7 steps to writing a dissertation

A dissertation is an extended piece of academic writing based on your own research. It gives you the opportunity to:

• develop your own perspective
• engage with existing scholarship
• investigate a topic in depth.

Whether you're studying at undergraduate, Masters or PhD level, the goal is the same: to demonstrate that you can plan, manage and complete an independent research project, and communicate your findings through a clear, well-supported argument.

1. Choose your topic

The topic you choose will shape your entire dissertation, so it's worth taking the time to get it right. Most students begin with a broad area of interest and gradually narrow their focus through:

• discussions with their supervisor
• ongoing research
• wider reading.

A good topic should be something you're genuinely interested in and able to explore in depth within the available time and word count. As Dr Steve Briggs, director of learning, teaching and libraries at the University of Bedfordshire, explains, 'a strong dissertation topic is focused, manageable and genuinely interesting to the student.'

Choosing a topic with your future goals in mind can help maintain motivation and build knowledge in a field you'd like to work in. Explore our what you can do with your degree guides or discover graduate job roles by sector to see where your studies could take you.

'It is completely normal for a student's argument or focus to evolve during the research process, as engaging with literature and evidence often leads to more refined and thoughtful ideas,' explains Dr Briggs.

If your project does begin to move in a different direction, there's no need to panic. However, if you're considering a significant change to your topic or research question, speak to your supervisor as early as possible.

Refining your focus isn't a setback - it's often a sign that you're engaging with the literature and developing a deeper understanding of the subject.

2. Understand expectations and plan your dissertation

Before you start researching, make sure you fully understand what's expected of you. Dissertation requirements vary between universities and courses, so clarifying expectations early can help you:

• meet key deadlines
• reduce the risk of mistakes
• save time.

You'll also need to check whether your course requires additional components, such as:

• a proposal
• an ethics application
• a reflective report.

If you're feeling overwhelmed, you're not alone. A dissertation is often the largest independent project you'll undertake at university, so it's natural to feel daunted by its scale.

The key is to avoid treating your dissertation as a single large task. Instead, Dr Briggs advises, 'breaking the dissertation into smaller stages and setting manageable goals can make the process feel much more achievable.'

These milestones might include:

• completing your proposal
• collecting and analysing data
• drafting chapters
• editing and proofreading
• finalising your submission.

Be sure to allow enough time for feedback, revisions and any unexpected delays - you'll thank yourself when submission day approaches.

3. Write your proposal and develop your thesis

If your course requires a dissertation proposal, this is your first opportunity to define your project clearly. A proposal typically outlines your:

• aims and objectives
• methodology
• rationale for investigating the topic
• research question.

Taking the time to establish the foundations at this stage will make the rest of the dissertation process much easier.

Alongside your proposal, you'll need to develop a clear thesis statement. This is the central argument that guides your research and writing. According to Dr Briggs, a good research question should be 'clear, specific and achievable within the available timeframe and word count.'

Remember, a dissertation is more than a summary of existing research. As Dr Briggs explains, 'a strong dissertation is focused, clearly structured and demonstrates critical thinking throughout.'

The best dissertations:

• analyse ideas rather than simply describing them
• engage critically with evidence
• present a coherent, well-supported argument.

It's also important to remain open to where your research may lead. You may come across evidence that challenges your initial assumptions or takes your work in an unexpected direction.

What matters is that you explain your reasoning clearly and use the evidence you've gathered to support your conclusions.

4. Choose your research methods and conduct research

This is the stage where you'll begin your literature review and decide how you'll gather evidence to answer your research question.

A literature review is more than a summary of existing research. Dr Briggs explains that 'students can move beyond description by comparing different perspectives, evaluating the strengths and weaknesses of existing research and explaining how it relates to their own research question.'

Rather than summarising sources individually, a strong literature review should:

• draw connections between different perspectives
• highlight key debates
• identify gaps in existing research.

Instead of focusing on the number of references you include, prioritise high-quality, relevant sources that:

• demonstrate engagement with the wider research
• support your argument.

Depending on your project, you may draw on secondary research sources such as:

• books
• journal articles
• reports.

Alternatively, you might collect your own primary data using methods such as:

• experiments
• interviews
• surveys.

If your research involves human participants or sensitive information, you may need to gain ethical approval before collecting data. This may include:

• completing an application
• following your university's requirements for storing and handling data securely
• obtaining informed consent.

