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.

What is a PhD Defence?

At its core, a PhD defence is a rigorous and comprehensive examination that marks the culmination of a doctoral candidate’s research journey. It is an essential component of the doctoral process in which the candidate is required to defend their dissertation before a committee of experts in the field. The defence serves multiple purposes, acting as both a showcase of the candidate’s work and an evaluative measure of their understanding, critical thinking, and contributions to the academic domain.

The primary goals of a PhD defence include:

Presentation of Research: The candidate presents the key findings, methodology, and significance of their research.
Demonstration of Mastery: The defence assesses the candidate’s depth of understanding, mastery of the subject matter, and ability to engage in scholarly discourse.
Critical Examination: Committee members rigorously question the candidate, challenging assumptions, testing methodologies, and probing the boundaries of the research.
Validation of Originality: The defence validates the originality and contribution of the candidate’s work to the existing body of knowledge.

The PhD defence often takes the form of an oral examination, commonly referred to as the viva voce. This oral component adds a dynamic and interactive dimension to the evaluation process. Key elements of the oral examination include:

Presentation: The candidate typically begins with a formal presentation, summarizing the dissertation’s main components, methodology, and findings. This presentation is an opportunity to showcase the significance and novelty of the research.
Questioning and Discussion: Following the presentation, the candidate engages in a thorough questioning session with the examination committee. Committee members explore various aspects of the research, challenging the candidates to articulate their rationale, defend their conclusions, and respond to critiques.
Defence of Methodology: The candidate is often required to defend the chosen research methodology, demonstrating its appropriateness, rigour, and contribution to the field.
Evaluation of Contributions: Committee members assess the originality and impact of the candidate’s contributions to the academic discipline, seeking to understand how the research advances existing knowledge.

The oral examination is not a mere formality; it is a dynamic exchange that tests the candidate’s intellectual acumen, research skills, and capacity to contribute meaningfully to the scholarly community.

In essence, the PhD defence is a comprehensive and interactive evaluation that encapsulates the essence of a candidate’s research journey, demanding a synthesis of knowledge, clarity of expression, and the ability to navigate the complexities of academic inquiry. As we delve into the specifics of the defence process, we will unravel the layers of preparation and skill required to navigate this transformative academic milestone.

How Long is a PhD Defence?

The duration of a PhD defence can vary widely, but it typically ranges from two to three hours. This time frame encompasses the candidate’s presentation of their research, questioning and discussions with the examination committee, and any additional deliberations or decisions by the committee. However, it’s essential to note that this is a general guideline, and actual defence durations may vary based on numerous factors.

Sciences and Engineering: Defenses in these fields might lean towards the shorter end of the spectrum, often around two hours. The focus is often on the methodology, results, and technical aspects.
Humanities and Social Sciences: Given the theoretical and interpretive nature of research in these fields, defences might extend closer to three hours or more. Discussions may delve into philosophical underpinnings and nuanced interpretations.
Simple vs. Complex Studies: The complexity of the research itself plays a role. Elaborate experiments, extensive datasets, or intricate theoretical frameworks may necessitate a more extended defence.
Number of Committee Members: A larger committee or one with diverse expertise may lead to more extensive discussions and varied perspectives, potentially elongating the defence.
Committee Engagement: The level of engagement and probing by committee members can influence the overall duration. In-depth discussions or debates may extend the defence time.
Cultural Norms: In some countries, the oral defence might be more ceremonial, with less emphasis on intense questioning. In others, a rigorous and extended defence might be the norm.
Evaluation Practices: Different academic systems have varying evaluation criteria, which can impact the duration of the defence.
Institutional Guidelines: Some institutions may have specific guidelines on defence durations, influencing the overall time allotted for the process.

Candidates should be well-prepared for a defence of any duration. Adequate preparation not only involves a concise presentation of the research but also anticipates potential questions and engages in thoughtful discussions. Additionally, candidates should be flexible and responsive to the dynamics of the defense, adapting to the pace set by the committee.

