What Do 15%, 25% and 40% Similarity Scores Mean?

Students often worry when a thesis or dissertation report shows 15%, 25% or 40% similarity. Such percentages describe how much text matches material available to the checking system, rather than establishing whether academic misconduct occurred.

A similarity score is not a plagiarism verdict

Even a 15% score may conceal an important unattributed passage. A 25% score might include correctly cited quotations and common academic language. A 40% score may warrant closer inspection, but does not automatically establish plagiarism. No single percentage threshold applies to every university.

How should 15%, 25% and 40% be interpreted?

Look beyond the headline figure: review matching passages, source links, quotation marks, citations, bibliography entries and filtering settings. DissLink allows you to examine similarity and AI-related indicators so you can identify sections needing review before submitting academic work.
