## Question
Can Turnitin's AI score alone prove a student used ChatGPT?

## Short Answer
No. A Turnitin AI score can be a review signal, but Turnitin says it should not be the only basis for action against a student.

## Copy-Ready Reply
A Turnitin AI score alone is not proof. Turnitin's own guidance says the AI Writing score should not be used as the sole basis for adverse action. Please review drafts, notes, version history, and the actual writing before treating this as misconduct.

## Use Case
Paste this into an appeal, email, or comment reply.
Best for appeals, emails to instructors, parent replies, and comment threads where the exact wording matters.

## Practical Checks
- Treat the score as a lead, not a verdict.
- Ask for process evidence: drafts, notes, version history, citations, and oral explanation.
- If the accusation is high stakes, the burden should be stronger than one detector score.

## Proof Notes
1. Turnitin's public guide warns against using the AI Writing score as the sole basis for adverse action.
2. Shorter submissions and unusual writing patterns can make detector outputs less useful.
3. A clean appeal usually focuses on process evidence, not arguing that every detector is useless.
