peer review processes. But it’s also highly rewarding. Seeing your work ‘in print’ is an incredible validation of your PhD research and a definite boost to your academic CV.

Public engagement and communication

Academic work may be associated with the myth of the ‘ivory tower’ – an insular community of experts focussing on obscure topics of little interest outside the university. But this is far from the case. More and more emphasis is being placed on the ‘impact’ of research and its wider benefits to the public – with funding decisions being made accordingly.

Thankfully, there are plenty of opportunities to try your hand at public engagement as a PhD student. Universities are often involved in local events and initiatives to communicate the benefits of their research, ranging from workshops in local schools to public lectures and presentations.

Some PhD programmes include structured training in order to help students with activities such as the above. Your supervisor may also be able to help by identifying suitable conferences and public engagement opportunities, or by involving you in appropriate university events and public engagement initiatives.

These experiences will be an important part of your development as a researchers - and will enhance the value of your PhD regardless of your career plans.

What is a PhD for – and who should study one?

So, you know what a PhD actually is, what’s involved in completing one and what you might get up to whilst you do. That just leaves one final question: should you do a PhD?

Unfortunately, it’s not a question we can answer for you.

A PhD is difficult and uniquely challenging. It requires at least three years of hard work and dedication after you’ve already completed an undergraduate degree (and probably a Masters degree too).

You’ll need to support yourself during those years and, whilst you will be building up an impressive set of skills, you won’t be directly progressing in a career.

But a PhD is also immensely rewarding. It’s your chance to make a genuine contribution to the sum of human knowledge and produce work that other researchers can (and will) build on in future. However obscure your topic feels, there’s really no such thing as a useless PhD.

A PhD is also something to be incredibly proud of. A proportionately tiny number of people go on to do academic work at this level. Whatever you end up doing after your doctorate you’ll have an impressive qualification – and a title to match. What’s more, non-academic careers and professions are increasingly recognising the unique skills and experience a PhD brings.

Other PhDs - do degree titles matter?

The PhD is the oldest and most common form of higher research degree, but a few alternatives are available. Some, such as the DPhil are essentially identical to a PhD. Others, such as the Professional Doctorate or DBA are slightly different. You can find out more in our guide to types of PhD .

Is a PhD for me?

There’s more advice on the value of a PhD – and good reasons for studying one – elsewhere in this section. But the following are some quick tips if you’re just beginning to consider a PhD.

Speak to your lecturers / tutors

The best people to ask about PhD study are people who’ve earned one. Ask staff at your current or previous university about their experience of doctoral research – what they enjoyed, what they didn’t and what their tips might be.

If you’re considering a PhD for an academic career, ask about that too. Are job prospects good in your field? And what’s it really like to work at a university?

Speak to current PhD students

Want to know what it’s like studying a PhD right now? Or what it’s like doing research at a particular university? Ask someone who knows.

Current PhD students were just like you a year or two ago and most will be happy to answer questions.

If you can’t get in touch with any students ‘face to face’, pop over to the Postgraduate Forum – you’ll find plenty of students there who are happy to chat about postgraduate research.

Take a look at advertised projects and programmes

This may seem like a strange suggestion. After all, you’re only going to study one PhD, so what’s the point of reading about lots of others?

Well, looking at the details of different PhD projects is a great way to get a general sense of what PhD research is like. You’ll see what different PhDs tend to have in common and what kinds of unique opportunity might be available to you.

And, with thousands of PhDs in our database , you’re already in a great place to start.

PhD admission requirements

Phd applications, can i apply for a phd without relevant qualifications, phds through mphil, starting a phd, alternatives to a phd, degrees higher than a phd.

Do you have a love of wisdom and a clear field of academic interest? If so, a PhD might be the right choice for you. But what is a PhD, and how can you get one?

PhD is short for Doctor of Philosophy. This is an academic or professional degree that, in most countries, qualifies the degree holder to teach their chosen subject at university level or to work in a specialized position in their chosen field.

