How to Choose a Dissertation Topic | 8 Steps to Follow

Published on November 11, 2022 by Shona McCombes and Tegan George. Revised on November 20, 2023.

Choosing your dissertation topic is the first step in making sure your research goes as smoothly as possible. When choosing a topic, it’s important to consider:

• Your institution and department’s requirements
• Your areas of knowledge and interest
• The scientific, social, or practical relevance
• The availability of data and resources
• The timeframe of your dissertation
• The relevance of your topic

You can follow these steps to begin narrowing down your ideas.

Table of contents

Step 1: check the requirements, step 2: choose a broad field of research, step 3: look for books and articles, step 4: find a niche, step 5: consider the type of research, step 6: determine the relevance, step 7: make sure it’s plausible, step 8: get your topic approved, other interesting articles, frequently asked questions about dissertation topics.

The very first step is to check your program’s requirements. This determines the scope of what it is possible for you to research.

• Is there a minimum and maximum word count?
• When is the deadline?
• Should the research have an academic or a professional orientation?
• Are there any methodological conditions? Do you have to conduct fieldwork, or use specific types of sources?

Some programs have stricter requirements than others. You might be given nothing more than a word count and a deadline, or you might have a restricted list of topics and approaches to choose from. If in doubt about what is expected of you, always ask your supervisor or department coordinator.

Start by thinking about your areas of interest within the subject you’re studying. Examples of broad ideas include:

• Twentieth-century literature
• Economic history
• Health policy

To get a more specific sense of the current state of research on your potential topic, skim through a few recent issues of the top journals in your field. Be sure to check out their most-cited articles in particular. For inspiration, you can also search Google Scholar , subject-specific databases , and your university library’s resources.

As you read, note down any specific ideas that interest you and make a shortlist of possible topics. If you’ve written other papers, such as a 3rd-year paper or a conference paper, consider how those topics can be broadened into a dissertation.

After doing some initial reading, it’s time to start narrowing down options for your potential topic. This can be a gradual process, and should get more and more specific as you go. For example, from the ideas above, you might narrow it down like this:

• Twentieth-century literature   Twentieth-century Irish literature   Post-war Irish poetry
• Economic history   European economic history   German labor union history
• Health policy   Reproductive health policy   Reproductive rights in South America

All of these topics are still broad enough that you’ll find a huge amount of books and articles about them. Try to find a specific niche where you can make your mark, such as: something not many people have researched yet, a question that’s still being debated, or a very current practical issue.

At this stage, make sure you have a few backup ideas — there’s still time to change your focus. If your topic doesn’t make it through the next few steps, you can try a different one. Later, you will narrow your focus down even more in your problem statement and research questions .

There are many different types of research , so at this stage, it’s a good idea to start thinking about what kind of approach you’ll take to your topic. Will you mainly focus on:

• Collecting original data (e.g., experimental or field research)?
• Analyzing existing data (e.g., national statistics, public records, or archives)?
• Interpreting cultural objects (e.g., novels, films, or paintings)?
• Comparing scholarly approaches (e.g., theories, methods, or interpretations)?

Many dissertations will combine more than one of these. Sometimes the type of research is obvious: if your topic is post-war Irish poetry, you will probably mainly be interpreting poems. But in other cases, there are several possible approaches. If your topic is reproductive rights in South America, you could analyze public policy documents and media coverage, or you could gather original data through interviews and surveys .

You don’t have to finalize your research design and methods yet, but the type of research will influence which aspects of the topic it’s possible to address, so it’s wise to consider this as you narrow down your ideas.

It’s important that your topic is interesting to you, but you’ll also have to make sure it’s academically, socially or practically relevant to your field.

• Academic relevance means that the research can fill a gap in knowledge or contribute to a scholarly debate in your field.
• Social relevance means that the research can advance our understanding of society and inform social change.
• Practical relevance means that the research can be applied to solve concrete problems or improve real-life processes.

The easiest way to make sure your research is relevant is to choose a topic that is clearly connected to current issues or debates, either in society at large or in your academic discipline. The relevance must be clearly stated when you define your research problem .

Before you make a final decision on your topic, consider again the length of your dissertation, the timeframe in which you have to complete it, and the practicalities of conducting the research.

Will you have enough time to read all the most important academic literature on this topic? If there’s too much information to tackle, consider narrowing your focus even more.

Will you be able to find enough sources or gather enough data to fulfil the requirements of the dissertation? If you think you might struggle to find information, consider broadening or shifting your focus.

Do you have to go to a specific location to gather data on the topic? Make sure that you have enough funding and practical access.

