meaning of thesis viva

• PhD Viva Voces – A Complete Guide
• Doing a PhD
• A PhD viva involves defending your thesis in an oral examination with at least two examiners.
• The aim of a PhD viva is to confirm that the work is your own , that you have a deep understanding of your project and, overall, that you are a competent researcher .
• There are no standard durations, but they usually range from one to three hours, with most lasting approximately two hours .
• There are six outcomes of a PhD viva: (1) pass without corrections (2) pass subject to minor corrections, (3) pass subject to major corrections, (4) downgrade to MPhil with no amendments, (5) downgrade to MPhil subject to amendments, (6) immediate fail.
• Almost all students who sit their viva pass it, with the most common outcome being ‘(2) – pass subject to minor corrections’.

What Is a PhD Viva?

A viva voce , more commonly referred to as ‘viva’, is an oral examination conducted at the end of your PhD and is essentially the final hurdle on the path to a doctorate. It is the period in which a student’s knowledge and work are evaluated by independent examiners.

In order to assess the student and their work around their research question, a viva sets out to determine:

• you understand the ideas and theories that you have put forward,
• you can answer questions about elements of your work that the examiners have questions about,
• you understand the broader research in your field and how your work contributes to this,
• you are aware of the limitations of your work and understand how it can be developed further,
• your work makes an original contribution, is your own and has not been plagiarised.

Note: A viva is a compulsory procedure for all PhD students, with the only exception being when a PhD is obtained through publication as opposed to the conventional route of study.

Who Will Attend a Viva?

In the UK, at least two examiners must take part in all vivas. Although you could have more than two examiners, most will not in an attempt to facilitate a smoother questioning process.

One of the two examiners will be internal, i.e. from your university, and the other will be external, i.e. from another university. Regardless, both will be knowledgeable in your research field and have read your thesis beforehand.

In addition to your two examiners, two other people may be present. The first is a chairperson. This is an individual who will be responsible for monitoring the interview and for ensuring proper conduct is followed at all times. The need for an external chairperson will vary between universities, as one of the examiners can also take on this role. The second is your supervisor, whose attendance is decided upon by you in agreement with your examiners. If your supervisor attends, they are prohibited from asking questions or from influencing the outcome of the viva.

To avoid any misunderstandings, we have summarised the above in a table:

Note: In some countries, such as in the United States, a viva is known as a ‘PhD defense’ and is performed publicly in front of a panel or board of examiners and an open audience. In these situations, the student presents their work in the form of a lecture and then faces questions from the examiners and audience which almost acts as a critical appraisal.

How Long Does a Viva Last?

Since all universities have different guidelines , and since all PhDs are unique, there are no standard durations. Typically, however, the duration ranges from one to three hours, with most lasting approximately two hours.

Your examiners will also influence the duration of your viva as some will favour a lengthy discussion, while others may not. Usually, your university will consult your examiners in advance and notify you of the likely duration closer to the day of your viva.

What Happens During a Viva?

Regardless of the subject area, all PhD vivas follow the same examination process format as below.

Introductions

You will introduce yourselves to each other, with the internal examiner normally introducing the external examiner. If an external chairperson is present, they too are introduced; otherwise, this role will be assumed by one of the examiners.

Procedure Explained

After the introductions, the appointed chair will explain the viva process. Although it should already be known to everyone, it will be repeated to ensure the viva remains on track during the forthcoming discussion.

Warm-Up Questions

The examiners will then begin the questioning process. This usually starts with a few simple opening questions, such as asking you to summarise your PhD thesis and what motivated you to carry out the research project.

In-Depth Questions

The viva questions will then naturally increase in difficulty as the examiners go further into the details of your thesis. These may include questions such as “What was the most critical decision you made when determining your research methodology ?”, “Do your findings agree with the current published work?” and “How do your findings impact existing theories or literature? ”. In addition to asking open-ended questions, they will also ask specific questions about the methodology, results and analysis on which your thesis is based.

Closing the Viva

Once the examiners are satisfied that they have thoroughly evaluated your knowledge and thesis, they will invite you to ask any questions you may have, and then bring the oral examination to a close.

What Happens After the Viva?

Once your viva has officially ended, your examiners will ask you to leave the room so that they can discuss your performance. Once a mutual agreement has been reached, which can take anywhere from 10 minutes to an hour, you will be invited back inside and informed of your outcome.

PhD Viva Outcomes

There are six possible outcomes to a viva:

• Immediate award of degree: A rare recommendation – congratulations, you are one of the few people who completely satisfied your examiners the first time around. You do not have to do anything further at this point.
• Minor amendments required: The most common recommendation – you obtain a pass on the condition that you make a number of minor amendments to your thesis, such as clarifying certain points and correcting grammatical errors. The time you have to make these changes depends on the number of them, but is usually one to six months.
• Major amendments required: A somewhat uncommon recommendation – you are requested to make major amendments to your thesis, ranging from further research to collecting more data or rewriting entire sections. Again, the time you have to complete this will depend on the number of changes required, but will usually be six months to one year. You will be awarded your degree once your amended thesis has been reviewed and accepted.
• Immediate award of MPhil: An uncommon recommendation – your examiners believe your thesis does not meet the standard for a doctoral degree but meets the standard for an MPhil (Master of Philosophy), a lower Master’s degree.
• Amendments required for MPhil: A rare recommendation – your examiners believe your thesis does not meet the standard for a doctoral degree, but with several amendments will meet the standard for an MPhil.
• Immediate fail: A very rare recommendation – you are given an immediate fail without the ability to resubmit and without entitlement to an MPhil.

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

What Is the Pass Rate for Vivas?

Based on an  analysis of 26,076 PhD students  who took their viva exam between 2006 and 2017, the PhD viva pass rate in the UK is 96%; of those who passed, about 80% were required to make minor amendments to their thesis. The reason for this high pass rate is that supervisors will only put their students forward for a viva once they confidently believe they are ready for it. As a result, most candidates who sit a viva are already well-versed in their PhD topic before they even start preparing for the exam.

How Do I Arrange a Viva?

Your viva will be arranged either by the examiners or by the chairperson. The viva will be arranged at least one to two months after you have submitted your thesis and will arrange a viva date and venue that is suitable for all participants.

Can I Choose My Examiners?

At most universities, you and your supervisor will choose the internal and external examiners yourselves. This is because the examiners must have extensive knowledge of the thesis topic in order to be able to examine you and, as the author of the thesis in question, who else could better determine who they might be than you and your supervisor. The internal examiner is usually quite easy to find given they will be from your institution, but the external examiner may end up being your second or third preference depending on availability.

Can I Take Notes Into a Viva?

A viva is about testing your competence, not your memory. As such, you are allowed to take notes and other supporting material in with you. However, keep in mind that your examiners will not be overly impressed if you constantly have to refer to your notes to answer each question. Because of this, many students prefer to take an annotated copy of their thesis, with important points already highlighted and key chapters marked with post-it notes.

