At the pinnacle of this academic odyssey lies the PhD defence—a culmination that transcends the boundaries of a mere formality, symbolizing the transformation from a student of a discipline to a recognized contributor to the academic tapestry.

The PhD defence, also known as the viva voce or oral examination, is a pivotal moment in the life of a doctoral candidate.

PhD defence is not merely a ritualistic ceremony; rather, it serves as a platform for scholars to present, defend, and elucidate the findings and implications of their research. The defence is the crucible where ideas are tested, hypotheses scrutinized, and the depth of scholarly understanding is laid bare.

The importance of the PhD defence reverberates throughout the academic landscape. It is not just a capstone event; it is the juncture where academic rigour meets real-world application. The defence is the litmus test of a researcher’s ability to articulate, defend, and contextualize their work—an evaluation that extends beyond the pages of a dissertation.

Beyond its evaluative nature, the defence serves as a rite of passage, validating the years of dedication, perseverance, and intellectual rigour invested in the research endeavour. Success in the defence is a testament to the candidate’s mastery of their subject matter and the originality and impact of their contributions to the academic community.

Furthermore, a successful defence paves the way for future contributions, positioning the scholar as a recognized authority in their field. The defence is not just an endpoint; it is a launchpad, propelling researchers into the next phase of their academic journey as they continue to shape and redefine the boundaries of knowledge.

In essence, the PhD defence is more than a ceremonial checkpoint—it is a transformative experience that validates the intellectual journey, underscores the significance of scholarly contributions, and sets the stage for a continued legacy of academic excellence. As we navigate the intricacies of this process, we invite you to explore the multifaceted dimensions that make the PhD defence an indispensable chapter in the narrative of academic achievement.

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.

Defending Your Dissertation: A Guide

A woman in front of a bookshelf speaking to a laptop

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

If you want to learn more about dissertations in your own discipline, don’t hesitate to reach out to graduates from your program and ask them about their experiences.

How to prepare an excellent thesis defense

Thesis defence

What is a thesis defense?

How long is a thesis defense, what happens at a thesis defense, your presentation, questions from the committee, 6 tips to help you prepare for your thesis defense, 1. anticipate questions and prepare for them, 2. dress for success, 3. ask for help, as needed, 4. have a backup plan, 5. prepare for the possibility that you might not know an answer, 6. de-stress before, during, and after, frequently asked questions about preparing an excellent thesis defense, related articles.

If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

  • Check with your department about requirements and timing.
  • Re-read your thesis.
  • Anticipate questions and prepare for them.
  • Create a back-up plan to deal with technology hiccups.
  • Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

  • your presentation of around 20-30 minutes
  • questions from the committee
  • questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

  • preparing the room of the day of defense
  • setting up equipment for the presentation
  • preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

  • Try meditational breathing right before your defense.
  • Get plenty of exercise and sleep in the weeks prior to your defense.
  • Have your clothes or other items you need ready to go the night before.
  • During your defense, allow yourself to process each question before answering.
  • Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

  • Dress for success.
  • Ask for help setting up.
  • Have a backup plan (in case technology fails you).
  • Deal with your nerves.

Days, weeks, months, and probably years of practice to complete your doctorate, needs to surpass the dissertation defense hurdle.

In this article, we will discuss details of how to excel at PhD dissertation defense and list down some interesting tips to prepare for your thesis defense.

Table of Contents

What Is Dissertation Defense?

Dissertation defense or Thesis defense is an opportunity to defend your research study amidst the academic professionals who will evaluate of your academic work. While a thesis defense can sometimes be like a cross-examination session, but in reality you need not fear the thesis defense process and be well prepared.

What are the expectations of committee members.

Choosing the dissertation committee is one of the most important decision for a research student. However, putting your dissertation committee becomes easier once you understand the expectations of committee members.

The basic function of your dissertation committee is to guide you through the process of proposing, writing, and revising your dissertation. Moreover, the committee members serve as mentors, giving constructive feedback on your writing and research, also guiding your revision efforts.

The dissertation committee is usually formed once the academic coursework is completed. Furthermore, by the time you begin your dissertation research, you get acquainted to the faculty members who will serve on your dissertation committee. Ultimately, who serves on your dissertation committee depends upon you.

Some universities allow an outside expert (a former professor or academic mentor) to serve on your committee. It is advisable to choose a faculty member who knows you and your research work.

How to Choose a Dissertation Committee Member?

  • Avoid popular and eminent faculty member
  • Choose the one you know very well and can approach whenever you need them
  • A faculty member whom you can learn from is apt.
  • Members of the committee can be your future mentors, co-authors, and research collaborators. Choose them keeping your future in mind.

How to Prepare for Dissertation Defense?

dissertation defense

1. Start Your Preparations Early

Thesis defense is not a 3 or 6 months’ exercise. Don’t wait until you have completed all your research objectives. Start your preparation well in advance, and make sure you know all the intricacies of your thesis and reasons to all the research experiments you conducted.

2. Attend Presentations by Other Candidates

Look out for open dissertation presentations at your university. In fact, you can attend open dissertation presentations at other universities too. Firstly, this will help you realize how thesis defense is not a scary process. Secondly, you will get the tricks and hacks on how other researchers are defending their thesis. Finally, you will understand why dissertation defense is necessary for the university, as well as the scientific community.

3. Take Enough Time to Prepare the Slides

Dissertation defense process harder than submitting your thesis well before the deadline. Ideally, you could start preparing the slides after finalizing your thesis. Spend more time in preparing the slides. Make sure you got the right data on the slides and rephrase your inferences, to create a logical flow to your presentation.

4. Structure the Presentation

Do not be haphazard in designing your presentation. Take time to create a good structured presentation. Furthermore, create high-quality slides which impresses the committee members. Make slides that hold your audience’s attention. Keep the presentation thorough and accurate, and use smart art to create better slides.

5. Practice Breathing Techniques

Watch a few TED talk videos and you will notice that speakers and orators are very fluent at their speech. In fact, you will not notice them taking a breath or falling short of breath. The only reason behind such effortless oratory skill is practice — practice in breathing technique.

Moreover, every speaker knows how to control their breath. Long and steady breaths are crucial. Pay attention to your breathing and slow it down. All you need I some practice prior to this moment.

6. Create an Impactful Introduction

The audience expects a lot from you. So your opening statement should enthrall the audience. Furthermore, your thesis should create an impact on the members; they should be thrilled by your thesis and the way you expose it.

The introduction answers most important questions, and most important of all “Is this presentation worth the time?” Therefore, it is important to make a good first impression , because the first few minutes sets the tone for your entire presentation.

7. Maintain Your Own List of Questions

While preparing for the presentation, make a note of all the questions that you ask yourself. Try to approach all the questions from a reader’s point of view. You could pretend like you do not know the topic and think of questions that could help you know the topic much better.

The list of questions will prepare you for the questions the members may pose while trying to understand your research. Attending other candidates’ open discussion will also help you assume the dissertation defense questions.

8. Practice Speech and Body Language

After successfully preparing your slides and practicing, you could start focusing on how you look while presenting your thesis. This exercise is not for your appearance but to know your body language and relax if need be.