The word ‘philosophy’ comes from the Ancient Greek philosophia , literally translated as ‘love of wisdom’. It originally signified an individual who had achieved a comprehensive general education in the fundamental issues of the present world. Today, the Doctor of Philosophy still requires a love of wisdom but applies to individuals who have pursued knowledge in a much more specialized field.     

A PhD is a globally recognized postgraduate academic degree awarded by universities and higher education institutions to a candidate who has submitted a thesis or dissertation, based on extensive and original research in their chosen field. The specificities of PhD degrees vary depending on where you are and what subject you’re studying.

In general, however, the PhD is the highest level of degree a student can achieve (with some exceptions). It usually follows a master’s degree, although some institutions also allow students to progress straight to a PhD from their bachelor’s degree. Some institutions also offer the opportunity to ‘upgrade’ or ‘fast-track’ your master’s degree to a PhD, provided you are deemed to possess the necessary grades, knowledge, skills and research abilities.

Traditionally, a PhD involves three to four years of full-time study in which the student completes a substantial piece of original research presented as a thesis or dissertation. Some PhD programs accept a portfolio of published papers, while some countries require coursework to be submitted as well.

Students must also complete a ‘viva voce’ or oral defense of their PhD. This can be with just a small number of examiners, or in front of a large examination panel (both usually last between one to three hours). While PhD students are traditionally expected to study on campus under close supervision, distance education and e-learning schemes have meant a growing number of universities are now accepting part-time and distance-learning PhD students. 

Generally speaking,   PhD admission requirements   relate to the candidate’s grades (usually at both bachelor’s level and master’s level) and their potential research capabilities. Most institutions require that candidates hold an honors degree or a master’s degree with high academic standing, along with a bachelor’s degree with at least upper second-class honors. In some cases, you can also apply for a PhD simply on the basis of your master’s degree grades. Grades-based PhD admission requirements may also be based on the type of funding you will be using – you may be able apply with lower grades if you self-fund your PhD (read more on PhD funding  here ).

Some institutions and subjects (such as psychology and some humanities and science subjects) stipulate that you must find a tenured professor in your chosen institution to serve as your formal advisor and supervisor throughout your PhD program before you can be formally accepted into the program. In other cases, you will be assigned a supervisor based on your research subject and methodology once you have been accepted into the PhD program.

Either way, it is a good idea to approach a faculty member in your chosen institution before applying for a PhD, in order for them to determine whether your research interests align well with the department, and perhaps even help you to brainstorm PhD research options.

Language proficiency

Some PhD applications require proof of proficiency in the language in which you intend to study. You can either provide the results of an approved standardized language exam or show evidence of having completed undergraduate or postgraduate study in the relevant language.

Employment/academic references

Some institutions may also ask for a record of your employment such as a résumé, and/or all your academic transcripts, including details of course modules and module content as part of your PhD application. Details of other research projects you have completed and any publications you have been featured in can also help your application.

Many PhD applicants are also asked to provide references from two or three people who know them well in an academic setting, such as their undergraduate or postgraduate tutors or professors. These references must have a particular focus on your academic performance, coursework and research abilities, your research potential and your interest in your chosen field of study.

Personal statements

Many institutions ask for a personal statement - a short essay which you can use to demonstrate your passion for your chosen subject. You can outline your reasons for wanting to study a PhD, personal motivations for doing so, any extracurricular activities that are particularly relevant or should be highlighted, and any flexibility in your chosen area(s) of research. If you need help, many institutions have a guide to personal statements on their website, which can also help you tailor your personal statement to each institution.

PhD research proposals

Finally, in order to be considered for a place on a PhD program, applicants are expected to submit a PhD research proposal. A research proposal:

• Outlines your proposed research topics in the context of previous work,
• Highlights your awareness of current debates within the field,
• Demonstrates a suitable level of analysis,
• Identifies relevant gaps in current knowledge,
• Suggests a relevant research hypothesis to fill some of these gaps,
• Explains your intended research methodology in sufficient detail,
• Discusses the implications to real-world policy that your PhD proposal may invite.