In addition to an annotated copy of a thesis, some students also take:

• a list of questions they would like to ask the examiners,
• notes that were created during their preparation,
• a list of minor corrections they have already identified from their viva prep work.

How Do I Prepare for a PhD Viva?

There are several ways to prepare for a PhD viva, one of the most effective being a mock viva voce examination . This allows you to familiarise yourself with the type of viva questions you will be asked and identify any weak areas you need to improve. They also give you the opportunity to practise without the pressure, giving you more time to think about your answers which will help to make sure that you know your thesis inside out. However, a mock viva exam is just one of many methods available to you – some of the other viva preparation methods can be found on our “ How to Prepare for a PhD Viva ” page.

How the viva process works

The viva is a long-established part of the examination process for a research degree. The main focus of the assessment is on the written thesis/dissertation (and other outputs, for a Practice as Research students). However, the viva, which is the oral part of the assessment, is used to inform the examiners’ final assessment decision.

The viva gives the examiners the opportunity to explore any issues in detail and provide inspiring advice for your future research career. Examiners may have a strong sense of the outcome from reading the thesis, but the viva gives you an opportunity to defend your work, as well as to validate the thesis and demonstrate your skills in participating in academic discussion with research colleagues.

Viva arrangements

Your department is responsible for nominating two examiners: one internal and one external, whose names must be approved by the Faculty Dean (Postgraduate).

The internal examiner is expected to undertake any arrangements necessary for conducting the viva. You’ll then be contacted to confirm the arrangements for the examination of the thesis, including the date and time of the viva.

The viva should be held no later than two months after your examiners receive your thesis for examination unless exceptional circumstances prevent it from happening. In the case of a staff candidate, the department must nominate two external examiners, rather than an internal and an external, and an Independent Chair is appointed to oversee the examination process.

Students who fail to engage in viva arrangements, to the extent where it has not been possible to conduct a viva, shall be deemed to have withdrawn permanently from the University.

Viva format

Two formats are available as standard viva examination formats of the University: Video Link Vivas and In-Person Vivas. The availability of both video link vivas and in-person vivas means that the most appropriate format can be sought, to support any individual needs and adjustments appropriately, including cultural and/or interpersonal challenges.

Video Link Vivas provide the ability to expand the network of external examiners internationally as potential barriers, such as financial constraints, time commitments and our environmental efforts to reduce our carbon footprint, are removed. There are both financial and time-saving benefits for all viva attendees, including candidates, who will not have to bear the costs of returning to campus for their viva.

The diverse nature of some thesis and viva formats (including, but not limited to, Practice as Research examinations) are potentially not well-suited to the video link format, so this should be considered when deciding on the viva format.

In advance of the thesis submission, students should discuss with their supervisor which examination format is most appropriate and preferred. Where possible, the department will look to accommodate a student’s preference, and will liaise with the examination team before making a decision.

Venue (in-person vivas)

In cases where the viva is taking place in-person, the venue for the viva should normally be on campus, reasonably quiet and allow the viva to proceed without interruption.

The Faculty Dean (Postgraduate)’s approval is required for a viva to be held at a venue outside the University of Essex or one of its Partner Institutions.

Technical preparation (video-link vivas)

The University recommends the use of Zoom as its preferred and supported video- conferencing software. The Graduate Administrator within each Department/School will be responsible for arranging the Zoom meeting, and wherever possible a University video- conferencing room should be used.

Technical assistance will be provided by Audio Visual Services as required. This will include practical advice on the protocols of communication by video link. Time should be allowed before the start of the viva to ensure the software and equipment is working correctly, and that all parties are satisfied with the arrangement.

Who attends?

The viva will normally only involve the internal examiner, the external examiner and the student.

The Faculty Dean (Postgraduate) may appoint an Independent Chair, who is a senior member of the Academic or Research staff of the University of Essex, to oversee the conduct of the oral examination in line with the Policy for the Appointment of Independent Chairs for Research Degree Vivas  (.pdf).

The student’s supervisor can only be present in exceptional circumstances, approved on an individual basis by the Faculty Dean (Postgraduate) and with the agreement of the external examiner.

The length of a viva will vary but if it is longer than two hours the internal examiner will recommend an adjournment for a break.

If you feel the need for a break earlier than two hours, please feel free to inform the examiners. Any breaks taken will not affect the outcome of the viva.

Discussion between examiners

Once you’ve submitted your thesis and the examiners have been appointed, copies of the thesis/dissertation and examination paperwork are sent to the examiners by the Postgraduate Research Education Team.

The examiners must not contact each other to discuss their assessment of your thesis, nor engage in discussion with you ahead of the viva, except for when making logistical arrangements. On the day of the viva and before seeing the student, the examiners will have a pre-viva meeting at which they discuss their initial assessment and agree the approach to the viva, including the areas of questioning.

It is the responsibility of the internal examiner to oversee the proceedings at the viva and to ensure that the University’s Principal Regulations for Research Degrees are adhered to, unless an Independent Chair has been appointed.

The start of the viva

At the start of the viva, the internal examiner will introduce the examination team, confirm the purpose of the viva, and explain how the viva will proceed. If there is anything you’re unsure of, now is a good time to ask.

Questioning

Remember, no one is perfect. There will be strengths and weaknesses to your research and your examiners will want to explore these in more detail.

Normally, the examiners will start with some general/introductory questions that will ease you into discussing your thesis and research. These will be followed by a discussion of strengths and weaknesses of the thesis. It will be an opportunity for you to demonstrate your abilities of self-analysis and reflection, exploring things you’d do differently in future and what you’ve learnt during the process.

The examiners will be asking questions to provide clarification, and seek explanation and elaboration where appropriate. Please remember that each examiner has a different style, and some questions may appear quite direct and challenging. In this situation, it’s important to stay relaxed and take your time to give a thoughtful response.

If you are asked a question which you don’t understand, feel free to ask for clarification.

Reaching a decision

Once the viva has finished, you’ll be asked to leave the room, whilst the examiners reach a conclusion about the recommended result. The result will be one which is listed in the University’s Principal Regulations for Research Degrees .

You’ll then be invited back into the room to be told the recommended result and the reasons for the decision. If corrections are required, you’ll be sent a written list of corrections after the viva.

The Oral Examination (viva) - Doctoral degrees, MSc, MLitt, MPhil by Thesis

What is a viva.

The viva (short for viva voce) is an oral examination which gives the opportunity for:

• you to defend your thesis and clarify any matters raised by your examiners
• the examiners to probe your knowledge in the field
• the examiners to assure themselves that the work presented is your own and to clarify matters of any collaboration
• the examiners to come to a definite conclusion about the outcome of the examination

Your examiners will determine if you meet the requirements for award of the research degree  for which you are a candidate.

Preparation

Talk to your supervisor and/or Academic Adviser for guidance on how to prepare for your viva.