Pay attention to your body language. Stand with your back straight, but relax your shoulders. The correct posture will give you the feel of self-confidence. So, observe yourself in the mirror and pay attention to movements you make.

9. Give Mock Presentation

Giving a trial defense in advance is a good practice. The most important factor for the mock defense is its similarity to your real defense, so that you get the experience that prepares for the actual defense.

10. Learn How to Handle Mistakes

Everyone makes mistakes. However, it is important to carry on. Do not let the mistakes affect your thesis defense. Take a deep breath and move on to the next point.

11. Do Not Run Through the Presentation

If you are nervous, you would want to end the presentation as soon as possible. However, this situation will give rise to anxiety and you will speak too fast, skipping the essential details. Eventually, creating a fiasco of your dissertation defense .

12. Get Plenty of Rest

Out of the dissertation defense preparation points, this one is extremely important. Obviously, sleeping a day before your big event is hard, but you have to focus and go to bed early, with the clear intentions of getting the rest you deserve.

13. Visualize Yourself Defending Your Thesis

This simple exercise creates an immense impact on your self-confidence. All you have to do is visualize yourself giving a successful presentation each evening before going to sleep. Everyday till the day of your thesis defense, see yourself standing in front of the audience and going from one point to another.

This exercise takes a lot of commitment and persistence, but the results in the end are worth it. Visualization makes you see yourself doing the scary thing of defending your thesis.

If you have taken all these points into consideration, you are ready for your big day. You have worked relentlessly for your PhD degree , and you will definitely give your best in this final step.

  • 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.

The Last Big Hurdle: How to Prepare for a Successful PhD Defence

It’s the moment almost everyone who completes a PhD both dreads and looks ahead to for years—the defence. It signals a major achievement, but in people’s imaginations, it can seem like the stuff of nightmares… standing frozen in front of everyone, unable to answer a tricky question posed by a committee member and feeling like you must look incompetent. The format of a doctoral defence varies from field to field, but the worst fears of the candidates remain largely the same. Though most people know it probably won’t go so badly, the open-ended-ness can certainly be intimidating- you’re up there alone in front of a panel of experts who get to ask you whatever they’d like, and you may have to deliver your answers in front of an audience of your peers. There are few experiences in academic life more geared to be stressful for the person at the centre of them.

It doesn’t have to be that bad. I spent the weeks leading up to my PhD defence in a state of near panic, but I can honestly say that once it actually got underway, I sort of enjoyed it. You’re the star of the show and get to walk your peers through the finer points of your research. It can be a really invigorating experience. So let’s try to break this down into bite-sized chunks and look at strategies and tips for making your defence an event you might actually look back fondly on.

What the committee wants

Let’s start with what the committee is actually looking for. They want to see a firm grasp of the subject matter, an understanding of the implications of the work, and the ability to see weaknesses in the methodology and possible routes to take for future work. This means creating a presentation that gives a clear, logical overview of your topic, the question you’re addressing, what you did, your results and conclusions, and where the research can go from here. Remember, your jury members are not out to get you. The questions you receive from them will generally fall under one of three headings- those that test your subject knowledge, those that clarify a confusing point, and those that arise from genuine curiosity. If your presentation does a good job of conveying your knowledge of your topic, you can expect more questions from the second and third categories, allowing you to think of the defense more as a conversation amongst experts than a test from on high.

How to prepare

Practice is obviously very important here. Once you’ve put your talk together, find a trusted friend or mentor (ideally, several of them) who knows your field to go through it with you. They can both help you to pare down unnecessary parts and point out logical leaps you may not have noticed because you’re so close to the subject matter. You also want this to be a person who will ask you tough questions and try to spot holes in your reasoning, so choose your test audience carefully. It can be tempting to spend a lot of time obsessing over your slides, trying to make them perfect, but there’s a lot of studying you’ll need to do to be ready for more tangential questions, so don’t lose too much time this way.

Even though you have lived and breathed your thesis topic for years, it’s a good idea to give your thesis a complete re-read just to make sure you really know what’s in there. It may have been months since you finished writing it, and parts may have gotten a little fuzzy since then. Make sure you know why you used the methodology that you did, be able to justify any conclusions you’ve made, and if there are mistakes, admit them openly at the defence and be able to talk about what you should have done differently—the committee isn’t looking for perfection, they’re looking for clear thinking and thorough consideration of methodology.

This is also a good time to review important topics that are peripheral to your work; this will allow you to answer some of the questions designed to test the limits of your broader knowledge of your field. One of the best pieces of defence preparation advice I’ve ever heard is to find out what each of your committee members’ professional interests are, and do a bit of reading on those topics. There’s a very good chance that they’ll ask you something that’s related to their own work, because that’s familiar ground to them, and you may be able to anticipate these questions this way.

Finally, though it’s less and less of a problem as technology improves, you’ll want to make very sure ahead of time that all your presentation gear works and connects properly to the display equipment in the room where your defence will be. No one wants to be running around at the last moment looking for a dongle they didn’t think they needed, or have their laptop’s battery run out partway through the defence. Check that your slides look the same way on the projection screen as they do on your computer- not cut off or too dark. It also doesn’t hurt just to spend time in the room in which you’ll be presenting, to get a feel for the place and see where everything will be positioned.

Common questions and ideas to think about

  • What makes your project original, and how does it answer a previously unanswered question? What have you contributed to the body of knowledge on this topic?
  • Why was this question important to ask? Why do we care about what your findings reveal? (Hint: “Just for the sake of knowing” is not an acceptable answer here.)
  • Did the focus of your project change over its course? If so, explain how and why.

Methodology

  • Why did you choose your methodological approach (including your statistical analyses)? Why is it superior to or more appropriate than all other methodologies?
  • Talk about the difficulties you experienced with your methodology and how you addressed them.
  • What are the limitations of your study design/methodology?
  • Explain how your data represent an appropriate source of measurement to address your question.
  • Is the amount of data gathered sufficient to address your question? Why or why not?
  • If you could do it again with unlimited time and funds, how would your methodology change?

Conclusions

  • What would you say is the most important “take-away” message of your work?
  • Does your work have wider implications for other disciplines in your field?
  • How do your conclusions support or contradict the existing literature?
  • Are there alternative ways your data could have been interpreted?
  • Speculate about what broader implications your research could have, but which aren’t addressed by your data, or were outside the scope of your project.
  • If you were to continue on with this area of research, what would you do next to further your results? Is there a closely related “spin-off” question that needs to be answered?
  • Propose an experimental design to test this related question. What results might you expect to see?
  • Where do you think this field of study is headed in the next five to ten years?