This will help admissions tutors to assess your aptitude for PhD research, and also to determine whether your research interests align with their own research priorities and available facilities. They will also consider whether they have the relevant staff to provide you sufficient supervisory expertise.

For this reason in particular, it is important to research institutions thoroughly before applying for a PhD. Not only will you be happier if your research interests fit in with those of your chosen institution, but institutions may be forced to reject your application simply on the basis of discrepancies between their research interests and yours. Note that this initial research proposal is not necessarily binding – it is usually a starting point from which to further develop your research idea.

Some subject areas (such as science and engineering) do not ask for original research proposals. Instead, the institution presents a selection of PhD research projects which are formulated by the supervisor(s) concerned and peer reviewed. This may be done at a certain time of year or year-round, depending on the institution. Students can then submit a statement demonstrating a clear understanding of the research to be undertaken and their suitability to undertake it.

These PhD research projects may also have been formulated in consultation with another organization that may provide funding/scholarships for the successful candidate. These pre-defined PhD projects are less common in arts, humanities and social sciences subjects, where it’s more common for students to submit their own proposals.

If you wish to do a PhD but do not have the relevant qualifications or their equivalent, you may still be able to apply for a PhD program by fulfilling additional requirements as stipulated by your institution of choice. Some possible requirements could be to undertake specified extra study or passing a qualifying examination.

You may also be able to make a special case to your chosen institution, either on the basis of a non-degree professional qualification and considerable practical experience, or on the basis of foreign qualifications. Special case PhD applications will require the strong backing of your potential supervisor, so you will need to seek his/her advice and support before applying in this manner.

Another option available for potential PhD candidates is to apply as a general research student or for an  MPhil degree . This is a common path taken by PhD candidates. The MPhil is an advanced master’s degree awarded for research and can be suitable for students who do not have a strong research background. You will be required to take some taught courses to get you up to speed with things like research methods.

The successful completion of a one-year taught program may lead to the award of the MRes degree, which includes more taught components than the MPhil and can be awarded in lieu of a PhD for students who have not completed the required period of study for a PhD. Alternatively, the successful completion of original research may lead to the award of the MPhil degree, which can be awarded without the candidate having to present a defense of their dissertation (a requirement to achieve a PhD).

If, after the first or second year of your research (i.e. during your MPhil), the institution is satisfied with the progress of your work, you may then be able to apply for full PhD registration. Usually, your supervisor or tutor will be in charge of determining whether you are ready to progress to a PhD. If you’re deemed to be ready, you will then need to develop a title for your thesis and choose your PhD program.

When registration has been completed you should be officially informed of: your supervisor(s) and their area(s) of expertise; the topic or field of PhD research for which you have been accepted; the minimum length of time required before submission of your thesis; the formal assessment methods preferred by the institution.

Most institutions will also provide you with a comprehensive list of provisions and available facilities for PhD and research students at the university. They will also include a detailed outline of the milestones you must reach on your journey to achieve a PhD. Your supervisor will be in charge of going through these milestones with you, making reports on your progress, and advising you on your next steps. You will need to make adequate progress each year in order to continue your PhD studies.

When looking for PhD programs, keep in mind that there are several types of degrees which have the term “doctor” in their title, such as the Juris Doctor (common in the US, Canada, Australia, Mexico and parts of Asia), the Doctor of Physical Therapy (DPT) or the Doctor of Pharmacy (DPharm) and the US and Canada version of the Doctor of Medicine (MD).

These degrees are generally not classified as PhDs as they lack that vital component that really defines the PhD: academic research. These other types of doctorate degrees are instead referred to as entry-level doctorate degrees. Candidates who wish to pursue a PhD may do so afterwards, and this may be known as a ‘post-professional doctorate’.