Success Factors in a PhD Defence

Successful defence begins with a deep and comprehensive understanding of the research. Candidates should be well-versed in every aspect of their study, from the theoretical framework to the methodology and findings.
Thorough preparation involves anticipating potential questions from the examination committee. Candidates should consider the strengths and limitations of their research and be ready to address queries related to methodology, data analysis, and theoretical underpinnings.
Conducting mock defences with peers or mentors can be invaluable. It helps refine the presentation, exposes potential areas of weakness, and provides an opportunity to practice responding to challenging questions.
Actively listen to questions without interruption. Understanding the nuances of each question is crucial for providing precise and relevant responses.
Responses should be clear, concise, and directly address the question. Avoid unnecessary jargon, and strive to convey complex concepts in a manner that is accessible to the entire committee.
It’s acceptable not to have all the answers. If faced with a question that stumps you, acknowledge it honestly. Expressing a willingness to explore the topic further demonstrates intellectual humility.
Use questions as opportunities to reinforce key messages from the research. Skillfully link responses back to the core contributions of the study, emphasizing its significance.
Rehearse the presentation multiple times to build familiarity with the material. This enhances confidence, reduces nervousness, and ensures a smooth and engaging delivery.
Maintain confident and open body language. Stand tall, make eye contact, and use gestures judiciously. A composed demeanour contributes to a positive impression.
Acknowledge and manage nervousness. It’s natural to feel some anxiety, but channelling that energy into enthusiasm for presenting your research can turn nervousness into a positive force.
Engage with the committee through a dynamic and interactive presentation. Invite questions during the presentation to create a more conversational atmosphere.
Utilize visual aids effectively. Slides or other visual elements should complement the spoken presentation, reinforcing key points without overwhelming the audience.
View the defence not only as an evaluation but also as an opportunity for continuous improvement. Feedback received during the defence can inform future research endeavours and scholarly pursuits.

In essence, success in a PhD defence hinges on meticulous preparation, adept handling of questions, and projecting confidence and composure during the presentation. A well-prepared and resilient candidate is better positioned to navigate the challenges of the defence, transforming it from a moment of evaluation into an affirmation of scholarly achievement.

Failure in PhD Defence

While the prospect of failing a PhD defence is relatively rare, it’s essential for candidates to acknowledge that the possibility exists. Understanding this reality can motivate diligent preparation and a proactive approach to mitigate potential risks.
Failure, if it occurs, should be seen as a learning opportunity rather than a definitive endpoint. It may highlight areas for improvement and offer insights into refining the research and presentation.
Lack of thorough preparation, including a weak grasp of the research content, inadequate rehearsal, and failure to anticipate potential questions, can contribute to failure.
Inability to effectively defend the chosen research methodology, including justifying its appropriateness and demonstrating its rigour, can be a critical factor.
Failing to clearly articulate the original contributions of the research and its significance to the field may lead to a negative assessment.
Responding defensively to questions, exhibiting a lack of openness to critique, or being unwilling to acknowledge limitations can impact the overall impression.
Inability to address committee concerns or incorporate constructive feedback received during the defense may contribute to a negative outcome.
Comprehensive preparation is the cornerstone of success. Candidates should dedicate ample time to understanding every facet of their research, conducting mock defences, and seeking feedback.
Identify potential weaknesses in the research and address them proactively. Being aware of limitations and articulating plans for addressing them in future work demonstrates foresight.
Engage with mentors, peers, or advisors before the defence. Solicit constructive feedback on both the content and delivery of the presentation to refine and strengthen the defence.
Develop strategies to manage stress and nervousness. Techniques such as mindfulness, deep breathing, or visualization can be effective in maintaining composure during the defence.
Conduct a pre-defense review of all materials, ensuring that the presentation aligns with the dissertation and that visual aids are clear and supportive.
Approach the defence with an open and reflective attitude. Embrace critique as an opportunity for improvement rather than as a personal affront.
Clarify expectations with the examination committee beforehand. Understanding the committee’s focus areas and preferences can guide preparation efforts.
In the event of failure, candidates should approach the situation with resilience. Seek feedback from the committee, understand the reasons for the outcome, and use the experience as a springboard for improvement.

In summary, while the prospect of failing a PhD defence is uncommon, acknowledging its possibility and taking proactive steps to mitigate risks are crucial elements of a well-rounded defence strategy. By addressing common failure factors through thorough preparation, openness to critique, and a resilient attitude, candidates can increase their chances of a successful defence outcome.

PhD Defense or Defence?

