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:
Blue: No matching text
Green: One word to 24% matching text
Yellow: 25-49% matching text
Orange: 50-74% matching text
Red: 75-100% matching text
What search repositories are available?
- Internet: An active archive of 90+ billion current and archived web pages.
- Publications: A collection of over 80 million articles from library databases, textbook publishers, digital reference collections, subscription-based publications, homework helper sites, and books.
- Crossref: A collection of published scholarly works.
- Crossref Posted Content: A collection of scholarly works that have been submitted but not yet been published.