The Quality Assurance Agency for Higher Education (QAA) has produced a series of videos to help PGR students prepare for their viva. Note that the procedures for examination at the University of Cambridge may be different to those referred to by other Higher Education Institutions featured in the videos.

You will have been told the identity of your examiners. This will normally be one examiner internal to the University of Cambridge and one external examiner, but you may have two external examiners. The Degree Committee may also appoint an Independent Chair to be present during your viva and/or additional examiner(s). Your examiners will be in touch to make arrangements for your viva .  If you have not been advised of the date for your viva within six weeks of submitting your thesis, you should contact your Degree Committee.

Location of the viva

The viva will normally take place in-person in Cambridge, but you may choose to be examined remotely by video conference. You should inform your Degree Committee of your preference when you notify them of your intention to submit/apply for appointment of examiners. Please also make your supervisor aware of your preference as it may affect the choice of available examiners.

Arrangements where you and one examiner are co-located in Cambridge, with the second examiner participating by video conference, where both examiners are co-located and you participate by video conference, or where you and the examiners are all in separate locations, are permissible provided all parties agree.

In-person oral examination:  In-person examinations may be delayed depending on the availability of the examiners as travel time will need to be factored in. Students who are overseas and returning to Cambridge for their viva should contact the International Student Office for visa advice if their Student visa has expired or will be expiring soon.

Video conference oral examination: A guide to conducting vivas by video conference can be found here .

The choice of in-person or video conference viva does not constitute procedural irregularity grounds for complaint should you fail the examination.

Adjustments to the oral examination on the grounds of disability

If you wish to notify examiners of a disability or request adjustments on account of a disability for your viva (either your first year assessment or final examination), you can do this via your Degree Committee by completing and submitting the voluntary disclosure form . It is recommended you do this at least four weeks before your expected date of examination to allow time for appropriate recommendations and adjustments to be made. 

Once you have submitted the form, your Degree Committee will contact the University’s Accessibility and Disability Resource Centre (ADRC) who will advise them on the appropriate course of action. The ADRC may contact you if additional information is required or to provide you with an offer of additional support.

The information provided on the voluntary disclosure form will be kept confidential and will not be used for any other purpose.

If you already have a Student Support Document (SSD) that includes recommendations for adjustments to the viva, and you have given permission for this to be shared with the Degree Committee, you do not have to complete the voluntary disclosure form but may do so if you wish.

There is no specific dress code. You can wear whatever you feel comfortable in.

What can I take in to my viva?

You may take the following into your viva:

• A copy of your thesis (the same as the one you submitted)
• plain paper or blank notebook and a pen/pencil for taking notes or sketching ideas
• a presentation in the form specified by your Examiners – your Examiners will advise you in advance if a presentation is required
• any other provision that is agreed in advance with the Degree Committee as a reasonable adjustment for disability

What happens at the viva?

• It is carried out between yourself and the two examiners and is conducted in English
• An Independent Chairperson may attend if the Degree Committee requires this
• There is no set duration, but a viva will normally last between 90 minutes and three hours
• You may be required to do a presentation - please check with your Department whether this is the case. If you are required to give a presentation, you should be informed at least two weeks in advance of the viva
• The viva cannot be recorded
• Your supervisor cannot attend the viva

Your Department should advise on any department-specific conventions or procedures.

Possible outcomes of the viva

The possible outcomes are:

• Conditional approval - pass without correction (but for doctoral degrees subject to submission of hardbound and electronic copies of the thesis ); or pass, subject to minor or major corrections 
• Revision and resubmission of the thesis for a fresh examination
• [Doctoral examination only] Revision and resubmission of the thesis for a fresh examination or acceptance of the MSc/MLitt without further examination (but possibly subject to corrections)
• [Doctoral examination only] Not to be allowed to revise the thesis, but approved for the MSc/MLitt without further revision or examination (but possibly subject to corrections)
• [Doctoral examination only] Revision and resubmission of the thesis for examination for the MSc/MLitt degree
• Outright failure

Notification of the result of the viva

Your examiners are asked not to give any direct indication of the likely outcome of the examination as the official result of examination can be confirmed only by the Postgraduate Committee or by Student Registry acting on its behalf. The Degree Committee will forward their decision to the Student Registry who will notify you of the outcome and email your reports to you, copying in your Supervisor. For the MPhil by Thesis, the Degree Committee will confirm the outcome and notify you of this.

What PhD Students Should Know About the PhD Viva

The viva voce, usually referred to solely as a 'viva', is an oral test during which a PhD candidate defends their PhD thesis in front of a panel of examiners. (In the USA, it is called a 'defense'.) It is common in the UK, US, and many other countries. The phrase 'viva voce' literally translates to 'with living voice'. For many students, the viva can be a thing of dread. After all, standing before a group of accomplished academics in your field and justifying your work and results can be intimidating. It is also an opportunity, however, to share your work, explore new perspectives, and network with experts. If you are preparing for your viva, you are probably wondering how to put your best foot forward. We’ve rounded up some tips aimed at helping you make the most of the viva experience.

• Student Tips

If you are preparing for your viva, you are probably wondering how to put your best foot forward. We’ve rounded up some tips aimed at helping you make the most of the viva experience.

Before Your Viva...

Understand the process.

Depending on the institution, viva policies and practices may vary. Knowing what to expect can help you feel more comfortable and prepared.

Generally speaking, there will be a minimum of two examiners: at least one internal examiner, who is usually the chair, and one external examiner, who is from another institution. Your PhD supervisor may also be present, if everyone agrees.

The process typically begins with polite introductions with the chair clarifying that the viva is a “focused discussion” as opposed to an interrogation. The chair will usually review the process and procedures, as well. Most vivas will then progress to a simple 'warm-up' question. For example, you may be asked to provide a brief introduction to your work and key findings. Then, the examiners will move on to more in-depth material.

Vivas range in length, but usually span between one and four hours. It’s important to remember that no two vivas are alike. However, all vivas should speak to both your motivation and your contribution.

Know what your examiners are looking for.

When you’re caught up in viva preparations, it’s easy to lose sight of the bigger picture: Why you did a PhD in the first place, and what’s it’s all about? Before getting overwhelmed by your viva, remind yourself that a PhD is about knowing your field, making a useful contribution to it, mastering appropriate techniques and understanding their limitations, communicating knowledge in a professional way, and making something your own . A thoughtful viva should reflect these elements of the PhD, which is exactly what your examiners are looking for.

Anticipate what questions you’ll be asked.

Knowing what your examiners are looking for also offers useful insights into what questions you’ll be asked. Common topics for discussion include: what original contributions your thesis has made to the field of study; the main research questions you were hoping to address; the strengths and weaknesses of your thesis; what you might do differently if you had to start over; how you would proceed from the project if money wasn’t an issue; and what your plans are for the future. Some of these questions will be easier than others. Experts recommend arranging a mock viva to practice your answers in advance, taking time to vocalize them, if possible.