The choice between “defense” and “defence” is primarily a matter of British English versus American English spelling conventions. “Defense” is the preferred spelling in American English, while “defence” is the British English spelling.
In the global academic community, both spellings are generally understood and accepted. However, the choice of spelling may be influenced by the academic institution’s language conventions or the preferences of individual scholars.
Academic institutions may have specific guidelines regarding language conventions, and candidates are often expected to adhere to the institution’s preferred spelling.
Candidates may also consider the preferences of their advisors or committee members. If there is a consistent spelling convention used within the academic department, it is advisable to align with those preferences.
Consideration should be given to the spelling conventions of scholarly journals in the candidate’s field. If intending to publish research stemming from the dissertation, aligning with the conventions of target journals is prudent.
If the defense presentation or dissertation will be shared with an international audience, using a more universally recognized spelling (such as “defense”) may be preferred to ensure clarity and accessibility.
Regardless of the chosen spelling, it’s crucial to maintain consistency throughout the document. Mixing spellings can distract from the content and may be perceived as an oversight.
In oral presentations and written correspondence related to the defence, including emails, it’s advisable to maintain consistency with the chosen spelling to present a professional and polished image.
Recognizing that language conventions can vary, candidates should approach the choice of spelling with flexibility. Being adaptable to the preferences of the academic context and demonstrating an awareness of regional variations reflects a nuanced understanding of language usage.
With the increasing globalization of academia, an awareness of language variations becomes essential. Scholars often collaborate across borders, and an inclusive approach to language conventions contributes to effective communication and collaboration.

In summary, the choice between “PhD defense” and “PhD defence” boils down to regional language conventions and institutional preferences. Maintaining consistency, being mindful of the target audience, and adapting to the expectations of the academic community contribute to a polished and professional presentation, whether in written documents or oral defences.

Is PhD Defense a Formality?

While the PhD defence is a structured and ritualistic event, it is far from being a mere formality. It is a critical and substantive part of the doctoral journey, designed to rigorously evaluate the candidate’s research contributions, understanding of the field, and ability to engage in scholarly discourse.
The defence is not a checkbox to be marked but rather a dynamic process where the candidate’s research is evaluated for its scholarly merit. The committee scrutinizes the originality, significance, and methodology of the research, aiming to ensure it meets the standards of advanced academic work.
Far from a passive or purely ceremonial event, the defence involves active engagement between the candidate and the examination committee. Questions, discussions, and debates are integral components that enrich the scholarly exchange during the defence.
The defence serves as a platform for the candidate to demonstrate the originality of their research. Committee members assess the novelty of the contributions, ensuring that the work adds value to the existing body of knowledge.
Beyond the content, the defence evaluates the methodological rigour of the research. Committee members assess whether the chosen methodology is appropriate, well-executed, and contributes to the validity of the findings.
Successful completion of the defence affirms the candidate’s ability to contribute meaningfully to the academic discourse in their field. It is an endorsement of the candidate’s position as a knowledgeable and respected scholar.
The defence process acts as a quality assurance mechanism in academia. It ensures that individuals awarded a doctoral degree have undergone a thorough and rigorous evaluation, upholding the standards of excellence in research and scholarly inquiry.
Institutions have specific criteria and standards for awarding a PhD. The defence process aligns with these institutional and academic standards, providing a consistent and transparent mechanism for evaluating candidates.
Successful completion of the defence is a pivotal moment that marks the transition from a doctoral candidate to a recognized scholar. It opens doors to further contributions, collaborations, and opportunities within the academic community.
Research presented during the defence often forms the basis for future publications. The validation received in the defence enhances the credibility of the research, facilitating its dissemination and impact within the academic community.
Beyond the academic realm, a successfully defended PhD is a key credential for professional advancement. It enhances one’s standing in the broader professional landscape, opening doors to research positions, teaching opportunities, and leadership roles.

In essence, the PhD defence is a rigorous and meaningful process that goes beyond formalities, playing a crucial role in affirming the academic merit of a candidate’s research and marking the culmination of their journey toward scholarly recognition.

