What does a 30% Turnitin similarity score mean for my paper?

A 30% Turnitin similarity score means that nearly a third of your paper contains text matching existing sources in the database, but it does not automatically imply plagiarism. For law students, this high percentage often reflects standard legal citations, statutory phrasing, and common case names that the software flags as matches. To lower your score effectively, your best move is to filter the Turnitin report settings to exclude bibliography, citations, and small matches under five words. Because legal writing relies heavily on precise, unalterable terminology like "beyond a reasonable doubt" or specific bluebook citations, these elements inflate your score without actually indicating any academic dishonesty. For instance, a student writing a brief might find that simply citing the same landmark Supreme Court case multiple times across fifteen pages flags dozens of identical strings of text. By adjusting the filters, you can see your true similarity index and identify if you actually need to paraphrase any remaining blocks of text. Keep in mind that every professor interprets these reports differently, and institutional policies on acceptable thresholds vary. If your score remains high after filtering, you should proactively share the flagged report with your legal writing professor to explain the matches and ask for their specific guidance.