Neither the JD nor the US/Canada MD programs universally require students to complete a specified academic research component in order to be awarded the degree title. However, there are also many research degrees, such as the MD, which conduct scholarly research (medical in the case of the MD) which is published in peer-reviewed journals. This makes them very similar to PhDs, and some countries consider them equivalent. Some institutions therefore offer combined professional and research training degrees, such as the MD-PhD dual program, which is useful for medical professionals looking to pursue a research career.

In addition to various degrees which may be considered equivalent to a PhD, there are also some ‘higher doctorate’ courses considered to be a step above the Doctor of Philosophy (PhD). These are most common in UK universities and in some European countries, although they are increasingly awarded as honorary degrees. The US does not have a system of higher doctorates and offer the titles solely as honorary degrees. Honorary degrees are sometimes signified by adding ‘hc’ (for  honoris causa ) to the end of the degree title.

Some higher doctorate degrees include:

• Doctor of Science (DS/SD): Awarded in recognition of a substantial and sustained contribution to scientific knowledge beyond that required for a PhD.
• Doctor of Literature/Letters (DLit/DLitt/LitD): Awarded in recognition of achievement in the humanities or for original contribution to the creative arts.
• Doctor of Divinity (DD): Awarded above the Doctor of Theology (DTh), usually to recognize the recipient’s ministry-oriented accomplishments.
• Doctor of Music (DMus): Awarded in the UK, Ireland and some Commonwealth countries on the basis of a substantial portfolio of compositions and/or scholarly publications on music.
• Doctor of Civil Law (DCL): Highest doctorate excepting the DD, offered on the basis of exceptionally insightful and distinctive publications that contain significant and original contributions to the study of law or politics in general.

What is a PhD?

• Types of Doctorates
• A Doctor of Philosophy (PhD) is the highest globally recognized postgraduate degree that higher education institutions can award.
• PhDs are awarded to candidates who undertake original and extensive research in a particular field of study.
• Full time PhD programmes typically last three to four years, whilst part time PhD programmes typically last six to seven years.
• A PhD can lead to an academia teaching role or a career in research. A PhD can also equip you with skills suitable for a wide range of jobs unrelated to your research topic or academia.

Definition of a PhD – A Doctor of Philosophy (commonly abbreviated to PhD , Ph.D or a DPhil ) is a university research degree awarded from across a broad range of academic disciplines; in most countries, it is a terminal degree, i.e. the highest academic degree possible.

PhDs differ from undergraduate and master’s degrees in that PhDs are entirely research-based rather than involving taught modules (although doctoral training centres (DTCs) offer programmes that start with a year of lecture-based teaching to help develop your research skills prior to starting your project).

In most English-speaking countries, those that complete a PhD use the title “Doctor” (typically abbreviated to Dr) in front of their names and are referred to as such within academic and/or research settings. Those that work in fields outside of academia may decide not to use the formal doctor title but use post-nominal letters (e.g. John Smith PhD); it’s unusual though for someone to use both the Doctor title and post-nominal letters in their name.

PhD vs Doctorate

A PhD and a professional doctorate are both research-based terminal degrees.

However, where a PhD focuses on original research mostly around theoretical concepts, a professional doctorate focuses on examining existing knowledge to solve real-life, practical problems.

While there is much crossover between the two, a PhD is generally better suited for an individual to wants to advance the knowledge and understanding in their field, and a professional doctorate degree is better suited to a working professional who wants to better be able to apply knowledge and understanding to their field.

What Are the Entry Requirements for a PhD?

To be accepted on to a PhD programme, students usually need to hold at least a high ( 2:1 and above ) undergraduate degree that is related to the field of research that they want to pursue. A PhD candidate may also be expected to hold a Master’s degree , however, this does not mean you must have one, as it is still possible to enrol into a PhD without a Master’s .