Dressing for Success: PhD Defense Outfit

For Men: A well-fitted suit in neutral colours (black, navy, grey), a collared dress shirt, a tie, and formal dress shoes.
For Women: A tailored suit, a blouse or button-down shirt, and closed-toe dress shoes.
Dress codes can vary based on cultural expectations. It’s advisable to be aware of any cultural nuances within the academic institution and to adapt attire accordingly.
With the rise of virtual defenses, considerations for attire remain relevant. Even in online settings, dressing professionally contributes to a polished and serious demeanor. Virtual attire can mirror what one would wear in-person, focusing on the upper body visible on camera.
The attire chosen for a PhD defense contributes to the first impression that a candidate makes on the examination committee. A professional and polished appearance sets a positive tone for the defense.
Dressing appropriately reflects respect for the gravity of the occasion. It acknowledges the significance of the defense as a formal evaluation of one’s scholarly contributions.
Wearing professional attire can contribute to a boost in confidence. When individuals feel well-dressed and put-together, it can positively impact their mindset and overall presentation.
The PhD defense is a serious academic event, and dressing professionally fosters an atmosphere of seriousness and commitment to the scholarly process. It aligns with the respect one accords to academic traditions.
Institutional norms may influence dress expectations. Some academic institutions may have specific guidelines regarding attire for formal events, and candidates should be aware of and adhere to these norms.
While adhering to the formality expected in academic settings, individuals can also express their personal style within the bounds of professionalism. It’s about finding a balance between institutional expectations and personal comfort.
Select and prepare the outfit well in advance to avoid last-minute stress. Ensure that the attire is clean, well-ironed, and in good condition.
Accessories such as ties, scarves, or jewelry should complement the outfit. However, it’s advisable to keep accessories subtle to maintain a professional appearance.
While dressing professionally, prioritize comfort. PhD defenses can be mentally demanding, and comfortable attire can contribute to a more confident and composed demeanor.
Pay attention to grooming, including personal hygiene and haircare. A well-groomed appearance contributes to an overall polished look.
Start preparation well in advance of the defense date. Know your research inside out, anticipate potential questions, and be ready to discuss the nuances of your methodology, findings, and contributions.

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.

Thesis defense.

This is a comprehensive guide, written specifically for SMD graduate students. The guide covers everything from before the defense, to the defense itself, to after the defense, providing information about the process, outlining requirements and offering useful tips. Please refer to the Timeline for PhD Defense

Before Defense

Get permission to start writing.

After completing all course, seminar, TA, publication and research requirements for your program of study, there are many things that must be done before a thesis defense can occur. Most importantly, you must meet with your advisory committee at least 6 months before you intend to defend your thesis. Your advisor and committee need to agree to your intentions to conclude experiments and data collection and begin writing. Once you get the go-ahead to start writing your thesis, you will need to decide on a date by which the defense should occur. You will also need to inform your program director and graduate program coordinator that you have started the process to defend.

Chair for Your Defense

A Chair is appointed for each PhD oral defense exam to monitor and promote fairness and rigor in the conduct of the defense.

At least 4 months prior to your defense, you, with support from your advisor and/or program director, must identify a faculty member to serve as Chair for your defense. The Chair must be a current full-time tenure-track University of Rochester faculty member at assistant professor rank or higher who is external to the program, and without a significant scholarly relationship with the candidate or other committee members. You must include the Chair in planning for specific dates and times for your defense.

Selecting a Defense Date

If all goes as planned and you have made sufficient progress in your writing, schedule the actual defense date at least three months in advance to ensure that your advisor, all committee members and your appointed Chair are able to be present at your defense and that rooms are available on the date and time selected.

The academic calendar includes important dates for defense for each semester of the academic year. When you begin thinking about defending, check the academic calendar for deadlines and blackout dates (periods of time when defenses are not permitted). This will make identifying possible dates for defense a lot easier for you, your committee members and your Chair.

When all members of your committee and your Chair agree to a specific date and time for defense, inform your graduate program coordinator of the scheduled defense date as soon as you possibly can but no later than 8 weeks prior to your defense date. They will advise you of any program-specific requirements for the defense as well as prepare your Program Statement on Completion of PhD Requirements . This form requires your program director’s signature. Check with your graduate program coordinator to determine if you or they will obtain the signature for your form. Once approved and signed, this form along with others will be scanned and submitted via an online thesis registration system along with a pdf of your thesis and an Exit Interview Form and your CV/Resume.

International Students and Work Visas

It is strongly recommend that international students meet with an International Services Office rep as soon as permission to start writing is granted. The ISO will provide information on visa options, documentation and timelines for applying for a visa for employment in the US.

Registration Categories for Defense

In your final semester (the semester in which you defend), you will register for a placeholder registration category rather than PhD Research. The categories are:

“Dissertation” non-credit bearing registration category that indicates the PhD student has completed all of the requirements for the degree except the dissertation and is in residence as a full-time student.

You must be in residence full-time and planning for a defense in the upcoming semester. If a defense does not occur, the Registrar will change your registration for the semester to reflect credit hours.
You are eligible for student health insurance, loan deferments, and University housing, but not eligible for financial aid in the form of student loans.

"Continuation of Enrollment” non-credit bearing registration category that indicates the PhD student has completed all of the requirements for the degree except the dissertation and is not in residence as a full-time student. When registered for Continuation of Enrollment, your time status is less than half time.

