For many postgraduate students, earning a merit is a significant academic accomplishment. However, some students narrowly miss a distinction and wonder what prevented them from achieving the highest classification. Often, the difference is not a lack of effort or research. Instead, it lies in how effectively the dissertation demonstrates critical thinking, originality, methodological rigour, and academic judgement.

While grading criteria vary across universities and programmes, distinction-level dissertations consistently exceed expectations rather than simply meeting them. They present stronger arguments, deeper analysis, and a clearer contribution to the research topic.
In this guide, we'll explore the differences between merit and distinction dissertations, explain what examiners typically assess, and share practical strategies to help you strengthen your work before submission.
At many universities, particularly for master's programmes, dissertations contribute significantly to the final degree classification.
Although exact grade boundaries differ between institutions, a general guide is:
Classification | Typical Percentage* |
|---|---|
Pass | 50–59% |
Merit | 60–69% |
Distinction | 70%+ |
*Always check your university's official marking regulations, as classifications and thresholds may vary.
The difference between a merit and a distinction often reflects the overall quality and consistency of the dissertation rather than one outstanding chapter.
Dissertation examiners commonly evaluate:
Research quality
Critical analysis
Originality
Literature review
Research methodology
Data analysis
Discussion of findings
Academic writing
Organisation and structure
Referencing accuracy
Evidence-based conclusions
Strong performance across all these areas is usually necessary for distinction-level work.
Explains academic literature clearly.
Discusses relevant theories.
Demonstrates sound understanding.
Critically evaluates evidence.
Compares competing viewpoints.
Identifies strengths and weaknesses.
Synthesises multiple sources.
Demonstrates independent academic judgement.
Critical analysis is often one of the biggest factors separating merit from distinction.
Shows a good understanding of existing research.
Builds on previous research by:
Identifying knowledge gaps
Offering fresh interpretations
Connecting theories creatively
Developing insightful conclusions
Originality often comes from thoughtful interpretation rather than discovering entirely new knowledge.
Summarises relevant academic studies.
Evaluates:
Research quality
Methodological differences
Conflicting evidence
Knowledge gaps
Practical implications
The literature review becomes an analytical discussion rather than a collection of summaries.
Merit dissertations explain what methods were used.
Distinction dissertations also explain why those methods were appropriate.
For example:
Why qualitative rather than quantitative research?
Why this sampling strategy?
Why these analytical techniques?
Methodological justification demonstrates deeper research understanding.
The discussion chapter often determines whether a dissertation remains at merit level or progresses to distinction.
Explains findings.
Interprets findings by:
Comparing results with previous research
Explaining practical implications
Discussing unexpected findings
Evaluating limitations
Suggesting future research
Merit-level writing is generally clear and accurate.
Distinction-level writing is:
Concise
Persuasive
Well structured
Logically organised
Academically sophisticated
Strong writing supports stronger arguments.
One excellent chapter cannot compensate for weaknesses elsewhere.
Distinction dissertations maintain consistently high quality across:
Introduction
Literature review
Methodology
Results
Discussion
Conclusion
Every chapter contributes meaningfully to answering the research question.
Merit Dissertation | Distinction Dissertation |
|---|---|
Meets assessment criteria | Consistently exceeds expectations |
Good understanding of literature | Critical evaluation and synthesis |
Sound methodology | Fully justified methodology |
Clear discussion | Insightful interpretation |
Well organised | Exceptionally coherent |
Good academic writing | Polished and persuasive writing |
Relevant conclusions | Original, evidence-based conclusions |
Many dissertations receive a merit because they:
Rely too heavily on descriptive writing
Lack sufficient critical evaluation
Fail to justify methodological decisions
Repeat evidence instead of synthesising it
Present weak discussions
Ignore research limitations
Leave proofreading until the final day
Addressing these issues can significantly strengthen dissertation quality.
Evaluate evidence instead of simply describing previous research.
Ensure each chapter contributes directly to answering the research question.
Explain why you selected:
Research methods
Theoretical frameworks
Data collection techniques
Analytical approaches
Regularly compare your dissertation against the university's marking criteria.
Your conclusion should:
Answer the research question directly
Highlight contributions
Discuss limitations
Recommend future research
Final proofreading should check:
Grammar
Spelling
Formatting
Referencing
Consistency
Headings
Tables and figures
Constructive feedback often identifies improvements that students overlook after months of working on the same project.
Useful feedback can reveal:
Weak arguments
Structural inconsistencies
Repetitive writing
Referencing issues
Opportunities for deeper critical analysis
Addressing recurring feedback first usually produces the greatest improvement.
Many universities permit students to receive guidance on:
Academic writing
Grammar
Referencing
Formatting
Structure
Proofreading
Students remain responsible for all original research, analysis, interpretation, and conclusions. Any assistance should comply with institutional academic integrity policies.
The difference between a merit and a distinction dissertation is rarely determined by word count or formatting alone. More often, it reflects the quality of your critical analysis, originality, research design, and ability to develop well-supported academic arguments.
By strengthening analytical depth, justifying methodological choices, improving chapter coherence, and aligning your work with the official marking rubric, you can significantly enhance your dissertation before submission.
A distinction is usually achieved through consistent excellence across every chapter—not perfection in just one section.