Tips, tricks, and stress management

  • Practice the first few minutes of your talk until you can do it on ‘autopilot’; this will give you a bit of time to relax into your presentation, get your thoughts in order, and begin talking more confidently.
  • If your defence is open to the public, ask a few supportive friends or colleagues to sit where you can easily make eye contact while you’re talking. Seeing a friendly, smiling face can be encouraging and help you to relax.
  • Don’t forget to review the newest literature in the weeks leading up to your defence—one or more important papers may have been published in your field since you wrote your thesis, and you’ll want to know about them.
  • Have a hard copy of your thesis on hand during the defence. It’s much faster to flip to a physical page when asked about a particular section of the text. If this really isn’t for you, be sure you have a quick way to move through pages on your computer.
  • Eat and drink the same things you normally would on the day of your defence. Your stomach may be extra sensitive in response to the stress, and you don’t want to surprise it with anything new. And go easy on the caffeine… jittery-ness will not help you to manage your stress!
  • Try to let your enthusiasm for your subject matter show; your audience will feel more positive about your talk if they can see that you really find the work fascinating.
  • It’s fine to take a moment to think about your answer before responding. The silence isn’t as long or as deafening as you think it is. And if you don’t know, just admit you don’t know—it’s okay to not know everything.
  • Dress well, but comfortably, and try to project confidence. If you can speak to your committee as a group of your peers, it will reflect well on your growth as a scientist in training- and demonstrate you are someone who deserves to be awarded their doctorate.
  • Don’t forget to publicly thank your advisor, your committee, and any other key people involved with your project for their time commitment and investment in your career.
  • When planning post-defence festivities, be aware that you may be more tired, both mentally and emotionally, than you expected. Don’t ask too much of yourself in the hours following the event.

A bit of encouragement

Above all, there are two things you need to remember while preparing for your defence. First, your advisor and committee would not have allowed you to proceed to this point if they didn’t think you were ready. They want to see you succeed and, altruism aside, it would reflect badly on them as well if you were to fail. Trust that they’ve made the right decision. Second, after years of delving into your little corner of the scientific world, no one knows your thesis topic better than you do—not even your committee. Marshall your facts and feel confident in knowing that on this topic, you’re the world expert.

Preparing for your PhD 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 so that your degree completion is not delayed. Even if your thesis defence seems far away, there are several planning considerations you can consider early on to help the end stages of your PhD go smoothly.

On this page you will find videos, tools, and information about what the PhD thesis defence is , timelines for the PhD thesis defence , and tips for a successful PhD thesis defence .

All PhD students should also ensure that they read the PhD thesis examination regulations and review the thesis preparation guidelines prior to their oral defence. If your thesis defence will be conducted remotely, you should also review the process for a remote thesis defence .

What is the PhD defence?

Understanding the purpose, processes and possible outcomes of the thesis defence can help you feel more prepared for the defence itself. In this video, you’ll learn about what the defence is, who’s there, what happens, and the deliberation and range of possible outcomes.

Transcript - Demystifying the thesis defence at University of Waterloo (PDF)

You may wish to learn more about some of the topics discussed in this video. Here are some helpful links to learn more:

Examination committee members (including the external examiner): Visit the PhD thesis examination regulations section on the  PhD thesis examining committee for more information about the committee members, including information about the external examiner and conflicts of interest.

  • Closed thesis defences and non-disclosure agreements: Visit the PhD thesis examination regulations section on guidelines for thesis examination without public disclosure for more information about closed thesis examinations.
  • Thesis defence decisions and outcomes: Visit the PhD thesis examination regulations section on  decisions for additional information about decisions and outcomes.
  • Thesis submission: Visit the thesis submission webpage for information about the thesis submission process, including approvals that must be obtained before submitting your thesis.
  • UWSpace: Visit the Library’s UWSpace webpage for information about what UWSpace is and how to submit, or deposit, your thesis to UWSpace.

Timeline to defence

Early planning considerations.

Well before your defence date, there are several considerations to think about that can help make the end stages of your degree go smoothly and ensure your defence date and degree completion are not delayed:

  • Being aware of formatting requirements will save you time on revisions later on – the last thing you want to be doing before submitting your thesis to UWSpace is updating page numbers or your table of contents! Consider using the Microsoft Word or LaTeX thesis template produced by Information Systems & Technology. 
  • The Dissertation Boot Camp can help you develop effective writing practices and strategies for completing your thesis, while the three-part Rock Your Thesis workshop series will provide practical guidance for planning, writing, revising, and submitting your thesis project. You can also book an individual appointment to do backwards planning with an advisor. They can help you utilize the planning tools most effectively, while providing hands-on guidance and feedback.  
  • If you are using third-party content, including your own previously published work in your thesis, or seeking intellectual property protection (for yourself or another involved party), there may be implications for your thesis or defence. Learn more about copyright for your thesis , and email [email protected] for help with copyright questions related to your thesis.
  • Depending on your departmental or discipline’s norms, you may require approval from your entire committee, or just your supervisor. Ensure you talk with your supervisor and/or committee early on to confirm processes and timelines, so you’re not surprised later.
  • Depending on your departmental or discipline’s norms, your supervisor may select an external examiner themselves, or they may seek your input. Talk to your supervisor early on about this process, as in some faculties the external examiner may need to be vetted and approved as early as the term before you wish to defend. Remember that there are conflict of interest guidelines around the appointment of the external examiner , and the PhD candidate should not be in communication with the external examiner prior to the defence.
  • A PhD thesis must be on display for a minimum of 4 weeks prior to the defence date. To accommodate, you may need to submit your thesis as early as 6-8 weeks prior to your defence. Review your faculty specific backwards planning tool for the thesis submission deadline in your faculty and learn more about the display period in the PhD thesis examination regulations.
  • After your successful thesis defence, you will likely have some required revisions to your thesis. It’s important to understand revision timelines , especially if you’re hoping to become “degree complete” before a tuition refund or convocation deadline. Find tuition refund and convocation deadlines in the important dates calendar .
  • Following your thesis defence, there are several steps to be taken before your final, approved thesis is accepted in UWSpace. Ensure that you’re aware of these thesis submission steps and timelines in advance.

Backwards planning tools

Graduate Studies and Postdoctoral Affairs, in collaboration with the Faculties, have prepared faculty specific backwards planning tools to help PhD candidates map out the timelines related to their thesis defence and degree completion.

Select your faculty below to download a PDF copy of the backwards planning tool. We encourage you to discuss your ideal timelines with your supervisor(s) and your department graduate program co-ordinator.

Oral Examinations

If you have questions about oral examinations, contact us at [email protected] .

Once your dissertation is nearing completion, it’s time to schedule your defense—your final oral examination.

You should begin making arrangements for your defense at the beginning of the semester (especially during the summer) in order to accommodate the schedules of your committee members.

Students must be currently enrolled in the dissertation course for the semester in which the defense is scheduled and held.

Committee Changes

Any changes to your dissertation committee must be approved by the Dean of the Graduate School. Changes should be approved at least 30 days prior to the date of the oral examination so that all new members have ample time to become familiar with your dissertation.

Defense Attendance

You, the student, and your supervisor, in negotiation with the dissertation committee members, should determine a time and date for the defense. Each member of your committee must receive a copy of your dissertation at least four weeks prior to your dissertation defense date. A defense cannot be held within two weeks of the last class day of the semester, unless the committee has consented to hold the defense within those last 2 weeks.

Request for Final Oral Examination Form

You must schedule the dissertation defense with the Graduate School at least two weeks prior to the defense date by completing the Request for Final Oral Examination form. All members of your committee must sign your request form indicating their intent to be present at your final oral. Your graduate adviser must also sign this form to indicate you have been approved to defend.