Appropriate for the student who has left the University prior to completion for a job or personal reasons but has a defense planned during the upcoming semester.
Requires permission of the advisor, the program director, and the Dean.
You are not eligible for student health insurance, loan deferments, University housing, or financial aid in the form of student loans.

Thesis Writing and Guidelines

The preparation of doctoral theses–a manual for graduate students.

The University of Rochester offers this manual to graduate students and it is meant to help you to bring your thesis up to the required standard of organization, appearance, and format for the University of Rochester. Before preparing the defense copy of your thesis, check the contents of the manual systematically. In so doing, you may avoid mistakes that can be time-consuming and costly to correct. The manual does not deal with the art of scholarship. There are numerous guidebooks and style manuals available for dissertation writers. However, before beginning the writing of your dissertation, you should consult with your department regarding preferred styles.

Including material produced by other authors in your dissertation or thesis can serve a legitimate research purpose, but you want to avoid copyright infringement in the process. Republishing someone else's work, even in abbreviated form, requires permission from the author or copyright owner. You must receive permission from the author(s) and include it with your submission before it can be published in your dissertation.

For detailed guidance on avoiding copyright infringement, please see ProQuest’s Copyright Guide.

SMD Guidelines for the Content of a PhD Thesis

The School of Medicine and Dentistry offers this manual to graduate students in the basic sciences , Epidemiology , Health Services Research and Policy , and Statistics programs. These guides focus on how a thesis should be structured for writing and for the content that comprises a well-written thesis. They are meant to be a supplement to the general guidelines of the University of Rochester for preparation of a thesis (The Preparation of Doctoral Theses: A Manual for Graduate Students).

Statistics students should consult their program director for thesis requirements specific to the discipline. In the event you need assistance in writing your thesis, a Life Sciences Writing Specialist is available to work with you.

Rooms for Your Defense

Two rooms must be reserved: the first for your oral presentation and the second for your closed exam. Most often, the oral presentation is held in an auditorium and the closed exam is held in a departmental conference room. Check with your graduate program coordinator to determine if you or they will schedule rooms for your thesis defense.

Registering Your Thesis for the Final Oral Exam

You, your graduate program coordinator, or both of you together, will create your record in the University of Rochester Graduate Studies PhD Completion website . This record will include your degree information, past degrees, important contact information, and attachments including the defense version of your thesis in pdf format, and other relevant documents. The version of your thesis submitted to your online record is considered the registration copy. “Registering” simply means that you have presented a thesis, which you intend to defend, to the Dean of your School and to the University Dean that governs all doctoral candidates.

When the PhD Completion record is finalized (submitted) by your graduate program coordinator, your advisor and committee members will receive emails with links to access your record and to approve your thesis to progress to defense. Well before the online record is submitted, you must provide copies of the thesis identical to the registration copy to all members of your committee, as well as to your appointed Chair. Please consult with them for their preferred format. Some will accept a pdf and others will request a hard copy. Each of these individuals must have possession of your thesis for a minimum of two weeks before they are asked to sign off on the readiness of the work for defense. There may be deadlines for registering your thesis specific to your graduate program. Consult with your graduate program coordinator to ascertain those deadlines and follow them carefully. Please plan the completion of your degree by following your program’s deadlines in tandem with the academic calendar.

After all committee members have given approval, your program director, and the Registrar, will approve the thesis for registration using the same online system. Then, requests for review and approval will go to the Senior Associate Dean for Graduate Education and Postdoctoral Affairs and then to the office of the University Dean of Graduate Studies. When all of these officials have approved your committee and thesis for defense, it is considered registered. You will be able to track these approvals in your online record and will receive a confirmation email when approvals are complete.

Comments indicating required corrections to your thesis may be made by your advisor, committee members and the Deans along the way of the approval process. This annotated copy of the thesis, along with the original version, will be stored in the PhD Completion website for you to reference at the conclusion of your defense. You are not permitted to distribute updated versions prior to the defense, but be sure to incorporate any corrections in the final copy after the defense before uploading it to ProQuest®.

After the defense, if the committee required major revisions to be approved by one or more of its members, it is your responsibility to provide the corrected final version for their approval. They will be asked to submit written confirmation of that approval to University Graduate Studies. Failure to do so could delay conferral of your degree.

After the defense, you will receive additional instructions by email for completion of all PhD degree requirements.

The Defense

It is important to walk into the defense knowing that your Committee really WANTS you to pass. Even if criticism is harsh, it is meant to be constructive. After all, the defense is not solely an opportunity for the Committee to compliment and congratulate you for the work you have done. It is also meant to challenge you and force you to consider tough questions.