Revisit your thesis -- thoroughly.

Writing a thesis is a marathon. While the last thing you may want to do at this point is revisit it in its entirety, going over it line by line can help you feel more prepared and confident. Annotate and highlight text as you go so you can find important results when called on to do so.

Familiarize yourself with your examiners’ work.

Your viva may be about your thesis, but you will be surrounded by academics who bring unique backgrounds and perspectives to the table. By looking into their academic profiles and learning about their own research, you can derive a better understanding of their motivations and possible viewpoints. This can offer insight into the types of questions they might ask. It’s also important to keep up on all related research in the field.

During Your Viva...

Bring supporting materials -- but know them nonetheless.

Most vivas are “open-book,” meaning you can bring reference materials with you. In addition to a copy of your thesis, other materials to bring may include your list of anticipated questions and answers, printouts of the results of any post-submission experiments, notebooks you have kept along the way, and any other resources pertaining to either your research, thesis, or questions you may be asked.

Take your time.

Listen carefully to every question you’re asked, and don’t rush to answer them. If you don’t understand a question, ask for clarification. Keep answers as succinct and relevant as possible; avoid tangents. Answers may require calling upon a range of examples and domains. Remember: the viva tests not only your depth of knowledge, but also your breadth of knowledge. If, after giving it serious consideration, you really can’t answer a question, be honest about it.

Know what NOT to do.

Knowing what not to do is just as important as knowing what to do during your viva. Some things to avoid: Dogmatism, defensiveness, and long-windedness. While confidence is good, confidence to the point of overconfidence (ie., appearing blase or laid-back) can be detrimental.

Try to enjoy it.

PhD graduate Michael James Heron told The Guardian , “The best advice I ever got was ‘Try to enjoy it’. It seemed ludicrous at the time, but I actually found myself really getting into the discussion as the viva went on. It’s one of the earliest chances you get to talk to someone who not only informed your research (ideally) but is also conversant with your own. It’s a great chance to explore the contours of your research – treat it as such, and it doesn’t seem quite so daunting.”

After Your Viva…

Prepare to celebrate...and to rewrite, if necessary.

One more piece of good news about vivas? You won’t have to wait long for the results! After your viva is finished, you’ll be asked to withdraw from the room so the examiners can deliberate. And while several outcomes are possible with varying degrees of success and failure, it’s important to keep in mind that the vast majority of PhD candidates who go through the viva process do gain their degrees... ...However, in the majority of cases, examiners will decide to award the degree subject to the 'satisfactory completion of minor or major amendments' (or similar phrasing - each institution has its own regulations about viva outcomes). In the UK, most students pass their viva 'with minor corrections'. This situation can, unsurprisingly, bring about mixed emotions. On the one hand, you have 'passed' your PhD; on the other hand, there is yet more work to do (the deadline for these corrections is determined on a case-by-case basis, but is usually some months).

"Let’s be clear: getting through your viva ‘with minor corrections’ is a great achievement," writes Dr Mary Frank, who holds a PhD in Translation Studies from the University of Bristol, UK, in a post for Thesis Whisperer. However, she explains that she was simply "burned out" from her studies and had "nothing left to give". "While my supervisors cracked open a bottle of bubbly after the viva and people started gathering to congratulate me, I found it hard to celebrate," she adds. "My brain felt completely drained, yet I knew that I somehow had to address those corrections before I could pass the finishing post. To my examiners and supervisors, those corrections were indeed ‘minor’, but to me they seemed bewildering and daunting."

But she got through it! She advises others to view the viva as a key milestone in the PhD journey but possibly not the final one, and, when tackling corrections, to distance yourself from your thesis and imagine yourself as an editor looking critically at somebody else's work. Meanwhile, Vitae, an organization for the professional development of researchers, advises PhD candidates to take notes during their viva and write them up immediately, meet with your main supervisor to go over the changes required, and analyze the examiners' report carefully.

Do this, and you can enjoy that bubbly fully -- as a fully-fledged Doctor of Philosophy !

Thesis, Viva, and Corrections ¶

All PGRs must produce a thesis, which describes in full detail the wider context of the research field including a literature review, the motivation for the research, the research which was carried out, an evaluation of the results, and a discussion of the contribution made to the field by the research and what should be done in the future. This needs to be submitted by three days before the end of the fourth year. For the relevant University policies, see ‘Policies’ Chapter.

There are two formats in which the thesis can be produced: traditional format and alternative format. Traditional format is probably what most people imagine a thesis is like, a very substantial report presented as a self-contained exposition. The alternative format thesis “… allows a postgraduate doctoral or MPhil student to incorporate sections that are in a format suitable for submission for publication in a peer-reviewed journal.” Presentation of Thesis Policy 2 . The alternative format thesis is often thought of as a collection of publications, with a short commentary associated with each one, tying the works into a unifying thread, or “thesis”.

Which you use is a decision you will need to make with your supervisor .

The advantages of the alternative format thesis are that if you already have several papers, you can more easily produce a thesis out of them. Also, if you have plans to write several papers, you can write your thesis in such a way that it will be easier to facilitate these plans, because writing the thesis will be build around writing papers. The papers can be submitted after the thesis.

The disadvantage of the alternative format is that it is less widely used in the UK, so many supervisors and examiners may be less comfortable with it.

A Q&A on the Alternative Format Thesis 1 can be found here . Note that it says in Section 4,

“…it may not be until year 2 or 3 that you feel you are in a position to use the alternative format.”

but it says in Section 5 that a request must be made in writing by the end of year 2. Thus, if you are considering using alternative format, apply for it by the end of year 2 . You can revert to traditional format without asking permission formally.

Plagiarism ¶

All PGRs should make sure they are familiar with what the university expects from its PGRs. All PGRs are also required to complete a plagiarism course.

In view of the serious consequences of plagiarism and academic malpractice, it is essential that all PGRs familiarise themselves with the accepted format for referencing work in their discipline, and that they start using the accepted form as soon as possible.

Ignorance of the proper format, or ignorance of the definitions of plagiarism and academic malpractice used by the university, is not a valid defence against a possible claim of plagiarism or other instance of academic malpractice.

Writing Advice ¶

Whichever format you choose, you must give yourself sufficient time to produce the thesis. You must know yourself, and how quickly you are able to write. Six months is a minimum time for most people. Some may need nine.

Be sure to leave enough time in your planning to write the thesis. Most people take between 6 and 8 months, depending on how quickly they write and how much of the writing already exists in papers and reports. Your supervisor can give you advice on how to write the thesis. It’s a good idea to use the LaTeXstyle 3 file for University of Manchester Thesis format.

Do not feel that you need to write it in order; start with the easiest parts first. Usually the technical sections on the research done by you are the easiest, because you know them well. The literature review may be next easiest. The introduction is usually the hardest to write, and many advise that it be written last.