Self-funded courses may sometimes be more relaxed in relation to entry requirements . It may be possible to be accepted onto a self-funded PhD programme with lower grades, though these students typically demonstrate their suitability for the role through professional work experience.

Whilst a distance learning project is possible , most PhD candidates will carry out their research over at least three years based at their university, with regular contact with two academic supervisors (primary and secondary). This is particularly the case for lab-based projects, however, some PhD projects require spending time on-site away from university (e.g. at a specialist research lab or at a collaborating institution abroad).

How Long Does a PhD Take?

Typically, full-time PhDs last 3-4 years and part-time PhDs last 6-7 years. However, at the discretion of the university, the thesis writing-up period can be extended by up to four years.

Although most doctoral programmes start in September or October, they are generally much more flexible than taught-courses and can start at any time of the year.

How Much Does a PhD Cost?

Tuition fees for UK and EU students vary between £3,000 and £6,000 per year, with the average tuition fee of £4,712 per year for 2023/24 programmes.

Tuition fees increase considerably for international students, varying between £16,000 to £25,000 per year, with an average tuition fee of £19,600 per year .

Nonetheless, most students will secure PhD funding in the form of studentships, scholarships and bursaries to help pay for these fees. These funding opportunities can either be partial, which cover tuition fees only, or full, which cover both tuition fees and living expenses.

UK national students can also apply for Doctoral Loans from Student Finance England if they are unable to secure funding.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

What Does a PhD Involve?

To be awarded a PhD, a doctoral student is required to produce a substantial body of work that adds new knowledge to their chosen field.

A PhD programme will typically involve four key stages:

Stage 1: Literature Review

The first year of a PhD involves attending regular meetings with your supervisors and carrying out a search on previously published work in your subject area. This search will be used to produce a literature review which should set the context of the project by explaining the foundation of what is currently known within the field of research, what recent developments have occurred, and where the gaps in knowledge are. In most cases, this will be an extension of your research proposal should you have produced one as part of your application. The literature review should conclude by outlining the overarching aims and objectives of the research project. This stage of setting achievable goals which are original and contribute to the field of research is an essential first step in a successful PhD.

The supervisor is the main point of contact through the duration of a PhD – but remember: they are there to mentor, not to teach, or do it for you . It will be your responsibility to plan, execute and monitor your own work as well as to identify gaps in your own knowledge and address them.

Stage 2: Research

The second year (and prehapse some of your third year) is when you work on your research. Having identified novel research questions from your review of the literature, this is where you collect your data to help answer these questions. How you do this will depend on the nature of your doctoral research: for example, you may design and run experiments in a lab alongside other PhD students or visit excavation sites in remote regions of the world. You should check in regularly with your supervisors to update them and run any ideas or issues past them.

Have the structure and chapters of your thesis in mind as you develop and tackle your research questions. Working with a view of publishing your work will be very valuable later on.

Stage 3: Write up of Thesis

The next key stage of a PhD is writing a doctoral thesis , which typically takes from anywhere between three months to one year. A thesis is a substantial body of work that describes the work and outcomes of the research over the previous two to three years. It should tell a detailed story of the PhD project – focusing on:

• The motivations for the research questions identified from the literature review.
• The methodologies used, results obtained, and a comprehensive analysis and discussion of the findings.
• A detailed discussion of the key findings with an emphasis on the original contributions made to your field of research and how this has been impactful.

There is no universal rule for the length of a PhD thesis, but general guidelines set the word count between 80,000 to 100,000 words.

For your thesis to be successful, it needs to adequately defend your argument and provide a unique or increased insight into your field that was not previously available.

Stage 4: Attending the Viva

A viva voce , most commonly referred to as just a ‘ viva ‘, is an interview-style examination where the PhD student is required to engage in a critical appraisal of their work and defend their thesis against at least two examiners. The examiners will ask questions to check the PhD student has an in-depth understanding of the ideas and theories proposed in their thesis, and whether they have developed the research skills that would be expected of them.