Last but not least, will the topic hold your interest for the length of the research process? To stay motivated, it’s important to choose something you’re enthusiastic about!

Most programmes will require you to submit a brief description of your topic, called a research prospectus or proposal .

Remember, if you discover that your topic is not as strong as you thought it was, it’s usually acceptable to change your mind and switch focus early in the dissertation process. Just make sure you have enough time to start on a new topic, and always check with your supervisor or department.

If you want to know more about the research process , methodology , research bias , or statistics , make sure to check out some of our other articles with explanations and examples.

Methodology

• Sampling methods
• Simple random sampling
• Stratified sampling
• Cluster sampling
• Likert scales
• Reproducibility

 Statistics

• Null hypothesis
• Statistical power
• Probability distribution
• Effect size
• Poisson distribution

Research bias

• Optimism bias
• Cognitive bias
• Implicit bias
• Hawthorne effect
• Anchoring bias
• Explicit bias

Formulating a main research question can be a difficult task. Overall, your question should contribute to solving the problem that you have defined in your problem statement .

However, it should also fulfill criteria in three main areas:

• Researchability
• Feasibility and specificity
• Relevance and originality

All research questions should be:

• Focused on a single problem or issue
• Researchable using primary and/or secondary sources
• Feasible to answer within the timeframe and practical constraints
• Specific enough to answer thoroughly
• Complex enough to develop the answer over the space of a paper or thesis
• Relevant to your field of study and/or society more broadly

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence?

A dissertation prospectus or proposal describes what or who you plan to research for your dissertation. It delves into why, when, where, and how you will do your research, as well as helps you choose a type of research to pursue. You should also determine whether you plan to pursue qualitative or quantitative methods and what your research design will look like.

It should outline all of the decisions you have taken about your project, from your dissertation topic to your hypotheses and research objectives , ready to be approved by your supervisor or committee.

Note that some departments require a defense component, where you present your prospectus to your committee orally.

The best way to remember the difference between a research plan and a research proposal is that they have fundamentally different audiences. A research plan helps you, the researcher, organize your thoughts. On the other hand, a dissertation proposal or research proposal aims to convince others (e.g., a supervisor, a funding body, or a dissertation committee) that your research topic is relevant and worthy of being conducted.

How To Choose A Research Topic

Step-By-Step Tutorial With Examples + Free Topic Evaluator

By: Derek Jansen (MBA) | Expert Reviewer: Dr Eunice Rautenbach | April 2024

Choosing the right research topic is likely the  most important decision you’ll make on your dissertation or thesis journey. To make the right choice, you need to take a systematic approach and evaluate each of your candidate ideas across a consistent set of criteria. In this tutorial, we’ll unpack five essential criteria that will help you evaluate your prospective research ideas and choose a winner.

Overview: The “Big 5” Key Criteria

• Topic originality or novelty
• Value and significance
• Access to data and equipment
• Time limitations and implications
• Ethical requirements and constraints

Criterion #1: Originality & Novelty

As we’ve discussed extensively on this blog, originality in a research topic is essential. In other words, you need a clear research gap . The uniqueness of your topic determines its contribution to the field and its potential to stand out in the academic community. So, for each of your prospective topics, ask yourself the following questions:

• What research gap and research problem am I filling?
• Does my topic offer new insights?
• Am I combining existing ideas in a unique way?
• Am I taking a unique methodological approach?

To objectively evaluate the originality of each of your topic candidates, rate them on these aspects. This process will not only help in choosing a topic that stands out, but also one that can capture the interest of your audience and possibly contribute significantly to the field of study – which brings us to our next criterion.

Criterion #2: Value & Significance

Next, you’ll need to assess the value and significance of each prospective topic. To do this, you’ll need to ask some hard questions.

• Why is it important to explore these research questions?
• Who stands to benefit from this study?
• How will they benefit, specifically?

By clearly understanding and outlining the significance of each potential topic, you’ll not only be justifying your final choice – you’ll essentially be laying the groundwork for a persuasive research proposal , which is equally important.

Criterion #3: Access to Data & Equipment

Naturally, access to relevant data and equipment is crucial for the success of your research project. So, for each of your prospective topic ideas, you’ll need to evaluate whether you have the necessary resources to collect data and conduct your study.

Here are some questions to ask for each potential topic:

• Will I be able to access the sample of interest (e.g., people, animals, etc.)?
• Do I have (or can I get) access to the required equipment, at the time that I need it?
• Are there costs associated with any of this? If so, what are they?