Below you will find suggestions to help you get ready for the defense and information to give you a sense of what to expect:

Know the Rituals

What happens at a thesis defense? The best way to know what happens and the best way for you to prepare for your defense is to regularly attend the defenses of your colleagues—those internal and external to your field of expertise. You should be doing this throughout your graduate program, not just several weeks prior to your own defense.

Talk to people from your lab and in your department who already defended to find out what their defense was like. They know well what occurs in the closed exam and will likely want to share their experiences with you. You should also speak with your advisor to get a sense of his/her specific expectations of a defense. Don’t be afraid to ask!

Guidelines for Presentations

Use powerpoint.

PowerPoint is a professional approach to presenting the research that comprises the thesis. Your slides should encapsulate the study and focus on its most salient findings. In preparing, ask yourself these questions: “What do I want people to know about my thesis? What is the most important information that I can present and talk about?” Keep in mind the rules of chartsmanship and create a goal-oriented presentation that navigates attendees through a logical, point-by-point sequence of information that builds to the conclusion in a clear and focused direction.

Use text large enough to be readable (especially text from figures)
Ensure graphics and tables are clear
Don’t clutter your slides – if necessary have things come up on mouse clicks
Use spell check and also proof-read
Practice presentation with your lab and peers
Work on pronunciation, if required
Time presentation to ensure it is long enough but will also allow time for questions

Public Lecture

It is recommended that you do a trial run of your presentation a day or two before your defense in the auditorium or room that has been booked for your public lecture. This will allow you to familiarize yourself with the space and the equipment and to address any problems that arise during the trial run.

Plan your public lecture to allow a 50 minute talk with 10 minutes for questions. Present enough information so that the audience understands what you did, why you did it, what the implications are and what your suggestions are for future research.

The date/time/location of your defense and thesis topic are published on the school’s website to invite the larger community to attend. Departmental/program announcements are sent by your Graduate program coordinator to invite faculty and students. Friends and family are welcome to attend the public lecture. Faculty and students in the audience are given the opportunity to ask questions when committee members conclude their questions.

Friendly Advice: Just before your talk, chat with friends and mingle with the crowd. This may reduce your anxiety and nervousness.

Prior to the defense, plan to provide friends and family with a map and directions to visitor parking lots at the Medical Center or Saunders Building as well as the name, room number and directions to the auditorium or room booked for your defense. You may also want to ask another student or postdoc to assist your friends and family on the day of your defense to get to your public lecture and to gather somewhere while you are engaged in the closed exam.

Dress Professionally

Plan to dress professionally for the defense in the same way you would if presenting a paper at a conference or for a job interview. Suits, ties, dresses, and skirts are the norm. You will be standing for a long time on the day of your defense. You might want to keep this in mind when selecting the shoes you’ll wear for your defense.

Items to Bring to the Defense

Your presentation, a laser pointer, a copy of your thesis, a pen or pencil, a note pad and a bottle of water are essentials that you should bring to the public lecture. Other things you feel you need (e.g. Kleenex tissues, a lucky charm, etc.) are acceptable to bring with you as well.

The Closed Examination

You will be asked to leave the room while your Committee reviews your program of study, grades and decides whether the thesis is acceptable/not acceptable. The Committee decides whether members will ask sequential questions or whether each member will be allotted a specific time period for questioning.

The person to start the questioning is designated. You will be called back into the examining room and questioning will begin. After all questions have been addressed you will be asked to leave the room. Your Committee decides the outcome of the exam. You will be asked to return to the room to be informed of the outcome by the Chair of your exam committee.

Address Questions with Confidence

Listen to the entire question no matter how long it takes the faculty member or student to ask it. (Take notes if necessary.)
Pause and think about the question before answering.
Rephrase the question succinctly.
Answer the question to the best of your ability. If you do not know the answer, remain calm and say so in a professional way.
Remember no one will know the ins and outs of the thesis and your research materials as well as you. You are the foremost expert in the thesis topic and YOU really do know the science involved. Be positive!
Passed – successfully performed in the final oral examination and thesis was acceptable
Passed pending revisions to the thesis - successfully performed in the final oral examination and thesis will be acceptable with revisions which are approved by the advisor and sometimes by all members of the committee
Did not pass – often based upon performance in the final oral examination

After the Defense

You will receive annotated copies of your thesis from the members of your examination committee. The Chair will give you a packet of paperwork that includes:

Survey of the Earned Doctorate
Instructions for submission of the final thesis to ProQuest Dissertation Publishing
University of Rochester publishing agreement

The survey and UR publishing agreement are expected to be submitted to the University Dean by the date the final copy of the thesis is submitted to ProQuest. Students have 60 calendar days after the defense to complete all final requirements (revisions and upload to ProQuest) except when defenses are scheduled late in the semester and are subject to a deadline date that is shorter than 60 calendar days. Review the School’s academic calendar to be aware of deadline dates.