The viva is one of the final steps in achieving a PhD, and typically lasts at least two hours, but this duration can vary depending on the examiners, the university and the PhD project itself.

Once you have done the viva – you’re on the home stretch. You will typically be asked to make some amendments to your thesis based on the examiner’s feedback. You are then ready to submit your final thesis for either:

• PhD – If you pass the requirements you will be awarded a PhD degree (most common outcome),
• MPhil – If you failed to meet requirements for a PhD, you may be downgraded to an MPhil degree (uncommon outcome),
• Fail – No award is given, typically for cases of plagiarism (extremely uncommon outcome).

What Is It Like to Undertake a PhD?

We’re often asked what it is like to undertake a PhD study. Unfortunately, this isn’t a simple answer to this question as every research project is different.

To help give insight into the life of a PhD student, we’ve interviewed PhD students at various stages of their programmes and put together a series of PhD Student Interviews . Check out the link to find out what a PhD is like and what advice they have to offer you.

What Are the Benefits of A PhD?

A PhD is the highest globally recognised postgraduate degree that higher education institutions can award. The degree, which is awarded to candidates who demonstrate original and independent research in a particular field of study, is not only invaluable in itself, but sets you up with invaluable skills and traits.

Career Opportunities

First, a PhD prepares you for a career in academia if you wish to continue in this area. This takes form as a career in the Higher Education sector, typically as a lecturer working their way to becoming a professor leading research on the subject you’ve studied and trained in.

Second, a PhD also enables the opportunity for landing a job in a research & development role outside of the academic environment. Examples of this include laboratory work for a private or third sector company, a governmental role and research for commercial and industrial applications.

Transferable Skills

Finally, in possessing a PhD degree, you can show to employers that you have vital skills that make you an asset to any company. Three examples of the transferable skills that you gain through a PhD are effective communication, time management, and report writing.

• Communication – presenting your work in written and oral forms using journal papers and podium presentations, shows your ability to share complex ideas effectively and to those with less background knowledge than you. Communication is key in the professional environment, regardless of the job.
• Time management – The ability to prioritise and organise tasks is a tremendous asset in the professional industry. A PhD holder can use their qualification to demonstrate that they are able to manage their time, arrange and follow a plan, and stick to deadlines.
• Report writing – Condensing three years of work into a thesis demonstrates your ability to filter through massive amounts of information, identify the key points, and get these points across to the reader. The ability to ‘cut out the waffle’ or ‘get to the point’ is a huge asset in the professional industry.

Aside from the above, you also get to refer to yourself as a Doctor and add fancy initials after your name!

What Can I Do After a PhD?

One of the most desirable postdoctoral fields is working within independent Research and Development (R&D) labs and new emerging companies. Both industries, especially R&D labs, have dedicated groups of PhD graduates who lead research activities, design new products and take part in crucial strategic meetings. Not only is this a stimulating line of work, but the average salaries in R&D labs and emerging start-ups are lucrative. In comparison, an undergraduate with five years of experience within their given field will, on average, likely earn less than a new PhD graduate taking on a R&D position.

It’s a common misunderstanding that PhDs only opens the door for an academic career such as university lecturers and training providers. Although obtaining a PhD opens these doors, the opportunities extend far beyond educational roles. In fact, recent data from the UK’s Higher Education Statistics Agency (HESA) indicates only 23% of PhD graduates take a position in educational roles . This low percentage is primarily because PhD graduates have a wide range of skills that make them suitable for a broad spectrum of roles. This is being seen first hand by the increasing number of PhD graduates who are entering alternative roles such as research, writing, law and investment banking.

How Do I Find a PhD?