It is expected that all members of the committee attend the defense. The Graduate School does not distinguish between physical attendance or electronic/virtual attendance of the defense. One non-supervisory committee member may be absent from the defense in if necessary, but all members must read the dissertation and, when satisfied, sign the Report of Dissertation Committee form.

Contact for Questions

Email the Graduate School at the link above with any questions concerning defense attendance.

Format Check Requirements

When you submit the Request for Final Oral Examination form to the Graduate School, you should include one copy each of the dissertation abstract, title page and the committee membership page for a format check in separate PDF. You do not need to include the instructions page.

After the Defense

The official recommendation of your committee and your program is communicated to the Graduate School on the Report of Dissertation Committee. The Dean of the Graduate School depends on this document to determine your eligibility to receive the doctoral degree so it is essential that it be completed and returned in a timely fashion. A passing report signifies that your committee unanimously agrees that you have completed a dissertation that is an independent investigation in your major field.

In the event that revisions to your dissertation are necessary before your committee members approve your dissertation, the report will be retained by your supervisor until all revisions have been completed. After successful completion of your defense and any required revisions to your dissertation, the Report of Dissertation Committee should also be signed by all members of your committee and must be submitted to the Graduate School.

After you’ve made required or requested revisions to your dissertation, if any, check it carefully for grammar, spelling, punctuation, content and format, then convert it to the required PDF format and upload it.

Do not submit your report/thesis/dissertation via email . Final reports, theses and dissertations MUST be uploaded to the Texas Digital Library before your final paperwork and pages will be reviewed. After submission, no revisions or corrections will be allowed except for those required by the dean of the Graduate School.

Upcoming Oral Examinations

Doctoral students’ final oral examinations are open to all members of the University community and the public unless attendance is restricted by the Graduate Studies Committee. Scheduled oral examinations are published on the UT Grad School website.

Defense and Dissertation Overview

Once a student’s box is checked, the BPH student should set up a one-on-one “Defense Packet Meeting” with the BPH Associate Director to review the Defense and Dissertation Process, which includes reviewing all required materials, logistics, timing, FAS/Harvard Griffin GSAS Form of the Dissertation, sample forms, and to answer student questions related to these processes.

how long is phd defense

  • Defense Committee Chair: One member of the student’s DAC, often the DAC chair, is required to chair the oral defense. This required holdover from the DAC serves the purpose of providing insight to the examiners regarding the path the student has taken in completing the dissertation research. Their primary role is to assess committee satisfaction with the written dissertation, administer the exam, arbitrate any problems that may arise, and make final recommendations for completion of necessary corrections and additions to the dissertation. No other DAC members can serve on the defense committee .
  • At least one member must be a BPH faculty member, often from the same academic department.
  • One member of the examination committee must be from outside of Harvard University.
  • The fourth member may be from either BPH or another Harvard-affiliated program.
  • Co-authors and collaborators cannot be members of the Defense committee
DEFENSE TIMING AND FORMAT
  • Students should notify the BPH Program as far in advance as possible with the details of the exam. 
  • The student is required to notify the BPH office no later than 3 weeks in advance of the defense with the final dissertation title.
  • At least two weeks before the date of exam, defense members should be sent copies of the dissertation for review. A copy of the dissertation should also be sent to the BPH program.
  • If any defense committee member foresees problems with the exam, they should contact the chair of the defense committee in advance of the meeting. If major problems are found with the written document, the Committee can decide to postpone the oral defense until satisfactory changes are made. While rare in our program, these occasions can involve the insufficient or improper use of statistical methods, grossly overstated conclusions, insufficient background or discussion, or evidence of plagiarism.
  • More details about the timing and format are provided in the “Defense Packet Meeting” held with each student.

STIPEND GUIDELINES

If a student successfully defends the dissertation before the 15th of the month, the stipend will be terminated at the end of that month. If the student successfully defends on or after the 15th, the next month’s stipend will be the final month the student is paid, at the discretion of their advisor.

Students are encouraged to speak to their advisors directly about how they should be paid as they complete their graduate work. If an advisor wishes to pay the student for one additional month, beyond what has been explained above, the advisor must notify the department’s financial administrator. For administrative reasons, a stipend cannot be issued to a student after their graduation/degree conferral date.

ORAL DEFENSE PROCEDURES

Part 1: Public Seminar As part of the exam, the PhD candidate will present a public seminar followed by a private oral examination.  The public presentation lasts no longer than 1 hour, which includes time for the advisor’s introduction, the student’s oral presentation and acknowledgements, and time for audience questions and answers.  The Defense Committee is required to attend the public seminar; however, it is customary for members of the defense committee to hold their questions until the private oral exam.

Part 2: Private Oral Examination A private oral examination follows the public seminar.  Initially, the student will be asked to leave the room for several minutes, along with the dissertation advisor if the dissertation advisor has decided to remain for the private exam.  During this time, the committee will discuss the merits of the dissertation, any issues with the dissertation, and areas they may want to focus on during the oral exam.  The student (and advisor if present) is then asked back into the room for the exam.

Each member of the defense committee will direct questions to the candidate based on their review of the dissertation and presentation of the seminar. The Defense Chair will moderate the discussion between the panel and the student.  The closed defense takes up to two hours and involves detailed technical questions as well as broader questions on the conclusions, impact, and limitations of the research.  Dissertation advisors may be present, but they must not participate in the exam (e.g., answer questions posed by the committee).

At the end of the examination, the student (and advisor if present) is once again asked to step out of the room for several minutes.  The Committee will discuss any revisions needed for the thesis and whether these revisions need to be reviewed and by whom.  Once the committee determines the outcomes, the student will be asked back into the room and the Committee provides the student with any [minor] changes needed to the dissertation. While it is extremely rare for the student to fail at this stage, the committee will provide recommendations to the student on their research, communication skills, and development as a scientist, as well as delineating the required changes to the dissertation.

PREPARING FOR THE DEFENSE/WRITING THE DISSERTATION

Students preparing to write and defend their dissertation must review University requirements as outlined in “ Dissertations ” with guidelines published at the Graduate School of Arts and Sciences.

Students are also welcome to visit the BPH Student Lounge (Building 2, Room 113) to look at copies of previous BPH bound dissertations.

Writing the Dissertation Each student must write a comprehensive PhD dissertation on their research topic and the original results of their research. There are a variety of ways a dissertation can be composed, but the core elements described below must be included. The dissertation must show original treatment of the subject, contain a scholarly review of the pertinent literature, provide evidence of independent research of publishable quality, and be clearly, logically, and carefully written. In addition to a compendium of the student’s research, including detailed methods and results, the dissertation must contain a thoughtful discussion of the conclusions, impact, and limitations of the research. The completed work should be critically reviewed by the dissertation advisor before being submitted to the Dissertation Defense Committee.

In some cases, the student has done all of the work in the dissertation; more often portions of the dissertation result from collaborative research. In all dissertations containing collaborative results, the dissertation should indicate concisely who contributed to the work and how.  For example, a chapter containing multi-authored, published work must include a complete reference of the publication and a brief description of the candidate’s and the colleagues’ contributions. For work that is not published but which resulted from multiple researchers, the contributors must be named and respective attributions made clear. This policy allows stylistic flexibility; depending on the amount of collaborative work in the dissertation and the status of publication(s), the attributions can be, preferably, on or accompanying the cover page for each chapter or within an extended acknowledgements section at the end of each chapter. It is recommended that if figures or figure panels are included that are the work of others that the figure panels be clearly identified and the work properly attributed. It is permissible for more than one student to include work from the same collaboration or publication as long as the required attributions are clear, justified, and complete.