Exit Interview with the Dean

After your defense, and most likely after the final thesis is submitted to ProQuest, you will meet with the Dean for an exit interview. The meeting is intended as an opportunity for you to share your graduate school experiences with the Dean. This is a confidential meeting at which you may express your comments and discuss your concerns openly and honestly.

Department/Program Requirements prior to Termination of Student Status

Each program has its own process for students who are ending their student status. Be sure to check with your Graduate program coordinator to determine if there is additional paperwork that you’ll need to complete before your student status is terminated.

Publishing Your Final Thesis

The University of Rochester requires all doctoral candidates to deposit their theses for publication with ProQuest Dissertation Publishing and with the University libraries. Hard copies of the thesis are not required by the Dean’s Office or the Miner Library. Miner Library receives an electronic copy of the thesis from ProQuest but students must give the University their permission in writing to obtain it.

SMD graduate students are given 60 calendar days following the defense to submit the final copy of the thesis to ProQuest (except when a semester deadline does not allow 60 days for revisions).

For questions regarding publishing through ProQuest, contact Author Relations at [email protected] or +1 (800) 521-0600 ext. 77020.
For questions regarding University publishing, contact Jennifer McCarthy at 585-275-4603 , or jennifer_mccarthy@urmc.rochester.edu in the Miner Library.

Binding Your Final Thesis

Your department may want a bound copy of your thesis. Please check with your Graduate program coordinator to determine this and how the cost of binding is covered. You may also want a bound copy for yourself and others. Printed and bound color copies are available for purchase through ProQuest.

Date of Degree Completion

Degree requirements are met on the day your final thesis is submitted online to ProQuest.

Date of Degree Conferral

Conferral is the act of officially awarding a degree. The University of Rochester Board of Trustees confers degrees 5 times each year (August, October, December, February/March and May). Your conferral date will be determined by the date in which all degree requirements are completed and your final thesis is submitted to ProQuest.

PhD students can reference their specific conferral dates here .

Commencement

The graduation ceremony for all University of Rochester doctoral candidates is held in May of each year. Only the students that have completed degree requirements including the submission of the final thesis to ProQuest are eligible to participate in the ceremony. Diplomas are distributed at Commencement or mailed to those that do not attend.

Information on the Commencement Ceremony and graduation regalia can be viewed on the University Website or SMD GEPA website .

Proof of Completion

Many employers want “proof” of the degree earned. The Registrar can provide you with a letter indicating the date degree requirements were satisfied and the date the Board of Trustees will confer/conferred the degree. This is your best option for proof of degree immediately following graduate school.

You may also supply employers with your official transcript, which will be notated to include the date of degree conferral after conferral occurs. Your diploma can also be used as proof of the degree if you wish to copy it for an employer.

Some employers work with agencies that search for, screen and hire employees. They often submit forms to the academic institution that request enrollment information as well as degree verification. The Registrar will provide this information to an agency if your signature is provided with the forms indicating approval of the release of information.

Student Loans

If your student loans have been in deferment, you’ll need to notify your loan servicer of a completion date. Some loan servicers accept the completion date via your phone call while other servicers require that you submit a final loan deferment request form or letter from your Registrar before the repayment process can begin. Once a completion date is reported, your loan servicer will provide you with the information needed to start repayment or to continue deferred status, when applicable.

URMC Email Address

Student URMC email addresses will remain active for a short time after completion of the degree if the email address is hosted by the Miner Library. You can determine this by contacting the Miner Library email support or University IT . If you remain at the URMC after your defense, your email address will be transferred to a non-student server by the hiring department.

Non-URMC Email Address

You will be asked for a non-URMC email address when you submit your Exit Interview form. Correspondence from the Graduate Education and Postdoctoral Affairs Office will be directed to your non-URMC email address after your student status terminates. You will provide us with this email address on the Exit Interview Form.

Mailing Address

We ask that you provide a forwarding address so that we may mail Commencement and other correspondence to you. If you move again, please remember to update us. We want to keep in touch with you as you move ahead in your career. You will provide us with this address on the Exit Interview Form.

