Higher education is filled with milestones. When completing your PhD , you will be required to complete a dissertation. Even if you’ve heard this word thrown around before, you still may be questioning “What is a dissertation?” It’s a common question, especially for those considering to join or are already in a graduate program. As such, here’s everything you need to know about dissertations.
What is a Dissertation?
A dissertation is a written document that details research. A dissertation also signifies the completion of your PhD program. It is required to earn a PhD degree, which stands for Doctor of Philosophy.
A PhD is created from knowledge acquired from:
1. Coursework:
A PhD program consists of academic courses that are usually small in size and challenging in content. Most PhD courses consist of a high amount and level of reading and writing per week. These courses will help prepare you for your dissertation as they will teach research methodology.
2. Research:
For your dissertation, it is likely that you will have the choice between performing your own research on a subject , or expanding on existing research. Likely, you will complete a mixture of the two. For those in the hard sciences, you will perform research in a lab. For those in humanities and social sciences, research may mean gathering data from surveys or existing research.
3. Analysis:
Once you have collected the data you need to prove your point, you will have to analyze and interpret the information. PhD programs will prepare you for how to conduct analysis, as well as for how to position your research into the existing body of work on the subject matter.
4. Support:
The process of writing and completing a dissertation is bigger than the work itself. It can lead to research positions within the university or outside companies. It may mean that you will teach and share your findings with current undergraduates, or even be published in academic journals. How far you plan to take your dissertation is your choice to make and will require the relevant effort to accomplish your goals.
Moving from Student to Scholar
In essence, a dissertation is what moves a doctoral student into becoming a scholar. Their research may be published, shared, and used as educational material moving forwards.
Thesis vs. Dissertation
Basic differences.
Grad students may conflate the differences between a thesis and a dissertation.
Simply put, a thesis is what you write to complete a master’s degree. It summarizes existing research and signifies that you understand the subject matter deeply.
On the other hand, a dissertation is the culmination of a doctoral program. It will likely require your own research and it can contribute an entirely new idea into your field.
Structural Differences
When it comes to the structure, a thesis and dissertation are also different. A thesis is like the research papers you complete during undergraduate studies. A thesis displays your ability to think critically and analyze information. It’s less based on research that you’ve completed yourself and more about interpreting and analyzing existing material. They are generally around 100 pages in length.
A dissertation is generally two to three times longer compared to a thesis. This is because the bulk of the information is garnered from research you’ve performed yourself. Also, if you are providing something new in your field, it means that existing information is lacking. That’s why you’ll have to provide a lot of data and research to back up your claims.
Your Guide: Structuring a Dissertation
Dissertation length.
The length of a dissertation varies between study level and country. At an undergraduate level, this is more likely referred to as a research paper, which is 10,000 to 12,000 words on average. At a master’s level, the word count may be 15,000 to 25,000, and it will likely be in the form of a thesis. For those completing their PhD, then the dissertation could be 50,000 words or more.

Format of the dissertation.
Here are the items you must include in a dissertation. While the format may slightly vary, here’s a look at one way to format your dissertation:
1. Title page:
This is the first page which includes: title, your name, department, degree program, institution, and submission date. Your program may specify exactly how and what they want you to include on the title page.
2. Acknowledgements:
This is optional, but it is where you can express your gratitude to those who have helped you complete your dissertation (professors, research partners, etc.).
3. Abstract:
The abstract is about 150-300 words and summarizes what your research is about. You state the main topic, the methods used, the main results, and your conclusion.
4. Table of Contents
Here, you list the chapter titles and pages to serve as a wayfinding tool for your readers.
5. List of Figures and Tables:
This is like the table of contents, but for graphs and figures.
6. List of Abbreviations:
If you’ve constantly abbreviated words in your content, define them in a list at the beginning.
7. Glossary:
In highly specialized work, it’s likely that you’ve used words that most people may not understand, so a glossary is where you define these terms.
8. Introduction:
Your introduction sets up the topic, purpose, and relevance. It’s where readers will understand what they expect to gain from your dissertation.
9. Literature Review / Theoretical Framework:
Based on the research you performed to create your own dissertation, you’ll want to summarize and address the gaps in what you researched.
10. Methodology
This is where you define how you conducted your research. It offers credibility for you as a source of information. You should give all the details as to how you’ve conducted your research, including: where and when research took place, how it was conducted, any obstacles you faced, and how you justified your findings.
11. Results:
This is where you share the results that have helped contribute to your findings.
12. Discussion:
In the discussion section, you explain what these findings mean to your research question. Were they in line with your expectations or did something jump out as surprising? You may also want to recommend ways to move forward in researching and addressing the subject matter.
13. Conclusion:
A conclusion ties it all together and summarizes the answer to the research question and leaves your reader clearly understanding your main argument.
14. Reference List:
This is the equivalent to a works cited or bibliography page, which documents all the sources you used to create your dissertation.
15. Appendices:
If you have any information that was ancillary to creating the dissertation, but doesn’t directly fit into its chapters, then you can add it in the appendix.
Drafting and Rewriting
As with any paper, especially one of this size and importance, the writing requires a process. It may begin with outlines and drafts, and even a few rewrites. It’s important to proofread your dissertation for both grammatical mistakes, but also to ensure it can be clearly understood.
It’s always useful to read your writing out loud to catch mistakes. Also, if you have people who you trust to read it over — like a peer, family member, mentor, or professor — it’s very helpful to get a second eye on your work.
How is it Different from an Essay?
There are a few main differences between a dissertation and an essay. For starters, an essay is relatively short in comparison to a dissertation, which includes your own body of research and work. Not only is an essay shorter, but you are also likely given the topic matter of an essay. When it comes to a dissertation, you have the freedom to construct your own argument, conduct your own research, and then prove your findings.
Types of Dissertations
You can choose what type of dissertation you complete. Often, this depends on the subject and doctoral degree, but the two main types are:
This relies on conducting your own research.
Non-empirical:
This relies on studying existing research to support your argument.

More things you should know.
A dissertation is certainly no easy feat. Here’s a few more things to remember before you get started writing your own:
1. Independent by Nature:
The process of completing a dissertation is self-directed, and therefore can feel overwhelming. However, if you approach it like the new experience that it is with an open-mind and willingness to learn, you will make it through!
2. Seek Support:
There are countless people around to offer support. From professors to peers, you can always ask for help throughout the process.
3. Writing Skills:
The process of writing a dissertation will further hone your writing skills which will follow you throughout your life. These skills are highly transferable on the job, from having the ability to communicate to also developing analytical and critical thinking skills.
4. Time Management:
You can work backwards from the culmination of your program to break down this gargantuan task into smaller pieces. That way, you can manage your time to chip away at the task throughout the length of the program.
5. Topic Flexibility:
It’s okay to change subject matters and rethink the point of your dissertation. Just try as much as possible to do this early in the process so you don’t waste too much time and energy.
The Wrap Up
A dissertation marks the completion of your doctoral program and moves you from being a student to being a scholar. While the process is long and requires a lot of effort and energy, you have the power to lend an entirely new research and findings into your field of expertise.
As always, when in the thick of things, remember why you started. Completing both your dissertation and PhD is a commendable accomplishment.