Keep in mind that getting access to certain types of data may also require special permissions and legalities, especially if your topic involves vulnerable groups (patients, youths, etc.). You may also need to adhere to specific data protection laws, depending on the country. So, be sure to evaluate these aspects thoroughly for each topic. Overlooking any of these can lead to significant complications down the line.

Criterion #4: Time Requirements & Implications

Naturally, having a realistic timeline for each potential research idea is crucial. So, consider the scope of each potential topic and estimate how long each phase of the research will take — from literature review to data collection and analysis, to writing and revisions. Underestimating the time needed for a research project is extremely common , so it’s important to include buffer time for unforeseen delays.

Remember, efficient time management is not just about the duration but also about the timing . For example, if your research involves fieldwork, there may specific times of the year when this is most doable (or not doable at all).  So, be sure to consider both time and timing for each of your prospective topics.

Criterion #5: Ethical Compliance

Failing to adhere to your university’s research ethics policy is a surefire way to get your proposal rejected . So, you’ll need to evaluate each topic for potential ethical issues, especially if your research involves human subjects, sensitive data, or has any potential environmental impact.

Remember that ethical compliance is not just a formality – it’s a responsibility to ensure the integrity and social responsibility of your research. Topics that pose significant ethical challenges are typically the first to be rejected, so you need to take this seriously. It’s also useful to keep in mind that some topics are more “ethically sensitive” than others , which usually means that they’ll require multiple levels of approval. Ideally, you want to avoid this additional admin, so mark down any prospective topics that fall into an ethical “grey zone”.

If you’re unsure about the details of your university’s ethics policy, ask for a copy or speak directly to your course coordinator. Don’t make any assumptions when it comes to research ethics!

Key Takeaways

In this post, we’ve explored how to choose a research topic using a systematic approach. To recap, the “Big 5” assessment criteria include:

• Topic originality and novelty
• Time requirements
• Ethical compliance

Choosing a dissertation topic is really difficult.

When I had to choose dissertation topic I agonized for weeks.

And I’ve supervised over 50 students’ dissertations across undergraduate, masters and PhD levels. All of my students agonized over their topics, too.

So you’re not alone in your struggle.

The below tips for choosing a dissertation topic are the ones I wish I was given when I was in the process of looking for a suitable topic.

If only I’d known these points, I would have saved a lot of time and stress for myself. So if these tips only help one person out, I’ll be happy.

These tips really work for just about anybody. They’re particularly useful for undergraduate and Masters level students who are writing dissertations. But, I’m sure most doctoral students will also find these points relevant, too. Especially tips 1 – 3.

Here are my tips on how to choose a dissertation topic – I hope they come in handy, and good luck on your research journey!

1. It Doesn’t have to be Unique (Yet).

This is the one piece of advice I wish I had gotten when I was choosing my dissertation topic.

Many students feel like they need to find a unique topic that will blow their markers away.

I was this student.

I thought that I had to choose a topic and idea that was going to make a unique contribution to knowledge. I thought I had to discover something, or, at the very least, choose a topic that no one has ever done before.

So here’s what I wish someone had told me:

It doesn’t matter if other people have done the same topic as you.

Don’t even let it phase you for a moment if someone else has chosen your topic. Just choose whatever topic you want.

Well, because your unique contribution doesn’t come at the start. It comes at the end!

You’ll find a way to make a unique contribution after you have completed your literature review . There is always time and space to find a new angle or different way of doing the topic than other people.

So, don’t choose your topic because it’s unique or different.

Then … how should you choose your topic? Points 2 and 3 give you some tips…

2. Make it Relevant to your Career Goals.

The first thing I recommend to all my students is to consider how their topic can help progress their careers.

When giving guidance to my students, I ask them these three questions:

• a) What sort of specialization do you want in your career? If you’re studying teaching, your questions might be: do you want to be a specialized literacy teacher? do you want to be an expert on behavior management? Do you want to be specialized in play-based learning ?
• b) How do you want to differentiate yourself from your competition? Your dissertation topic is going to be the topic you ‘sell’ as your area of expertise in future job interviews. If you want to get a great job, choose a topic that really stands out in the marketplace. Have a think right now for yourself: what areas of your industry are booming? For example, would it be better to specialize in coal or solar panels? Which one would be best to talk about in a job interview in the 21 st Century?
• c) Do you want to be a research pro? Most of my students don’t want to be researchers as a career. They do their dissertations to prove mastery of their topic – that’s all. The research is a means to an end. But, if you think you want to go on to do the next level degree (a PhD one day?) then you’ll want to focus on having a high quality methodology, not just an interesting topic.