To ensure you receive end-of-year tax-related documentation, please update your mailing address in HRMS . Questions about updating your address in HRMS may be addressed to [email protected] .

Stay in Touch

Please provide us with your whereabouts so we can keep in touch, cheer you on your way up the career ladder, and provide you with useful, up-to-date information about professional development and about the School. Back to Top

Preparing for your thesis defence

As you start thinking about the end stages of your PhD, it’s important to understand the processes and timelines related to the thesis defence.

Even if your defence feels far away, there are steps you can take early on in order to ensure that the end of your PhD and defence process runs smoothly.

Jump to: What is a PhD defence? | Who's at the defence? | What happens at the defence? | What are the possible outcomes of the defence?

What is a PhD defence?

The thesis defence is a unique opportunity to share with other experts what you did as part of your PhD research, what you found or discovered, and why it’s important. Although there are a lot of regulations guiding the defence process, remember that this process is really about you and your work.

Goals of the PhD defence:

Allow you to show your mastery of the subject matter
Prove you are the author of the world
Demonstrate your ability to engage in scholarly discourse in your research area

Who's at the PhD defence?

The primary attendees of your PhD defence are the Chair of the defense and your examining committee. The Chair is an impartial faculty member from outside your department who is well-versed in the rules and proceedings of thesis examinations. The Chair does not question you and does not assess your work.

Examining committee:

Supervisor(s) - Your thesis supervisor(s) that have supervised your research.
Internal member - A member of your department; typically part of your advisory committee.
Internal/external member - An "internal" member of the university, but "external" to your home department. This person has suitable knowledge of the subject matter, even though they are from another discipline.
Additional member - Typically a member from your advisory committee.
External examiner - A person with a doctoral degree and expertise in the subject matter who evaluates the thesis from a fair an impartial perspective.

At University of Waterloo, it is also standard to have defences open to the public, so you can invite your friends, family and colleagues to be there! Check with your department to figure out what options are available to you.

In some cases, such as when there are intellectual property concerns, a closed thesis examination can be requested. This means that all those in attendance at the thesis examination, including the examining committee members, must sign a non-disclosure agreement. Closed examinations must be requested as early as possible.

What happens at the defence?

The first component of the defence is the welcome. The Chair will open up the defence, go over the order of proceedings, introduce the examining committee, and welcome the attendees.

After the welcome, the examination will formally begin with your oral presentation. The presentation is no more than 30 minutes, but the exact length and format can vary by department or discipline. It's best to check with your supervisor to confirm departmental expectations, but overall, the presentation should focus on your main contributions and conclusions.

The final component of the defence is the questioning period. This is not meant to be an interrogation, rather, a discussion amongst colleagues about the subject of your thesis.

The examination Chair monitors the question period, which goes in "rounds".
During the first round of questioning, each committee member will have 15 minutes to ask their questions, provide their comments, and discuss these with you.
After each committee member has had their turn to ask questions, there may be additional rounds for more questions. The Chair and committee decide when the questions will end.
Typically, the Chair will reserve some time at the end to accept questions from non-committee members.

While there is no set time for defences at the University of Waterloo, they typically range from 2-3 hours.

What are the possible outcomes?

Once your formal defence has concluded, the examination Chair will arrange for a private deliberation between the committee members. The examination committee's decision is ultimately based on your written thesis, as well as your ability to defend it, as the decision is determined by a majority vote.

In the event of a tie decision, or if the external examiner's vote is not in the majority, the decision will be deferred to the Associate Vice President (AVP), Graduate Studies and Postdoctoral Affairs. The AVP will consult the Faculty Associate Deans and come to a final decision.

Once the deliberation has concluded, the Chair will inform you of your examining committee's decision.

There are three possible outcomes to a PhD defence:

Accepted: The thesis is completed to the satisfaction of the examining committee. There may still revisions required, but they are likely minor and typographical or editorial in nature. In this case, you would have one month to complete all revisions and submit your approve thesis to UWspace.
Accepted conditionally: The oral defence and the thesis are acceptable, but content changes are required that are time intensive. In this case, you would have four months to complete revisions to the approval of your committee and submit the final version to UWspace. A re-examination is not required.
Re-examination: The oral defence is not to the satisfaction of the committee and/or substantial changes to the thesis are required. In this case, the candidate must be re-examined within 1 year.

Re-examination is very rare, and the vast majority of candidates have their thesis accepted at their first examination.
