Similarity Score to AI Score

Educators are strongly cautioned in their use of this score. Many issues are addressed in Turnitin's AI Writing Detection Capabilities - FAQs. Some things to consider:

  • Turnitin uses a proprietary model, unavailable to the public, to analyze small, overlapping samples of written submissions and estimate the likelihood that portions of the writing were generated by AI
  • The overall “AI score” represents the average of all scores generated by the process of analyzing the small samples rather than a percentage of AI generated vs. content written by a human
  • While students can see Turnitin's Similarity score, they cannot see the AI score
  • Turnitin notes that "Our AI writing detection model may not always be accurate (it may misidentify both human and AI-generated text) so it should not be used as the sole basis for adverse actions against a student. It takes further scrutiny and human judgment in conjunction with an organization's application of its specific academic policies to determine whether any academic misconduct has occurred."
  • Students should be involved in conversations in your course around appropriate usage of generative AI technology