The University COVID 19 Statement below can be included.

COVID Statement ¶

Acknowledging the impact of COVID-19 on postgraduate research programmes: guidance for PGRs, Supervisors and Examiners on inclusion of a COVID-19 impact statement with theses submitted by PGRs at the University of Manchester.

The University of Manchester recognises that the COVID-19 pandemic, and consequent closure of our campus (18 th March 2020) and national and international lockdowns, has directly or indirectly impacted the work of many of our postgraduate researchers (PGRs). Although the campus began re-opening from mid-June 2020, some researchers will be disrupted until all campus research facilities are open, and operational at adequate capacity, fieldwork can resume safely and/or personal circumstances become more manageable.

Many of our PGRs have been/will be able to accommodate the disruption to their research plans by changing the scope, phasing or design or their project; others have/will have circumstances that necessitate an extension to programme or to the thesis submission date.

We encourage PGRs who wish to make their Examiners aware of the impact COVID-19 has had on their research plans and thesis to prepare an Impact Statement for consideration during the examination process.

The University recommends that Examiners take the Impact Statement into account when assessing the thesis, and PGR at viva, albeit without compromising standards as set out in the University’s ordinances and the QAA’s expectations of doctoral outcomes , which emphasise that doctoral degrees should be awarded based on the quality, rather than quantity, of research undertaken and the candidate’s acquisition of intellectual and practical competencies.

Examiners should use their academic judgment when deciding whether, as set out in the Examinations of Doctoral Degrees Policy , the following criteria have been met:

the candidate possesses an appropriate knowledge of the particular field of learning within which the subject of the thesis falls; the research which is reported in the thesis contributes a substantial addition to knowledge; the results of the research show evidence of originality and independent critical judgement; the thesis is presented in a lucid and scholarly manner; the thesis and the work reported in it are the candidate’s own;

whilst bearing in mind that they should judge the ‘ substantial addition to knowledge ’ in relation to what can be reasonably expected within a period of study (3, 3.5 or 4yrs FT) that has been conducted in the context of disruption caused by COVID-19.The Impact Statement should include the following information:

Details on how disruption caused by COVID-19 has impacted the research (for example, an inability to collect/analyse data as a result of travel restrictions/restricted access to labs/additional caring and health responsibilities - 500 words maximum); A description of how the planned work would have fitted within the thesis’ narrative (e.g. through method development, development of analytical skills or advancement of hypotheses - 500 words maximum); A summary of any decisions / actions taken to mitigate for any work or data collection/analyses that were prevented by COVID-19 (500 words maximum).

PGRs are encouraged to discuss the statement with their supervisory team before submitting the statement within the thesis presented for examination and should refer to section 6.3 in the Presentation of Theses Policy for details.

Thesis Writing Advice ¶

Sage advice from Prof Bill Buchanan OBE, PhD, FBCS - Professor at Edinburgh Napier University:

Say up-front what the problem is, what other people have done, and how you have added to it. The Introduction chapter is the most important chapter of all, and you need to grab the reader, and tell them what the problem is, and how you have solved it. If the examiner understands the thesis after the Introduction, you are half way there. I’ve read a few thesis’ where I had no idea what the point was until I actually got to the end, and the contribution was revealed on the last page. This is a major gamble, as some readers may give up before that point, and not know the end contribution. Be fair on the reader and tell them the contribution, and keep telling them. Get rid of those typos! You wouldn’t believe the number of PhD thesis’ I have read that have a typo in the very first line of the thesis. A reader becomes annoyed if they have to keep correcting typos, and the more annoyed the reader, the more time they are taking away from actually reading the content. Try and start off on a good footing, so that the Abstract and Introduction chapter have been read over several times - typically talking them out loud. If possible get someone else to read the Introduction, and see if they understand what the point of work is. Bad grammar shows bad practice and a weak supervision. Part of doing a PhD is learning how to write and present ideas, and how to review and edit. One of the most important things that you learn in a PhD is how to write, so that others can understand your ideas. A good part of this is for supervisors to get involved reading the work, and in giving detailed feedback. It is often a good idea for supervisors to mark up early drafts with red pen, so that PGRs get an idea on the amount of checking and editing that is often required. Superlatives are not very good! A PhD is a scientific study, and the usage of superlatives should be avoided, along with weak words like “big” … “the measure gives a very big number”. If a number is large, define what large actually means, as everything is relative. Significance matters. I’ve read thesis’ that draw a graph, and then gives me values of 10 decimal places, and then to be told that there is an importance of one thing to another. But is it significant? If I move from 100.01254632 to 100.1263241, is that a massive change and why do we need so many decimal places? Every measurement has an accuracy, and this should always be included in the presentation of the values. Examiners want to know the significance of something, and if it isn’t significant, then just tell them. One table tells much more than a whole lot of numbers. Again I’ve read so many thesis’, where the writer continually presents a whole series of numbers and graphs, and where they could all be moved into an appendix, and compiled into a single table (or graph). A good supervisor should be able to spot how to collapse lots series of tables into a single one, as they often have to do it for papers. Many PGRs rely on drawing graphics for presenting trends whereas tables are often better, especially in defining changes within the figures presented. A great tip is to normalise values, and show how the values vary between each other. Relative values are often easier to understand than absolute ones - remember too that most values have units, and that units matter. I’ve quizzed many PGRs on whether they are talking about Mbps or MBps - there’s a difference of eight in there! Draw some pictures. There is no place for trivial graphics and clip art in a PhD thesis, but there is a place for the abstraction of complex ideas, especially in the introduction. There no real need to just copy the graphics from others, as they should come from the ideas inspired by the writer. I’ve read quite a few thesis, where the text just goes on and on. Break the text up every now and then, and give the reader something to ponder over. Break up and but keep a narrative. There’s a careful balance here. If you keep your sections short, it becomes to “bitty”, and if you make them too long, they become long and unwieldy. I personally read whole sections in a single sitting, and try and take in the ideas, and I won’t move on until I understand it. A long section, especially where there are no sub-sections, often introduces too many concepts which can make it difficult to read. I normally recommend a maximum of a page and a half of text before there should be a break (such as a sub-section break). Long paragraphs are not a good thing as it becomes difficult to take in all the concepts introduced. Try, if possible, not to make them too short, but not too long. A paragraph that goes on for half a page is probably too long, and one that has only two sentences is probably too short. Along try and avoid too many sub-sub sections, as it becomes difficult for the reader to put it all into context. Avoid using the words of others too much. A thesis is written by the writer, and it is their words. A long series of indented text items of quoted material becomes fairly generic, where you get little of the sense of the thoughts of the writer. If you must reference others, pull it out, and indent. Be precise. A PhD thesis should be a scientific document which abides to certain standards for the articulation of ideas. It is always sloppy to see a candidate writing 9*6^3, where the “*” is a sloppy way of writing a multiply symbol (x) and ^ should be “to the power off”. If it’s an equation, it should be pulled out of the text, and a proper equation editor should be used, with a proper numbering system for the equation. Every diagram and table should be referenced in the text. I have read many thesis’ (typically drafts) where the writer just assumes that the reader knows how a diagram or table should integrate with the narrative. Every figure and table should thus be referenced in the text, so that the reader knows when to look at it. If possible don’t break up your narrative with a diagram, and move it a little later on, as long as it is after then text which is referring to it. Don’t ever put a diagram in the text before it is actually referred to, as the reader is left confused as to why the diagram is there. Be critical of yourself and others. One of the key things within a PhD is the ability to critically appraise the work of others, both for the strengths and weaknesses of their work, and also of the candidate’s work. I often circle the first signs of critical thought in a thesis. If it happens on Page 50, there’s a problem in not being able to critically appraise work. Along with this some candidates can think that everything is perfect with their work, and that it addresses every single problem in their field. Try to always define both the strengths and weaknesses your own work, and identify how these could be improved. The scope of the impact should never be overestimated, but also not underestimated. If you’ve developed something that completely changed something, be up-front and tell the reader. Most of the times, be honest to say that you are just enhancing something a little bit. A thesis is not a diary! I have read so many thesis’ which are basically just a chronological flow of their research. You can often spot this as the literature review runs out of references which are up-to-date. I have read several thesis’ where the latest reference in the literature review is two years ago, and it points to the fact that it has not been updated since it was initially written. A literature review should be written for the thesis, and many parts of the original literature can be dumped, and replaced with newer references which fit in with the contribution. Focus the literature review on the contribution. One literature review of PhD thesis I read was almost 200 pages long, and my head was spinning at the end of it. It covered so many points, and few of them actually went anywhere in the following chapters. Try and focus the literature review on covering the 4 or 5 key concepts involved in the thesis, and not in the research project. A good supervisor can often spot redundant sections, and advise for them to be cut. If the thesis is still the same by taking something out, there’s no need for it to be there, as every paragraph and every word should count, and be carefully crafted as part of the whole story. Make sure the aim is “of the thesis, and not “of the initial research project”. Many thesis’ start with “The aim of this research project is …” which often is a sign that the original project aim has not changed in the writing of the thesis. Overall the aim is the aim of the thesis, as the research project has finished. Every should be written from a point-of-view that the work has finished, and this is the write-up. Get the flow right. A strong flow of literature, method, build and evaluation helps the flow of the thesis, and where you often see references to literature tailing off as the thesis develops. I’ve seen some thesis’ where there are whole chapters that lack any form of reference to other work. This is poor practice as a PhD thesis should show how every aspect of the work fits in with the work of others. I like to see a reference to other work in the introduction of a chapter, as it shows some key influences for the work. I personally don’t like an introduction that says “Section 1 says this, and Section 2 says that, and Section 3 says something else”, as I can see from the table of contents what the contents are. If possible the reader should tell the reader what is likely to be revealed and what the significance is. A reinforcement of the main drive of the work also helps to bring the focus onto the main contribution of the work. If you don’t know it … don’t say it! This one seems so obvious, but you won’t believe the number of times that you ask in a Viva about the detail of a paper, and the method used, and for the answer to be that they don’t actually know what it does. You always increase your exposure to probing if you include things you don’t quite understand, so dump them (if they are not a core topic). Explain it simply. There’s nothing nicer for an examiner when the candidate takes a complex idea and gives their own viewpoint on it, in a simple way, using new material. It shows that they can articulate complex ideas in a simple way. The standard test for any thesis is that a 14-year old child should, at least, be able to read it, and understand some of the key concepts in it. Show that you love the subject and that it is relevant. Three years is a long time, but the sustainment of interest is a key part of the work, so try and show that this is an important topic and that your thesis is exactly what is required, and in the impact that it could have. Again the Introduction chapter is a great place to grab the reader, and show how important the work is. If possible try and find something that has just happened in the news in the introduction that shows how important your work is. The Introduction chapter, at least, should be readable by all, and where, at the end of it, most readers would want to read on, as it sounds so interesting. Make your thesis a sandwich. With a good thesis, we open with the Introduction and close on the Conclusions. The bit in-between justifies what you have opened with and the conclusions should show what you have uncovered to justify your argument. The same goes for each chapter, where the introduction (half a page, typically) shows what you’re going to tell them, and the conclusion confirms it. Do not make conclusion into a summary, as the reader has no time to read summaries, and just wants you to conclude the most important things that go forward (and so they can dump all the other things that you covered). If possible say why you are not taking some things forward in the conclusions (and justify using the work of others, if possible). Don’t just pick without reviewing and justifying. There is no justification in a thesis for picking something just because it is easy to get. If possible all the things that are selected have at least been reviewed, and a sensible solution is selected (and justified). Try always to select a few competing methods and tools and put them against each other. Validate before Evaluate. You won’t believe the number of Vivas that I’ve done where I’ve asked if they validated their system or software before they went onto evaluating it. So “How do you it takes 5 milliseconds to get from here to there?, the wrong answer is “… because the package said it was 5 milliseconds”. Good experimenters will do “fag packet” calculations, to estimate things and know the limits of what they expect. I always like to see validation tests within the test data, so that the researcher knows that their system is working correctly. There’s nothing work in finding there is a bug in your results, after you have published them … so always have a sanity check. Get that scientific method. There are so many occasions in a thesis where you have no idea what a graph is telling you, as the axis’ are not numbered properly, or where they are poorly scaled. If the variation is between 990 and 1000, don’t draw a graph which goes from 0 to 1000. Work out what the graph is trying to say, and pick the graph type (eg pie chart to show significant of one method against another) to show this. Must be based on a method and be repeatable. There must be a method in the processes used, and designed in a scientific way. Along with this the thesis should outline the procedure in a repeatable way, so that someone else can perform the same evaluation and get the same results. So candidates should always say to themselves… “Is there enough information for someone to build the artefact?”, “Is there enough information to repeat the experiment?”, and “Do I have the data that the examiner can look at, in order to verify the evaluation?” Evaluate your method against others. The standard method to show a contribution is to take your method and evaluate it against other competing methods. The best approach is to use the best competing method and show an improvement. This can sometimes be difficult, so, at least, there is an evaluation against other methods. Showing an improvement is obviously a good thing, but there is often nothing wrong with an evaluation which shows a negative impact, especially if it is backed-up with a strong critical appraisal. Be fair and honest with your experiments. Often an experimental procedure is selected to benefit your own method. If possible be fair on all the methods and do not bias your approach to your one. It does no harm to show weaknesses and downsides to your own contribution, as it gives you a chance to critically appraise and show how future work could improve things. Your experimental procedure and the associated data collection should be repeatable and verifiable, so don’t delete that data you have gathered. If possible, know your examination team. While the thesis should stand-alone you should also know your examination team before the Viva, so avoid patronising them with background theory which they know inside-out, or provide some background which might help the examiners to understand the area. Often an examiner, as part of the Viva, will give advice on moving things between the core material and appendices, in order to address the target audience for the thesis. Show that you are now an expert in your area. People expect those with a PhD to be an expert in the area of study, so make sure you know your core principles in the subject area. If you are doing a cryptography PhD read around the subject, and know the core principles of the most important methods. For me, anyone doing a PhD in electrical engineering, for example, should know Ohms Law, and the same should go for other subjects. Use appendices. Many PhD thesis’ are full of material that is irrelevant to many of the key arguments, and writers are often too sensitive about removing material. If you can, put unrelated material in an appendix, and just refer to it. As a measure, if any material doesn’t help your core arguments, then remove it, as you are wasting the reader’s time. Quality is better than quantity. Some of the best thesis’ I read have been relatively short and sharp, but where the quality is high. A good eye for moving material in appendices is important and helps the examiner. For some reason, candidates like to produce a thick thesis, and they think that the more pages there, the better the material. This is often the opposite, and a thesis written with self-contained papers for chapters - which link together - are often the best in their presentation. Define published work. A key part of PhD study is the dissemination of the work, especially with peer reviewed. The examiner often needs to know what has been published. Watch those unreliable references. In a PhD thesis, the references should be credible and verifiable references, and references to industry-focused white papers or general Web pages cannot be trusted providing credible viewpoints. Look for small-scale to large-scale experiments. A good researcher will often start small scale and prove the principle, and then look for a large-scale experiment. The sign of small experiments, along with a large-scale experiment which properly evaluates the methods presented, is a good sign of a strong research ethos. Few abstracts are actually any good in first draft. For some reason most PGRs struggle to write an abstract, and often it is written more as an introduction rather than a distilled version of the thesis. Remember that the abstract is the first thing that the reader reads, so if it is not focused on presenting the whole of the thesis, you have missed an opportunity to get the reader on your side. If possible an abstract should be a page in length, and outline the problem, the contribution, the most significant methods, the thing that has been designed/modelled, what has been evaluated, and what the most significant result is. Conclusions should conclude the whole thesis. Often the thesis just verifies aims and shows the significance of the results, but it should also recap the key parts of the literature and the other chapters. Mind those commas. Commas seem to be a dying breed, but are there to help speak directly to the reader. Try and read out loud, and if there’s a slight pause, add a comma. End on a high! Don’t spoil your thesis, by adding another chapter after the main contribution. Leave the reader on a high, and get them into the Conclusions, and leave the stage. I’ve read a few thesis’ where the last chapter is a real let-down, and contributes very little to the overall focus of the work. If you want, put your lovely new models in an appendix, and refer them in the main chapters, but try and finish the main chapters with the answer to the question posed at the start. The last dot of the last main chapter cements the argument, so don’t run on into something else that you just happens to be which you are currently looking at, as just feel your thesis isn’t thick enough yet! Sign post your work. Remember the thicker the thesis, the longer it takes to read, and if it doesn’t get to the point, the more annoyed the reader becomes in actually showing how you have addressed the problem and your main contribution. The more focused the thesis, the shorter time it will take to understand it, and the happier the examiner will be when they are reading it. Add pointers to “wake up” the reader and tell them that they really should read this bit … as I’m telling you something important. Guide but stay on the academic track. Guide them through difficult areas, and allow them to learn from your love of the topic and your new insights, but stick to well-defined academic principles for writing a thesis … such as not adding your own opinions in literature review parts. Leave your thoughts for the conclusion section with a chapter. Try not to hint that you’ve solved every problem in the area, and rely on showing your contribution on the back of others, including within the main conclusions. Be humble. Show that you are humble in your writing and respect (and know) the most important people in your area (including your external examiner), and that you want to be an active part of your community, and help them. The PhD is not an end-stop, but shows how you will work in the future … either in academia or industry. So just because you are off to a job in industry, doesn’t mean that your research career ends at the graduation … you have standards and methods to set for others to follow.