We appreciate that finding a PhD programme to undertake can be a relatively daunting process. According to Higher Education Student Statistics , over 22,000 PhDs were awarded in 2016/17 within the United Kingdom alone. Clearly there are a huge number of PhD programmes available. This can sometimes be confusing for prospective doctorates, particularly when different programmes are advertised in different places. Often, it is difficult to know where to look or where to even start. We’ve put together a list of useful sources to find the latest PhD programmes:

• A great place to start is with our comprehensive and up-to-date database of available PhD positions .
• Assuming you are still at university, speak to an existing PhD supervisor within your department.
• Attend as many postgraduate open days as you can. Whilst there, speak to current PhD students and career advisors to get an awareness of what PhDs are on offer.
• Visit the postgraduate section of university websites and the PhD Research Council section of the UKRI website.

What is a phd.

A PhD is the highest postgraduate qualification level that can be awarded in academic study. This is usually completed over three to four years of full-time study, and involves research into an original contribution in your chosen field. 

PhD is an acronym that stands for Doctor of Philosophy. The name for PhD comes from the Latin term “Philosophiae Doctor”, which roughly translates to “Lover of wisdom”.

Whether you’re finishing up from an undergraduate degree, on a masters course or even just looking to get back into education, you’ll have seen people talking about getting a PhD .

Most people know vaguely what a PhD is – it’s a university course that means you can call yourself ‘Doctor’ without having to do medicine, right? Whilst that is surprisingly close to the truth, we’re here to answer the oft-asked question of ‘what is a PhD?’.

This guide covers everything you need to know about a PhD.

What does a PhD involve?

A PhD will typically take three years to complete. If taken part time, then it will be separated into three different stages:

Year 1: This will involve you speaking with your advisor about your research ideas, finishing your research proposal and beginning to put deadlines in place for your research. You’ll also complete your literature review in this stage. During this, you’ll review the existing research done on the topic that you’re planning to research to help you determine the gaps in the research that you can target

Year 2: During this stage, you’ll begin to conduct your research to gather data. You’ll document this whole process for your thesis and begin to attend conferences where you will have the opportunity to present your current research to other professionals and researchers in the field. You can take this further and take steps to educate the public on the benefits of your research.

Year 3: The final stage of a PhD involves using the data you’ve collected and the documentation of your research to write your thesis. You may still be conducting research at this point, and that’s OK. Once you’ve finished your thesis, you’ll justify your research and decisions in a viva .

How long is a PhD?

A typical PhD will take three to four years to complete when studying full time. Studying part time can take up to six years. The good news is that the thesis can be extended by up to four years. This means that if you haven’t gotten anywhere near finishing your research by the end of the second year, you can apply to extend your thesis and continue your research for up to four more years. Many PhD students will complete their thesis in the 4th year.

How is a PhD different from other degrees?

To start with, describing a PhD as a university course can be a bit misleading. Whilst it is a course offered by a university, it’s incredibly different to most courses. Unlike the undergraduate level, you won’t be covering your subject broadly you’ll be focused on one very particular area. Whilst a masters degree, especially a research one, may be focused, it won’t be nearly as focused as a PhD.

That said – don’t expect this focused level of research to necessarily be groundbreaking! Though part of doing a PhD is the intent to produce original research, it’s also primarily there to train your research skills and to prove yourself as a capable researcher.

A PhD is research focused

One of the main differences between PhDs and other types of postgraduate degree is that PhDs are heavily research based. PhDs involve a lot of independent research time, where you'll study your topic in detail using academic resources – such as the university's online library and online materials. This format is different to taught postgraduate degrees, which involve a lot more taught aspects such as lectures and seminars.

Do you need a masters to study a PhD?

In order to study a PhD, you’ll need to have a masters degree and a bachelors degree with a 2:1 or higher. Though self-funded students and students with professional experience in the field may be admitted with lower grades

Some students may begin with a MPhil (Masters of philosophy) or a Mres ( Master of research) and upgrade to a PhD by the end of their studies.

Where can I study a PhD?