Individual chapters can be that of published articles as long as there are also comprehensive Introduction and Conclusion chapters written by the student. While the text can be the same, use of journal reprints as a chapter is not permissible. A word document of the published article must be used, and the pages in the dissertation must be consecutively numbered. Furthermore, the figures and accompanying figure legends must be integrated into the main body of each chapter, preferably following the first mention of the given figure, not clustered at the end of the chapter. Any dissertation that varies significantly from the Graduate School or FAS guidelines, or is not neat and readable, is subject to required stylistic revision before acceptance by the University. (For further information, please visit https://gsas.harvard.edu/academics/dissertations ).

DEFENSE FORMS AND PAPERWORK

Dissertation Acceptance Certificate Before the examination, the BPH Program Office will provide the Defense Committee Chair with a copy of the official Dissertation Acceptance Certificate. This certificate must be signed by all readers of the dissertation at the end of the examination and returned to the BPH Program Office. This certificate will be scanned and sent to the student so it can be inserted as page one of the dissertation prior to the online submission. The student must submit the one original, official copy to the Registrar’s in Cambridge by the appropriate deadline.

If extensive corrections are to be made, the BPH Program Office will hold the certificate until the Defense Committee Chair, and/or assigned reviewer(s) provide a written notification to the BPH Program to confirm that the corrected work has been reviewed and approved.

Dissertation Defense Exam Report The Dissertation Defense Exam Report is completed by the members of the Dissertation Defense Committee to provide a record of any comments or recommendations they may have. The report must be signed by all members immediately after the private exam. The completed report must be submitted to the BPH Program Office at the same time as the Dissertation Acceptance Certificate.

Top 7 tips for your defense presentation

1. show why your study is important, remember, your audience is your committee members, researchers in other fields, and even the general public. you want to convince all of them why you deserve a ph.d. degree. you need to talk about why your study is important to the world. in the engineering field, you also need to talk about how your study is useful. try to discuss why current practice is problematic or not good enough, what needs to be solved, and what the potential benefits will be. , see how dr. posen and dr. malings explained the importance of their studies..

  • Carl Malings Defense Slides with Notes
  • I. Daniel Posen Defense Slides with Notes

2. Emphasize YOUR contribution 

Having a ph.d. means that you have made some novel contributions to the grand field. this is about you and your research. you need to keep emphasizing your contributions throughout your presentation. after talking about what needs to be solved, try to focus on emphasizing the novelty of your work. what problems can be solved using your research outcomes what breakthroughs have you made to the field why are your methods and outcomes outstanding you need to incorporate answers to these questions in your presentation. , be clear what your contributions are in the introduction section; separate what was done by others and what was done by you. , 3. connect your projects into a whole piece of work, you might have been doing multiple projects that are not strongly connected. to figure out how to connect them into a whole piece, use visualizations such as flow charts to convince your audience. the two slides below are two examples. in the first slide, which was presented in the introduction section, the presenter used a flow diagram to show the connection between the three projects. in the second slide, the presenter used key figures and a unique color for each project to show the connection..

  • Xiaoju Chen Defense Slides with Notes

4. Tell a good story 

The committee members do not necessarily have the same background knowledge as you. plus, there could be researchers from other fields and even the general public in the room. you want to make sure all of your audience can understand as much as possible. focus on the big picture rather than technical details; make sure you use simple language to explain your methods and results. your committee has read your dissertation before your defense, but others have not. , dr. cook and dr. velibeyoglu did a good job explaining their research to everyone. the introduction sessions in their presentations are well designed for this purpose. .

  • Laren M. Cook Defense Slides with Notes
  • Irem Velibeyoglu Defense with Notes

5. Transition, transition, transition

Use transition slides to connect projects , it's a long presentation with different research projects. you want to use some sort of transition to remind your audience what you have been talking about and what is next. you may use a slide that is designed for this purpose throughout your presentation. , below are two examples. these slides were presented after the introduction section. the presenters used the same slides and highlighted the items for project one to indicate that they were moving on to the first project. throughout the presentation, they used these slides and highlighted different sections to indicate how these projects fit into the whole dissertation. .

You can also use some other indications on your slides, but remember not to make your slides too busy.  Below are two examples. In the first example, the presenter used chapter numbers to indicate what he was talking about. In the second example, the presenter used a progress bar with keywords for each chapter as the indicator. 

how long is phd defense

Use transition sentences to connect slides 

Remember transition sentences are also important; use them to summarize what you have said and tell your audience what they will expect next. if you keep forgetting the transition sentence, write a note on your presentation. you can either write down a full sentence of what you want to say or some keywords., 6. be brief, put details in backup slides , you won't have time to explain all of the details. if your defense presentation is scheduled for 45 minutes, you can only spend around 10 minutes for each project - that's shorter than a normal research conference presentation focus on the big picture and leave details behind. you can put the details in your backup slides, so you might find them useful when your committee (and other members of the audience) ask questions regarding these details., 7. show your presentation to your advisor and colleagues, make sure to ask your advisor(s) for their comments. they might have a different view on what should be emphasized and what should be elaborated. , you also want to practice at least once in front of your colleagues. they can be your lab mates, people who work in your research group, and/or your friends. they do not have to be experts in your field. ask them to give you some feedback - their comments can be extremely helpful to improve your presentation. , below are some other tips and resources to design your defense presentation. .

Hints for PhD Defenses

At Columbia, PhD defenses are generally not public, although CS usually allows a student audience. Defenses consist of four parts: first, the candidate introduces themselves, then presents a summary of their work, interrupted and followed by questions from the committee. Finally, the committee meets in private to discuss the presentation and dissertation.

While most of the committee will have read most of your thesis, you cannot assume that everyone has read every chapter.

The committee needs to be able to assess impact and depth. Usually, the committee has some idea of this before the defense, but whatever the student can say to make this assessment easier, perhaps just through emphasis, is likely to make the defense go much more smoothly.

Generally, the whole defense will not take more than two hours, but should take considerably less time. Part of the challenge of a defense is to convince the committee that you can summarize the important points of your work in a very limited time.