If your data collection or experiments involve working in teams, explore our 3 tips for successful group work to help you:

• communicate effectively
• keep your project on track
• share responsibilities fairly.

Whatever approach you take, it should be appropriate for your research question and achievable within your timeframe.

Dr Briggs advises students to 'plan a dissertation with data analysis in mind' and to 'be clear from the start about what analysis will be used'. This will help you identify exactly what data you need to collect and avoid gaps later.

Using high-quality academic sources is essential. You can find relevant material through databases such as:

• Google Scholar
• JSTOR
• your university library.

5. Work with your supervisor

Your supervisor is there to guide and support you throughout the dissertation process. Staying in regular contact can help you:

• address challenges early
• keep your project moving forward
• stay focused.

See our tips on getting the most out of your contact hours at university.

How often you meet will depend on your course, but it's important to make the most of each opportunity to discuss your work. As Dr Briggs notes, 'the most productive meetings are focused and proactive, with students taking ownership of their progress and acting on feedback between sessions.'

To get the most out of your meetings:

• arrive prepared with specific questions
• bring draft sections or particular areas you'd like feedback on.

Keep a record of the feedback you receive and set aside time to act on it. While your supervisor can offer guidance, suggestions and academic expertise, you're ultimately responsible for:

• driving your project forward
• making decisions about your research
• managing your time effectively.

6. Write your dissertation

Once your research is underway, it's time to start writing. The time required for this stage will depend on your level of study.

• Undergraduate - typically completed over several months.
• Masters - often require more in-depth research and independent analysis.
• Doctoral - can take several years to complete.

Although requirements vary between subjects and institutions, most dissertations follow a broadly similar structure:

• an introduction
• a literature review
• methodology
• results and discussion
• a conclusion.

As you write, keep your research question in mind. Before adding a source, paragraph or section, ask yourself: 'Does this help answer my research question or strengthen my argument?'

Referencing is a crucial part of dissertation writing. Make sure you consistently follow your university's required referencing style and cite every source to avoid plagiarism.

Explore what skills employers want to understand how research, critical thinking and clear communication all contribute to your employability beyond your degree.

If you're working with multiple sources, reference management tools such as Mendeley or Zotero can help you:

• keep track of citations
• organise your research
• save time when formatting your bibliography.

You'll also need to include an abstract, which provides a concise overview of your dissertation, covering the:

• research question
• methodology
• key findings
• conclusions.

Although the abstract appears at the beginning of the dissertation, it's usually written last, so you can accurately summarise:

• what you did
• what you found
• why it matters.

As you write your dissertation, it can also help to think about how your research interests might shape your future career path. Explore our guide on choosing a career to start connecting your academic work with your:

• long-term goals beyond university
• strengths
• values.

7. Edit, proofread and submit

Once you've finished writing, give yourself time to step away from your dissertation before revisiting it. Creating some distance between your final draft and submission can make it much easier to spot:

• gaps in your evidence
• issues with structure and clarity
• weaknesses in your argument.

Avoid leaving editing until the last minute. As Dr Briggs explains, 'effective editing goes beyond grammar and spelling checks; it also involves reviewing the clarity of the argument, the structure of chapters, consistency in referencing and the overall flow of the dissertation.'

There are also simple techniques that can help you spot issues more easily, such as:

• asking someone else to read your work
• reading it aloud
• reviewing it in a different environment.

If possible, seek feedback from your supervisor or trusted peers before submitting. Being open to constructive criticism and making thoughtful revisions can significantly strengthen your final piece.

Before submission, carry out a final review to ensure you've met all course requirements. Check:

• your citations and references
• that each section is complete
• the formatting.

You should also confirm that you've included all required elements, such as a:

• contents page
• declaration form
• title page.

Most universities require dissertations to be submitted online, though some courses may still require a printed copy. Make sure you understand the submission process and avoid leaving your upload until the final minutes before the deadline.

As submission day approaches, try not to get caught up in endless minor edits. Dr Briggs advises focusing on progress rather than perfection: 'a well-planned, carefully revised dissertation is always stronger than work completed in a last-minute rush.'

Remember that it's completely normal to feel stressed or overwhelmed by deadlines. If you're finding this period challenging, explore our guide on 5 ways to manage student stress for practical tips to help you stay calm.