So, have a think now: is there a topic that will help you get to where you plan on going? What expert knowledge do you want to be able to ‘sell’ in a future interview?

3. Ensure it’s Interesting to You.

You’re going to be wedded to your chosen for a long time. And by the end of this journey you’re going to hate it.

To make your life easier, choose a topic you’re interested in.

Here’s two ways of approaching this:

Choose a Topic you Think About a Lot.

Choose a dissertation topic that you find yourself talking about, complaining about or raving about to your parents. Choose something that makes you angry, inspired or intrigued.

For the next week or so, I recommend taking notes whenever you find yourself thinking idly about something. Is that something you’ve thought about a lot?

Or, Choose a Topic by Looking over Past Assessment Tasks.

Another way of approaching the search for an interesting topic is to look over past assignments.

What assessment task have you done in the past few years that gripped you? Which one did you enjoy the most when you were studying it?

Zoom in on that topic and see if you can turn it into a dissertation.

Bonus tip: If you found a topic that was based on a previous assessment task, see if you can convince the person who taught that subject to be your dissertation supervisor.

4. Keep it Simple.

Too often, students want to choose a topic that is complex and complicated. They come up with a long, detailed research question (usually with the help of their professor) that, really, is hard to understand!

The best strategy is to come up with a topic that is really, really straightforward. At least, the topic should start as simple and straightforward.

Your topic is going to grow and expand into a monster. It’ll be hard to tame and control. You’ll be following random tangents down rabbit holes that end up being dead-ends. You’ll research aspects of the topic and realize it was a completely pointless exercise.

The way to minimize the crazy growth of your research project is to simplify it right from the start. Make it a really simple idea.

For example, I had a student who wanted to research:

“How big is the gap in mathematics outcomes between children from middle-class and working-class backgrounds by age 16?”

I would think that this topic may be achievable by a top academic with a sizeable research grant, but my student was completing a 10,000 word dissertation for graduating her Bachelor of Arts with Honours.

After several agonizing research meetings, we peeled it back over and again until we ended up with something much simpler and more specific:

“What are teachers’ opinions of the impact of poverty on learning?”

Why is this simpler and more specific?

Well, with the second study, my student has a clear focus group (teachers) and an achievable methodology (interviews). This will be far simpler than somehow conducting tests on 16-year old children, getting a significant amount of children to participate in the study, and then dissecting their mathematics test results by income level.

Instead, we aimed small and simple to ensure the task itself was achievable.

We’re not here to win a Nobel prize. You can do that with your multi-million-dollar post-doctoral research grant. Get your degree first.

5. Ensure it’s Achievable.

This piece of advice builds on the previous advice, to “keep it simple”.

Keeping it simple means making sure you have a clear, small-scale focus.

Esuring the project is achievable means choosing a methodology that won’t break you.

Small Scale Qualitative Studies are Achievable for Anyone

I always suggest to my Undergraduate and Masters level students to aim for a small scale study with no more than 20 research participants.

Now, I know there will be many of you out there who want to do quantitative research studies. And in reality, you can do a quantitative study with a small group of students. These usually involve quantitative action research case studies.

If you’re set on a quantitative study, that’s fine. But find a supervisor with the right experience.

Personally, I usually recommend a qualitative focus group analysis for anyone doing their first dissertation.

The biggest mistake you can make is biting off more than you can chew.

Small scale qualitative studies are the easiest option . They can be achieved within your time frame. And you can certainly still get a very high grade.

So, let’s take the example of the previous research question, which we changed from:

For the first study, you will have to develop skills in quantitative data analysis , find a sizeable cohort of students, get permission from their parents, get special permission to study children you’re your university ethics committee, develop a quality testing mechanism, pilot the test, conduct the test, analyze the data, then interpret it.

For the second study, you will not have to develop complex mathematical skills, bother with getting permission to research children, or deal with the rigor of quantitative analysis.

In other words, you will be able to bypass many hurdles you may face.

That’s the benefit of a small-scale qualitative study. It’s a nice easy first dissertation methodology. You can do it and do it well.

I know my position is controversial, but hey … I’m here to tell you how to avoid problems, not to stand on a soapbox.

Consider Textual Analysis, Semiotic Analysis or Secondary Research

Finding people to interview, survey or participate in your study in any way at all can be intimidating.

I find it interesting and really fulfilling. But I understand if you think it’s too much for you at this point in time.

