Turnitin and false positives

The dominant academic integrity platform. Its AI writing report gives a percentage of the document it believes was generated.

What it claims

Turnitin's own guidance acknowledges false positives are possible and notes that lower score ranges are less reliable. The company has repeatedly said the report should not be used as the sole basis for action against a student.

Where it fails

Works badly on highly structured, formulaic or heavily edited prose, which describes a great deal of legitimate academic writing. Non-native English writers have reported elevated flag rates.

How to respond

Request the full report and the institution's policy on its use. Quote the vendor's own guidance about sole reliance. Then submit process evidence to a human.

Worth knowing

Independent testing in 2026 found the leading detectors flagged almost no genuine human text, which is not the same as saying a particular institution will accept that.
