- Universities and schools
What it does well
- Integrated into the assignment flow, so it is the score that actually decides your grade
- Reports a sentence-level highlight, not just a document percentage
Where it fails
- Students have no way to check their own work before submission — the biggest source of anxiety in this niche
- Turnitin's own documentation warns the score is an indicator, not proof, and should not be used alone for a misconduct case
- Documented weaker performance on short documents and on non-native English writing