If you don’t want to have to go out and find research participants for your study, I recommend one of these types of study:

• Textual Analysis : you can look at policy documents or newspaper articles and analyze their ideological positioning , for example;
• Semiotic Analysis : The quintessential semiotic analysis is the analysis of advertising images or movies and the examination of the ways they depict people of different races, social classes or genders;
• Secondary Research: Look over other people’s research and try to identify themes across a range of research studies.

Now, these three different methodologies are far outside of the scope of this discussion, but consult with your dissertation supervisor if you’re overwhelmed by the idea of conducting research with real human beings. One of these three methodologies may help you bypass that process, and make the dissertation feel more achievable for you.

6. Search Online for Inspiration

If you’re still struggling to choose a dissertation topic,  go online to get inspiration!

There’s a few ways you can do this. Here’s a few good ones:

a) Google Previous Dissertation Topics

Many universities upload their students’ dissertations onto an online repository. This means there are a ton of open, free to access databases of previous students’ dissertations all over the internet.

Simply google “Dissertation” + “pdf” + a topic you’re interested in. If you’re a masters student, you can do “masters dissertation” + “pdf” + the topic; and if you’re an undegrad, then simply do “undergraduate dissertation” + “pdf” + the topic;. Simple!

Up will pop a ton of dissertations that you can instantly download to check out previous students’ successful dissertation topics.

Another benefit of doing this is that you’ll be able to view and model the structure that previous students have used as well. This can be super beneficial for you early on!

b) Look at Recent Articles Published in Journals focused on your Topic

If you scroll through the recent issues of journals in your topic, you’ll find a range of research topic ideas.

To get access to top journals in your topic, simply google “Scholarly Journal” + your topic. For example, I am a professor in education. So I’d google “Scholarly journal” + “Education”.

The homepages for a ton of journals will pop up in the Google search. Quickly scan through the recent issues of those journals to see if any ideas will pop up that interest you!

c) If you’re Studying Education or Teaching, Check Here

Lastly, a quick plug for another post I’ve written for dissertation students:

• 51+ Dissertation Ideas for Education students .

Go check that out if you want to write a dissertation on the ‘education’ topic.

7. Trust your Dissertation Supervisor

Your dissertation supervisor will have walked many students just like you through the research process before.

Look, I know many dissertation supervisors can be disappointingly aloof and disconnected from your research. And relationships can get very frosty with your supervisors indeed.

Trust your supervisor. They make recommendations for a reason. They know how to navigate the dissertation writing process. If your supervisor makes a recommendation, strong – very strongly – consider it.

Your supervisor also has expertise in one area of research or another. Take advantage of their expertise. Be flexible and let them sway you down certain paths. You need a knowledgeable partner in the research process.

So, trust your supervisor. You need their expertise more than you know.

8. Come up with 3-5 Ideas and Bring them to your Supervisor for Feedback

Your initial dissertation topic ideas will probably need a lot of refinement.

The person who will help you to refine your topic will be your dissertation supervisor. Their main job, unfortunately, is to curb your enthusiasm. It’s to show you what problems you’ll face if you follow certain paths and recommend alterations to ensure your topic is achievable.

So, approach your supervisor with your 3-5 top ideas and watch them do their magic. They should advise you on how to turn your ideas into reality.

Your ideas can be specific or broad – really, it doesn’t matter because you’ll walk out of your supervision meeting with a lot of changed ideas. It doesn’t need to be set in stone.

You could, for example, go up to your supervisor and say something like:

• “I’m interested in Erikson’s theory of development. Do you have any suggestions of how I can use Erikson’s ideas for a dissertation?”
• “I’m really into conservative politics. What ideas do you have for an achievable topic?”
• Any other ideas…

They’ll help you shape and mold your topic into something achievable.

9. Lastly, Stick to your Choice

When I did my dissertation, I questioned my topic daily: I’d always be thinking up new, better ideas for my dissertation!

But once you’re locked in, it’s hard to change your mind. You’re going to get ethics permission to conduct your study, not anyone else’s!

So, my advice is simple:

Once you’ve chosen your topic, commit.

If you’re desperate to do another topic, fine, do another degree. If you’re doing your Master’s right now, bank those other ideas for a potential PhD down the track.

But once you’ve made your choice, really … you’ve got to commit, block out all your regrets and dig in.

Don’t worry about your friends who chose a dissertation topic that is better than yours. Stay in your lane, be content with your topic, and create a great product.

Writing a dissertation is an exercise in being practical more than anything. That start from the very first choice: choosing a dissertation topic that’s achievable and good for your career, and will also put you on the path for top marks.