Submission ¶

You must submit your thesis within three years and six months (allowing for any interruptions or extensions that you may have been granted). When you are ready to submit your thesis you need to complete a Notice of Submission Form not less than six weeks before submission.This form is available in eProg in the Examination Summary section. You will also need to read Regulations for the Presentation of Theses and Dissertations. Giving notice of submission triggers the process of appointing the examiners, who are then expecting the thesis to arrive on time.

If a thesis is not submitted before the end of the programme or submission pending period, you will not be able submit your thesis without exceptional circumstances.

You must submit an electronic copy of your thesis no less than 3 days before your final submission deadline. You must submit two hard copies to the Faculty Graduate Office by the deadline. The electronic and hard copies must be identical.

If you wish to submit a thesis more than 3 months before the end of your programme (or 6 months if part time) you will require a permission of your supervisor and the University. If you are granted permission to submit early then you will still be required to pay full fees for the degree period for which you originally registered.

Using eProg for everything. You first need to submit a notification that you are ready to submit within 6 weeks - a submission ‘window’ will then be opened. You can then submit at anytime within that six weeks. If you do not submit you have failed.

Open access: submit and share your research

‌Once you have submitted your thesis you should consider how you will share your research more widely. Making your outputs OA can provide important  benefits  to you as a researcher, to the research community, and the wider world.

University of Manchester Postgraduate research students are required to share journal articles and peer-reviewed conference proceedings under the institutional  Publications Policy . Making these outputs Open Access (OA) is also required by Research England in order for papers to be eligible for submission to the REF, and many research funders require OA for these outputs too. Use the  Library deposit form in the Open Access Gateway  to submit your papers for deposit to ensure they are made OA as required.

If you wish to ask a general question about Open Access, you can contact the Library’s OA team using the Open Access enquiry form or via email: uml . openaccess @ manchester . ac . uk

The Thesis Defence (Viva) ¶

You will need to defend your thesis in an oral examination which is often called a ‘viva’ (for viva voce). You will typically have two examiners comprising either (i) an internal examiner (a member of academic staff from Manchester who has expertise in your research area) and an external examiner (a member of academic staff from another university or another suitably-qualified and research-active expert), or (ii) two external examiners and an internal independent chair. The internal examiner or independent chair will arrange the date and time of your oral examination. There may also be an independent chair when one of the examiners lacks experience in examining doctorates and in other situations.

In the oral examination you will be examined orally on the content of your thesis and its wider context. After the examination the examiners will make a recommendation to the Faculty PGR Degrees Panel on the outcome of the exam. The examiners may communicate what their recommendation is to you, but it should be clear that this is unofficial and the final decision is made by Faculty.