  • What is the problem you are studying?
  • Why is it important ?
  • What results have you achieved?
  • Some committee members will want to know if the works has been published and where and how it was received. For example, if you have written software, indicate where it is being used, either for follow-on work or in some production or test environment.
  • Have a list of your thesis-related publications as a slide. Indicate any awards that a paper may have received. For most people, it's easier to list some honor than "brag" about it in person.
  • If you have presented your work in a conference or at job talks, be sure to anticipate and address the most common questions asked there.
  • The committee should be handed a copy of your slides.
  • Be prepared to briefly summarize your background (undergraduate degree, how long at the university, etc.)
  • No more than 30 slides, plus "back up" slides with additional material in case of questions. The most effective way of making your committee members mad is to come unprepared with a stack of 80 slides and then madly skip through them.
  • Number your slides, particularly if one of your committee members is linked in via speakerphone. Consider using some kind of remote presentation software.
  • List your contributions early.
  • When presenting your contributions, be sure to use "I" and not "we" so that the committee will know what aspects of the work where yours, and which were group projects.
  • Keep discussions of related work very brief, but be prepared to answer questions of the "how does this differ from so-and-so's work" succinctly.
  • You will not be asked to prove results again.
  • Be prepared to back up any comparative statement with facts, in particular statements like "works better", "faster", "scalable" or "optimal". If you are presenting a protocol, how do you know that it works correctly?
  • If you have multiple parts in your dissertation, consult with the committee ahead of time as to whether it makes sense to omit some of them for the presentation.

Hints for Dissertations

  • It is better to focus deeply on a single area then to work on several topics, each of which is pursued to a moderate depth.
  • Systems work must be coupled with implementation and some kind of numerical comparitive analysis to demonstrate the improvements from existing or alternate approaches.
  • Your thesis needs a one page executive summary that a layperson should be able to understand. Test: give it to a relative of yours that does not have an engineering degree...

Miscellaneous Hints

  • You are likely only to defend a PhD thesis only once; your defense is a special occasion, so consider dressing appropriately, at least business casual, but a suit is not inappropriate.
  • It is customary to provide refreshments for the audience, such as coffee, bagels, cookies and fruit, depending on the time of day.

The Role of PhD Committee Members

  • Committee members (should) read the draft thesis (and provide feedback). Obviously, students appreciate an in-depth reading, but it is common for committee members to focus on chapters closest to their expertise. Reading depths varies - some provide line edits, others just suggest larger issues that should be addressed ("Your related work section in Chapter 10 is a bit sparse and ends in 2005."). While this is probably not the place to suggest "do another year of research", filling in gaps is ok and I'd rather postpone a defense by a month if needed. Before the committee gets the thesis, I've done a first or sometimes second reading, but the whole point of the committee is to keep the advisor honest (and complement his or her knowledge or taste).
  • Committee members attend the PhD defense, usually in person. Typically, this lasts about 90 minutes. Take notes on any editorial improvements (e.g., "make clear that the throughput graph is measured in gallons/minute"). Vote on the outcome and sign the form.
  • If the student is given a set of changes to implement, the advisor asks students to detail on how they implemented the changes, similar to how an author may respond to reviewer comments for a journal. The committee informally signs off, or not, on these changes. There is no need to re-read the thesis.

Checklist for Dissertation

  • Spell check;
  • Check for missing chapter or figure references;
  • Section, Chapter, Figure are capitalized;
  • All references converted from [1][2][3] to [1,2,3];
  • Consistent capitalization in captions;
  • Verify expansion of all abbreviations at first instance;
  • Avoid "tremendous", "huge" and other similar adjectives;
  • End to end -> end-to-end;
  • Check references for capitalization of abbreviations and missing data such as page numbers.

Dissertation Committee

Dissertation defense process.

The dissertation defense is one of the most important moments in a graduate student’s career. When a student is deemed to be ready to defend the doctoral thesis, the student is the expert in a particular research area.  At the defense the student is expected to cogently and clearly explain their research and how it fits with other scholarship in the field of study. The exact nature of the oral defense may vary by discipline and department, so it is important that the student talk to the dissertation committee chair about what to expect and how to prepare.

The defense typically lasts about two hours and may be open to the public. The defense aims to accomplish two goals. First, it will provide an occasion for the presentation and recognition of the completed doctoral work. Second, it will furnish the opportunity for discussion and formal evaluation of the dissertation.

The timing of the defense will be set by the student in consultation with the dissertation committee. Students should contact their departments to schedule the dissertation defense. Note that some departments do not schedule examinations in summer. The student should send copies of the dissertation to the members of the committee no later than three weeks prior to the defense. The time and place of the defense shall be announced on the department’s calendar of events.  

The chair of the student's dissertation committee and at least one other committee member must be present in person. In the case that a committee member is unable to attend in person, the committee member may participate by Skype or other teleconference media. The defense must be open to all faculty within the department. Broader attendance will be left to the discretion of the student in consultation with the committee.

Please note: Departments will be allowed to have in-person defenses. Additionally, there is no reason to limit remote defenses if that is what the participants want and the department/committee approves. 

The dissertation defense shall be an open presentation by the student on the main aspects of the research reported in the dissertation, followed by questions, comments, and discussion. The chair of the dissertation committee or a designee shall act as the moderator of this discussion and shall have discretion to decide whether questions are germane to the topic of the dissertation. After discussion is completed, the departmental faculty in attendance and the dissertation committee will decide privately whether the dissertation defense has been satisfactory.

The dissertation chair or designee will report the results as soon as possible after the dissertation defense to the Dean of Students office by submitting a signed Report of Final Examination and a Dissertation Defense Form. If the manuscript is to undergo revisions, the student will be informed of the timeframe in which the revisions are to be completed.

Dissertation Submission

A final copy of the dissertation must be submitted following the procedure outlined on the  Dissertation Office  website by Friday of the seventh week of the quarter in which a student is graduating, sixth week in summer quarter. The defense should be held in sufficient advance of this deadline to allow revisions recommended by the student's dissertation committee.

Students should contact the Dissertation Office no later than early in the quarter in which they intend to graduate in order to resolve any questions or problems they may have in preparing the dissertation. The Dissertation Office staff is willing to look at a draft of the dissertation. Having them do so avoids both the expense and headache of having to re-format the dissertation. They offer a schedule to help students plan for a smooth process to meet these deadlines.

Additional requirements including where the dissertation must be submitted is available at: https://studentmanual.uchicago.edu/academic-policies/dissertation-requirements/

How Long Does it Take to Get a PhD?: A Go-Getter’s Guide to Graduation

Featured Expert: Dr. Charlene Hoi, PhD

How Long Does it Take to Get a PhD?

How long does it take to get a PhD? On average, PhD programs are 4 or 5 years long. The time it takes to get a PhD is slightly longer in the US, between 4-6 years, because these programs tend to be more structured. If you want to know how to get a PhD in Canada or Europe, you can expect it to take 3-5 years. However, there are PhD programs that take longer, such as part-time programs, or are extremely short, like online accelerated PhD programs. Ultimately, how long it takes to get a PhD is up to you. In this article, we’ll look at the average PhD program lengths, the typical PhD timeline, and tips on how to get your PhD finished faster.

How long does it take to get a phd.

On average, it takes 4-5 years to complete a Doctor of Philosophy (PhD) program. In the US, most PhD programs are between 4-6 years, while in Canada they are typically shorter, around 3-4 years.

Some students take longer than 6 years to complete their PhD, but in general the longest time it takes to get a PhD is capped at 8 years. If you’re enrolling in a part-time PhD program, for instance, your timeline will probably be extended to 6-8 years.

The shortest PhD programs out there are accelerated or sometimes online PhD programs. Some of these are only 1-2 years long, but there are comparatively fewer programs available, and they are only suitable for certain fields and careers which require less intensive research which defines most PhD programs.