Most universities offer PhD programs across a variety of disciplines. It is possible to study a PhD at almost any university and in almost any subject. Since a PhD is an independent research-based program, there is a lot of flexibility in regard to what you’ll study. 

PhD students often choose their own study topics and carry out independent research into that topic. This makes it possible to study your intended PhD at almost any university. 

Although, it is important to check which specific subject areas the university specialises in. For instance, if a university specialises in linguistics, then it would be a good idea to complete a linguistics PhD at that university as opposed to one that specialises in another subject.

It can be difficult to find the perfect course at the right university. That’s why we’ve put together advice on how to find a PhD .

It’s important to remember that a PhD is different from a typical university course. Rather than going to lectures, you’ll be conducting independent research, and so the application process will be quite different. Learn how to apply for a PhD  with our expert guide.

A PhD means attending ‘optional’ lectures and conferences

PhDs do involve some aspects of taught study, including lectures and conferences, although these are often optional and take place less often than on lower level courses.

Now of course, the university doesn’t just accept you, your project and tell you to have fun. You’ll work with a supervisor, and there will be conferences, lectures, and other such things that you can attend. Unlike lower level courses, however, although you won’t necessarily be examined on these things that doesn’t mean you shouldn’t go! Conferences are a great way to meet people, get your name out and network . For any career, but especially one in academia, networking is well worth it.

A PhD is a high standard qualification

But what does having a PhD show, other than the fact you spent three to four years working on research and can now call yourself Dr [Your surname here]? 

A PhD is a globally recognised, high standard qualification. This means that if you choose to move elsewhere in the world, your PhD will be recognised as a credible postgraduate qualification.

In addition, a PhD can open up a whole world of new job opportunities! This includes academic roles , such as postdoctoral research posts, or even possibly fellowships. 

Regardless of which career path you choose to take, a PhD is regarded as the highest level postgraduate qualification – reflecting your impressive work ethic, knowledge, and workplace skills.

How to get a PhD

Getting a PhD is not easy by any means. But, if it’s something you truly want to do, it’s well worth it. So let’s take a look at just how to get a PhD!

Choose your research area

Before getting started with your PhD, you want to make sure you know what area you’d like to do it in. Don’t just pick something on a whim – this is something you’re going to be studying for the next four years of your life, and something that, once you finished your PhD, you’ll have your name attached to. So, for arts and humanities students, find an area of your subject that fascinates you enough that you’ll want to spend the next few years writing about it. For scientists, find an area you’d be happy to be working on in a team, and wouldn’t mind moving into as a career!

Find a good supervisor

Once you’ve selected your topic, it’s time to start looking for a supervisor . Depending on what you’re currently doing, asking tutors for contacts or recommendations can be well worthwhile, but if you can’t do this, check out what research your potential supervisor has done. 

In addition, try and arrange an in-person meeting – or at least, a phone conversation. Email can make communication difficult and given this is the person you’ll be working under for the foreseeable future, you want to ensure you get on.

Then, assuming you’re accepted and have appropriate funding, you’ll be considered a probationary PhD student . At the end of your first year, you’ll be expected to prove you’re capable of the full course, so you’ll be tested in the form of writing a report. Once you pass this, you’re good to go!

Your next few years will be spent attending conferences, working on the research and your thesis. Your thesis will talk about what you’ve spent your time doing, how you dealt with any difficulties that arose, and generally show what your contribution to your subject is! Once that’s out the way, you get the fun job of having a viva – that is, talking about your thesis to a bunch of academics.

Pass the viva? Then you’ve succeeded.

So that’s how to get a PhD!

UK Research Councils

There are a selection of UK Research Councils, each of whom are part of the  UK Research and Innovation (UKRI) organisation. Collectively, these UK research councils provide an average of £380 million in PhD studentship funding every year – acting as the largest PhD funding body in the UK. 

Here’s an overview of UK research councils:

• Science and Technology Facilities Council
• Arts and Humanities Research Council