The outcomes are:

recommend the award and no corrections are necessary.

recommend the award subject to minor corrections being completed.

refer: the thesis is satisfactory in substance but defective in presentation; allow resubmission without the need for a further oral examination.

refer: the thesis is satisfactory in substance but defective in presentation; allow resubmission and require a further oral examination.

refer: the thesis requires further research to be done; allow resubmission and require a further oral examination.

award MPhil on the basis of the thesis presented.

award MPhil on the basis of the thesis presented, subject to minor corrections being completed.

reject, but invite the candidate to revise and resubmit the thesis for the degree of MPhil within six months. A candidate will be permitted to resubmit on only one occasion. A fresh examination of the thesis will be required and may include a further oral examination.

no award be made to the candidate and no resubmission be permitted.

The most common outcome is A(ii). Normally minor corrections required under A(ii) must be completed within 4 weeks of the result being communicated to you by the Faculty PGR Degrees Panel. Likewise with the outcome C(ii) the minor corrections required for award of MPhil must be completed within 4 weeks.

PGRs with outcomes B(i)–B(ii) and C(iii) normally have up to six months to resubmit their thesis (in the latter case for MPhil). PGRs with outcomes B(iii) have one year to resubmit their thesis. A resubmission fee is charged.

Viva Format ¶

Following the relaxation of national COVID restrictions on 19th July 2021 vivas can now be held either entirely in-person, remotely via video link, or a hybrid approach can be adopted whereby one or more members of the examination appear via a video link.

As the PGR this is pretty much your choice - although we suggest you discuss it with your supervisory team and make sure the examiners are happy with the choice before the agree to whichever ‘flavour’ or viva is chosen.

Viva Advice ¶

Further advice from Prof Bill Buchanan OBE, PhD, FBCS - Professor at Edinburgh Napier University:

Be ready to defend, up to a point. You are unlikely to ever win with a debate with the External Examiner, as they typically have the experience to know when they are right. The Examiner does want to see you putting up arguments against theirs, and not bend. A strategy is often to debate the case, and try different routes of explanation, but then to take on their advice for any changes that would be required. Draw it out and keep it simple. Drawing diagrams and abstracting is a great way to explain your ideas, so wherever possible try to draw an abstraction to show a key point. Try not to over complex things, as they examiner is often looking for you to article complex ideas in a simple and understandable way. The simplest things are often the most difficult to explain. Many candidates go into a Viva thinking they will get probed on the complex areas of their work, but end up having to justify an extremely simple concept, that they have taken for granted. An examiner can often spot a weakness in some fundamental areas and probe around that, in order to see how the candidate thinks through a problem. So candidates should also try and be well versed on the fundamentals areas, especially when it involves maths. Know your examiners. Every examiner is different, and they have their own style. Some go from page to page, others read generally around significant parts of the work. They will generally have expertise in certain areas, so try and understand their motivations in their research, and some of their specialities, as they are likely to draw on these for questions. Don’t leave it too long for the Viva. The best time for a Viva is straight after you’ve written your thesis, so try and don’t leave it too long for the Viva, as you will forget a few things. Stay calm and enjoy. It is your opportunity to lock horns with an expert in their field, so enjoy it, as you’ll probably never have the chance to do something like this in your career. Be humble. A PhD is a long road, and you learn along that road. The end result should setup you up for the even longer road ahead, but you now have all the tools to be ready for a career in research. None of us truly knows the formula for a successful PhD, but the methods applied by examiners and supervisors have stood the test of time, and do actually result in something that can contribute to the body of science. Remember that you are standing on the shoulders of giants. A key thing is knowing whose shoulders you are standing on, and help the others who could stand on your shoulders. Enjoy your time! And finally, for a bit of advice, have a look at Ralph Merkle’s time. He invented key exchange while an undergraduate, but his professor rejected his ideas because he didn’t articulate them properly, and Ralph then tried to publish a paper on it, but it was rejected because he had no literature in the paper. So, try and write well … and perfect the art of speaking directly to the reader, and also follow the rules of research that have been laid down over the centuries, and you’re halfway there.

Corrections ¶

Once you have had your viva you will typically get corrections. Once you have completed the corrections, they send a PDF copy of the corrected thesis directly to the internal examiner for approval.

Once the examiner is happy the corrections have been completed, they need to fill out the Corrections Sign Off Form on eProg. Once that’s been completed, we can open a Final Submission Window for you to submit in eThesis. Once received and acknowledged, We can then produce an award letter and complete yout studies on Campus Solutions.

Defending your doctoral thesis: the PhD viva

Format for defending a doctoral thesis.

Every institution will have specific regulations for the thesis defence. In some countries or institutions, the convention is for thesis defences to be public events where you will give a lecture explaining your research, followed by a discussion with a panel of examiners (opponents). Both your examiners and the audience are able to ask questions.

In other countries, including the UK, the oral examination is usually conducted behind closed doors by at least two examiners, usually with at least one being from another institution (external examiner) and an expert in your topic of research. In the UK the supervisor does not participate in the viva, but may be allowed to observe. Sometimes someone from your own institution is appointed as an independent chair. Although it is now becoming more common for the candidate to have an opportunity to give a public lecture in UK institutions, this does not form part of the examination and may or may not be attended by the examiners.

Viva preparation

Take the preparation for your viva seriously and devote a substantial amount of time to it. The viva preparation checklist may be useful to help you prepare.

Your institution may offer courses on viva preparation and there may be opportunities to organise a practice viva. Take advantage of these opportunities: they can be extremely valuable experiences.

Things you may wish to take with you

• your thesis – mildly annotated if you wish
• a list of questions that you might be asked and your planned responses
• any questions that you want to ask your examiners
• additional notes which you have made during your revision
• list of minor corrections that you have come across during your revision.

During the viva

Your study will have strengths and weaknesses: it is essential that you are prepared to discuss both. You could think of any weaknesses as an opportunity to demonstrate your skill at critical appraisal. Examiners will seek to find and discuss weaknesses in all theses. Do not interpret criticism as indication of a possible negative outcome.

Examiners have different personalities, styles and levels of experience. Sometimes a candidate may feel that a challenge is made in a confrontational way. Experienced, effective examiners will not be inappropriately confrontational, but some will. Do not take offence. A relaxed, thoughtful, and non-confrontational response from you will help re-balance the discussion. Having an independent chair can help maintain a constructive environment.

Useful tips for during your viva:

• Ask for clarification of ambiguous questions or ask for the question to be repeated if necessary
• Take time to think before answering
• Be prepared to ask questions and enter into a dialogue with your examiners
• Be prepared to discuss your research in context of other work done in your field
• Be ready to admit if you don't know the answer to a question
• Be prepared to express opinions of your own

You are not expected to have perfect recall of your thesis and everything that you have read and done. If you get flustered, or need to refer to notes your examiners will understand. They have been in your situation themselves!

After your viva

There are several possible outcomes   of a thesis defence. Most commonly, your examiners will recommend to your institution that you are awarded your degree subject to minor corrections, although in some instances they might ask for more substantial work.