One of the main reasons why it takes many years to get a PhD is because these programs are comprehensive and the requirements to graduate are extensive. Most have a set number of credit hours you need to complete, examinations to write, plus you’ll need to write your PhD thesis or dissertation, unless you pursue a PhD without dissertation .

There are certainly ways to shorten the PhD application timeline and time to graduate, which includes enrolling in a shorter program if possible, increasing your course load or the number of research hours you can dedicate per week, but generally a PhD will still take some time.

Even if you want to do a PhD without a master’s degree first, such as by applying to a direct entry PhD program, the program is still usually 4-5 years long.

We’ll take a look at the typical PhD timeline and how long it takes to get a PhD normally. After, we’ll cover some tips on how to get your PhD done faster or how you can avoid dragging things out.

In North America, the typical PhD program is divided into two stages. The first stage is where you complete all the required coursework, comprehensive exams and other academic requirements, depending on the program. The second stage is when you submit a proposal for original, independent research, get it approved and start working on your thesis or dissertation. Your PhD culminates with your thesis defense. Once your thesis has been approved, you’ll be eligible to graduate.

This timeline is somewhat flexible, as you might complete the first stage in 1 or 2 years but take longer to complete your dissertation. For the purpose of this general PhD schedule, we’ll assume your PhD program is a typical length of 4-6 years.

Application Stage

We’ve included the application stage of getting your PhD here first because the grad school application timeline can take several months to put together your application package and hear back about acceptance to a program. Secondly, because the application stage involves some critical steps you’ll need to complete in order to get your PhD.

1. Research proposal

To apply to a PhD program, you’ll most likely be required to submit a research proposal and be prepared to answer any research proposal questions your advisor will have. This is your “proposal” of what research question you will explore during your studies at a program, or an outline of what research topic you want to pursue. If you’re not sure how to write a research proposal, check out these Oxford PhD proposal samples or a Cambridge PhD proposal sample.

2. Application materials

The admission requirements for a PhD can vary from program to program, but here are the general components of a PhD application:

  • Required prerequisite coursework
  • Official transcripts (and minimum GPA)
  • Graduate school statement of purpose
  • CV for graduate school or research resume
  • PhD motivation letter

Some programs may also ask you to submit additional essays, such as a letter of intent, research interest statement or grad school career goals statement .

Many PhD programs also invite you to a grad school interview to get to know you better. Be ready for common graduate school interview questions such as “ tell me about yourself ” and “ why do you want to do a PhD ?”

Writing a grad school statement of purpose? Check out these examples:

PhD Years 1-3: Coursework Stage

1. orientation.

Your PhD program will usually begin with your orientation, where you’ll learn about the program’s individual structure, requirements and expectations. You’ll also either choose or be assigned an academic advisor and schedule an initial meeting with them. Your advisor will be a member of the university faculty who will act as your support while you complete your research and write your thesis.

2. Coursework

The first year or two of your PhD will involve completing required advanced coursework in your field. You’ll attend lectures and seminars and you may participate in research projects with department faculty or fellow graduate students or even lab work, depending on your field.

3. Electives

Along with required coursework, you’ll have the chance to take elective courses that interest you or relate to your field. It’s important to choose electives that will enrich your program. Choose ones that really interest you, that might help inform your PhD research or that will help you fulfill your credit requirements.

4. Extracurriculars

PhD programs sometimes have extracurricular activities or additional requirements outside the classroom. This can include internships or a practicum you need to complete for credit, or you might be interested in attending academic conferences or relevant events to socialize and network you’re your colleagues in the field.

5. Comprehensive exams

The coursework stage of your PhD program will end with comprehensive exams , sometimes called qualifying or preliminary exams. These are your “final exams” to make sure that you completed the necessary PhD coursework and that you’re ready and qualified to take on your own independent research in the next phase.

1. Thesis proposal

You may recall that you submitted a research proposal as part of your PhD application, and this step of the process is similar. Your thesis proposal is just like your research proposal, but it’s a more refined and developed version. Throughout your coursework, your research question might have changed or you might have changed course a little bit. If you’re still thinking about your PhD topic , take the time to solidify it before you reach the thesis proposal stage.

Your research proposal might have been a first draft, while your thesis proposal is your official announcement of: this is what I propose to research in this PhD program.

Depending on your field and the program, you thesis research might involve a great deal of lab work, or data collection or fieldwork. Whatever the case, your thesis proposal is a complete outline of what you intend to do for this independent research project and the steps you’ll take.

2. Thesis approval

Once your proposal is written, you’ll submit it for approval. Your academic advisor, PhD supervisor or the PhD committee overseeing your program will review it and either approve it or make suggestions for changes. Once it’s been polished and finalized, you’ll be given the go ahead to start conducting your research.

3. PhD research

Your research alone will probably take you several semesters to complete. On top of the fieldwork, lab work or data collection and analysis you’ll be completing, you’ll be using this time to write and review. Writing your thesis or dissertation takes a fair number of hours to outline, draft, edit and complete. It also means hitting the books to complete a literature review of your research topic so you have a complete background understanding of your chosen topic and how it will inform your research.

Your research and the preparation of your thesis is really the biggest part of this second stage, and is probably the longest part of your PhD altogether.

4. Extra requirements

When you’re not deep in your research, you’ll be completing other requirements of your PhD program or additional duties that enrich your education. Some programs require you to dedicate some hours to teaching, whether it be leading seminars for undergraduate students or acting as a teaching assistant for university faculty.

You’ll also be strongly encouraged to publish as a graduate student , so you may be involved in the research projects of faculty members or other grad students when you’re not working on your dissertation.

5. Thesis submission and preparation for thesis defense

When you’re finished writing your thesis and you’re ready to submit it, it’s critical to know how to prepare for thesis defense . Because not only do you have to complete this original, new body of research work, you have to get the approval of your PhD committee to put it out into the world.

Your thesis defense is essentially the final presentation of your PhD.

6. Thesis defense

Your thesis defense is an oral presentation of your research project, but it also involves submitting your written document to be reviewed. Essentially, you’ll present the entirety of your thesis to the PhD supervising committee, including your findings and conclusions. From there, the committee will ask thesis defense questions . Your answers will defend your methodology and results to the committee, basically proving the value and validity of your work. While this is an evaluation of sorts, it is also your opportunity to share your original ideas and invite further research into your topic.

After your defense, the PhD committee will either approve your thesis or send it back to you with edits or changes to be made before it can be formally approved.

Graduation and Postdoc

Once your thesis has been approved, congratulations! You’ll be eligible for graduation and be awarded your degree. Now that you’ve finished this marathon, you can choose to pursue further studies or start looking for a job after grad school .

With a PhD, you have many different options for positions in your field. You might want to know how to find a job in academia or how to get a tenure track position at a university if you’re interested in teaching others. PhD graduates who decide to transition from academia to industry or who would rather work outside the realm of academia can find industry jobs after PhD that suit their skills and experiences.

Either way, you’ll need to prepare for how to find a postdoc position, explore what the career options are for you, decide what your career goals are and start sending out applications. Remember to prep your postdoc resume and get read for postdoc interview questions , since the job hunt will begin soon after you finish your PhD!

