Short answer
Can Turnitin's AI score alone prove a student used ChatGPT?
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.
What to say
Keep the claim narrow.
Turnitin's public guide warns against using the AI Writing score as the sole basis for adverse action.
Shorter submissions and unusual writing patterns can make detector outputs less useful.
A clean appeal usually focuses on process evidence, not arguing that every detector is useless.
