Dissertation Plagiarism Check: How to Use Turnitin Correctly

Running a dissertation plagiarism check before submitting your work is one of the most important steps in final preparation. A dissertation plagiarism check through Turnitin or your institution's plagiarism detection software allows you to identify passages that may be incorrectly cited, insufficiently paraphrased, or inadvertently reproduced from other sources — giving you the opportunity to address them before submission rather than after.

Why You Should Run a Dissertation Plagiarism Check

A dissertation plagiarism check is a quality control tool, not just an institutional compliance step. Most students who submit work with plagiarism issues did not intend to plagiarise. Problems typically arise from poor note-taking practices that blur the boundary between your own words and a source's words, from misunderstanding what requires citation, or from paraphrasing that stays too close to original wording. A thorough dissertation plagiarism check catches these problems before submission when you still have time to fix them.

How Turnitin Works

Turnitin compares your dissertation against a vast database of academic papers, books, websites, and previously submitted student papers. When it finds matching text, it flags the passage and calculates a similarity score — the percentage of your text that matches other sources.

Your dissertation plagiarism check produces an originality report showing every flagged passage, identifying the matching source, and providing the overall similarity score. It is important to understand that the similarity score is not a plagiarism score. A high similarity score does not automatically mean plagiarism. A low score does not guarantee your dissertation is plagiarism-free. The score is a starting point for a qualitative assessment, not a verdict.

Interpreting Your Dissertation Plagiarism Check Results

When you receive your results, focus on individual flagged passages rather than the overall score. Some matches are entirely expected and unproblematic. Your reference list will match extensively with database sources — this is not plagiarism. Correctly quoted and cited passages will match their sources — this is the correct use of quotation. Commonly used phrases and standard academic formulations may also generate matches without being problematic.

The matches to examine carefully in your dissertation plagiarism check are those in the body of your text that are not in quotation marks and not directly following a citation. For each such passage, ask: Is this my own original phrasing? Is this a paraphrase of a cited source that needs rewording? Did I forget to add a citation? Is this text directly copied from a source?

What Similarity Score Is Acceptable

There is no universal acceptable similarity score. Different institutions set different thresholds, and the appropriate level varies by discipline and dissertation structure. As a general guide, scores below 15 percent are typically considered acceptable, with the understanding that much of the matched content will be correctly cited quotations and reference list entries.

Do not aim simply to reduce your dissertation plagiarism check score below a threshold. Aim to ensure every passage is either your own original prose, a correctly quoted and cited passage, or a genuine paraphrase with appropriate attribution. If you achieve this, your similarity score will reflect it.

Addressing Issues Found

Work through the originality report passage by passage. For each problematic passage, determine the appropriate resolution: add quotation marks and a citation, rewrite as a genuine paraphrase with a citation, or remove the passage entirely. After making revisions, run your dissertation plagiarism check again to confirm that all issues have been resolved. Allow enough time before your submission deadline to conduct your check, review results, revise, and check again.

Practical Tips for Stronger Dissertation Plagiarism Check Work

Strong dissertation plagiarism check work is built through deliberate practice and consistent attention to academic standards. The students who earn the highest grades are rarely the most naturally gifted — they are the most methodical, the most willing to seek and act on expert feedback, and the most committed to revising their work until it genuinely meets the standard required.

Begin every stage of your dissertation plagiarism check work with a clear understanding of what examiners are looking for at your academic level. Seek feedback early and act on it completely. Revise with specific criteria in mind rather than editing vaguely. And treat every piece of guidance you receive — from your supervisor, from model work, or from professional academic writing support — as an opportunity to understand the standard more deeply and to close the gap between your current work and that standard.

When to Run Your Dissertation Plagiarism Check

Timing matters when it comes to your dissertation plagiarism check. Running your dissertation plagiarism check too early — before your final editing and revision pass — means you will need to run it again after making changes, since editing your text can change what gets flagged. Running it too late — the night before submission — leaves no time to address issues the check reveals.

The optimal timing for your dissertation plagiarism check is after you have completed all substantive editing and revision but while you still have enough time before your submission deadline to review the results carefully, make any necessary corrections, and run the check a second time to confirm those corrections have resolved the flagged issues.

For most students, this means running the first dissertation plagiarism check approximately five to seven days before the submission deadline. This gives three to four days to review results and make corrections, and a further day or two to run the check again and save the final submission file with confidence.

Make the final run of your dissertation plagiarism check the very last substantive action before saving your submission file. Any editing you do after the final check — even correcting a single typo — should be checked to ensure it has not introduced any new issues.
