Similarity scoring scenarios from Turnitin
A high similarity score does not always suggest that a piece of writing has been plagiarized, just as a low similarity score does not always indicate that no plagiarism has occurred. Consider the following scenarios:
- Submitting a document of considerable size could result in a 0% similarity score with a report that still contains matches. This is because the similarity score has been rounded to 0%, rather than being exactly 0%.
- You may have submitted multiple drafts of the same paper to your institution's private repository, meaning your final draft has resulted in a score of 100%. To avoid this issue, we advise that you only submit your final draft to the private repository.
- An individual within your institution has managed to acquire a copy of your document. They submit this document to the institution's private repository and receive a similarity score of 25%. You submit your original document a week later to the private repository but receive a 100% similarity score.

Turnitin checks a user's work against its extensive database. If instances are found where a user's writing is similar to or matches against a source this will be flagged for your review in the match overview.
The 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 public scholarly publications, which comprises thousands of periodicals, journals, and publications.
