Overview
Turnitin is a comprehensive tool that helps maintain the originality of student work by comparing submissions against an extensive database of academic content, web pages, and student papers. The similarity reports generated by Turnitin highlight matching text and provide a similarity score, enabling faculty to quickly identify potential instances of plagiarism.

Understanding the Similarity Score
Turnitin does not check for plagiarism in writing. We do check all submissions against our database. If any text in a submission is similar to one of our sources, these matches are highlighted for you to review.
It is perfectly natural for a submission to match against some of our database. Our database includes billions of web pages: both current and archived content from the internet, a repository of works students have submitted to Turnitin in the past, and a collection of documents, which comprises thousands of periodicals, journals, and publications.
Even when a submission has quotation marks and references, the quoted text will show as a match. The similarity score is simply the percentage of text in a submission that matched to other sources. Use this as a tool within your review process to make your own determination if any academic misconduct is present.
Similarity score percentage ranges
The color of the report icon indicates the submission’s similarity score, based on the amount of matching text found. The percentage range is 0% to 100%. The colors for similarity ranges are:
Green: 0% matching text
Blue: 1-24% matching text
Yellow: 25-49% matching text
Orange: 50-74% matching text
Red: 75-100% matching text