Is it possible to get your PhD done faster? What are some ways you can speed up the process and avoid taking 8 years to complete your graduate studies? Luckily, there are many key ways you can make your journey through grad school easier and speed things up a little, from the type of PhD program you choose to the habits and skills you cultivate during your program.

#1 Enroll in an accelerated program

The first way to guarantee it will take less time to get your PhD is to, of course, enroll in a shorter PhD program. Direct entry PhD programs allow you to enroll once you’ve completed your bachelor’s degree in exceptional circumstances. Note that these are not the easiest PhD programs to get into , as your academic record needs to be excellent, and you’ll likely need prior research experience and you may even need to have publications already. However, a direct entry PhD program is around 4-5 years, but it allows you to skip the 1-2 years it would take to earn a master’s degree.

You can also choose to enroll in an online or accelerated PhD program that is designed to be much shorter than the traditional PhD. Once again, though, these programs are not available to students in every field, so you may need to research whether there are any options for you.

#2 Choose the right mentor

One of the first things you can do to ensure your PhD is smooth sailing is to choose the right mentor or academic advisor. Many programs allow you to choose your advisor, while some assign one to you. Whatever the case, it’s important to establish a strong working relationship and clear expectations early on.

One of the first things you’ll do as a PhD student is meet with your advisor. Take the time to discuss with them what your expectations for the program are, ask questions and ask them what their expectations are of you. Your advisor is there to help you and advise you, and they have resources and connections you can use to your advantage. But they are also working with a busy schedule and might be advising more than one PhD student, too. A mutually respectful relationship with open communication will ensure fewer interpersonal hurdles down the road.

#3 Earn credit hours faster

One way you can shave some time off your PhD is by earning your credit hours faster and getting to the research and thesis-writing stage faster. This might mean you take on a full-time course load or ask your advisor for ways to earn extra credit, such as participating in research projects. Some PhD programs will give you course credit for previous graduate level coursework you might have completed during your master’s degree, or for certifications and professional education you completed outside of school.

#4 Keep your thesis focused

When you get started on your research, it’s easy to feel overwhelmed with the amount of work you need to complete, with the writing of your thesis on top of it all. One way to keep your research hyper-focused and on point is to keep your thesis topic narrow. If your subject is too broad, you’ll be spending way too much time in your research. Give yourself clear objectives and scope, and don’t deviate from your PhD proposal if you don’t have to.

There may be a million questions you want to explore within your PhD topic, but there will be other opportunities to explore them. Keep your focus narrow so you don’t spend years and years asking and answering research questions!

One of the best things you can do to get your PhD done faster and adjust to the experience of graduate school is to change your thinking. Adopt a growth mindset so that you’re open to new learning, willing to listen to constructive feedback on your proposal or thesis and willing to grow your skills. A PhD is an advanced program, and you’ll already be very skilled, but it is also an opportunity to learn and grow. There will be challenges for you, so be ready to meet and overcome them instead of letting them draw you back or slow you down.

#5 Develop your professional skills fast

A PhD is an opportunity to grow your professional skillset as much as it is an opportunity for you to contribute meaningfully to your field. If you haven’t already been working on skills such as communication, presenting or lecturing and writing, now is the time to start.

Strong writing skills will help you get your thesis finished and edited faster, as you’ll be more familiar with the process and understand what makes a strong document. It’s also a useful skill to learn how to write effective funding proposals or grant proposals. You may need to do so to secure funding for your research, but it’s a highly valuable skill in the workforce, too.

Good presentation skills will help you during your thesis defense or if you’re asked to present during a conference. They will also help you build confidence in your voice and ideas and make you a better communicator when you’re networking or job searching.

#6 Keep to your schedule

This is maybe the most important skill if you want to finish your PhD faster: make a detailed schedule and hold yourself accountable to it. If you like, you can plan out your entire PhD week by week from Day 1. Write down what your course schedule is, when you’ll do research and how many hours, when you’ll write and how many hours, what extracurriculars or personal activities will take up your time and so on.

A detailed schedule gives you an overview of your PhD and a timeline of when you’ll finish. It will keep you organized and accountable, so you can avoid procrastinating or avoidable speed bumps that might slow you down. It also helps you compartmentalize the many items on your to-do list so you don’t stress out about how much you need to accomplish.

When creating your schedule, especially during the research stage when there is no formal class schedule for you to adhere to, focus on deliverables. Set a date when you will submit a section of your thesis to your advisor, or when you will complete your literature review. Setting goals and clear outcomes will keep you on track and focused.

#7 Take initiative and be independent

The last tip to help you get your PhD done faster is to take initiative. Remember that a PhD is a largely independent endeavor. You’ll have the support of a committee or advisor, but you can’t rely on them to do the work for you or put everything on hold if they aren’t available when you need them. Be flexible and adaptable so you can keep working and moving forward, even if your schedule gets interrupted or needs to change to suit your situation.

It's also important to take the initiative in your learning. Take advantage of opportunities for growth, networking, and gaining experience where you can. Get the most out of your PhD program and use your experiences to fuel your end goal of completing your thesis.

On average, it takes 4-5 years to get a PhD. There are a few factors that can influence the time it takes to complete your PhD, from program length and structure to what country you are earning your PhD in, to your own personal work ethic and schedule.

PhD programs in the US are on average 4-6 years. In Canada and the UK, they are usually 3-5 years long. Part-time PhD programs may take up to 7-8 years to complete. Direct-entry PhD programs and dual master’s and PhD programs are typically 5 years long. If you’re enrolling in an online, hybrid or accelerated PhD program, the timeline is usually 2-3 years, but there are some extremely short 1-year PhD programs offered online for specific disciplines.

Yes, you can finish your PhD before the “normal” timeline. For example, if you complete your coursework early, if you finish writing your thesis faster than average and get it approved, or if you otherwise complete all your PhD program requirements before the anticipated finish date. 

Yes, there are online PhDs available for certain fields and disciplines. These typically range from 2-3 years, although there are some traditional 4-year PhD programs offered online. There are also some “accelerated” online PhDs which last 12-18 months.

A PhD program is not necessarily shorter if you first complete a master’s degree, but having gone through a master’s program can better prepare you to finish your PhD faster. Some PhD programs accept credit hours from your master’s degree towards the coursework requirements for a PhD, and if you’ve previously written a master’s thesis or completed some research during your graduate studies, this will be an advantage. Since you’ll already be familiar with the process of writing a thesis and conducting your own research, you can avoid some stumbling blocks in your PhD program that might otherwise slow down your progress.

Yes, it is possible to get a PhD without first completing a master’s degree. There are direct entry PhD programs that allow students with a bachelor’s degree to enroll, so long as they meet the admission requirements and have exceptional academic records. Some online PhDs also waive the master’s degree requirement.

Yes, it is possible to complete a traditional PhD program in a shorter amount of time than anticipate. This usually means dedicating yourself to full-time study or taking on a larger course load and increased research hours. It takes significant work, but it can be done with the right schedule and commitment.

The fastest PhD programs are the short, 1-year accelerated programs. These programs have fewer credit hours to complete, and some have no dissertation requirement, only qualifying exams to finish. However, there are not many programs out there, and they are not available for every field of interest.
