Turnitin AI writing detection

Vanderbilt disabled Turnitin's AI detector after months of use and testing

StoppedCompany's own claimOfficial ↗

Problem

The detector was intended to identify student writing produced by tools such as ChatGPT. It became available to Vanderbilt instructors through their existing Turnitin workflow in April 2023.

Approach

Vanderbilt said the feature arrived with little advance notice and without an initial option to disable it. After months of use, testing and discussions with Turnitin and other universities, it disabled the detector on 16 August 2023 for the foreseeable future. The university cited false-positive risks, limited transparency and concerns about AI detectors' treatment of writing by non-native English speakers. It directed instructors toward clearer expectations, conversations with students and revised assessments.

Results

No published figures

Takeaway

The university received a consequential assessment feature before it had enough information to judge its reliability. Its subsequent review led it to remove the feature from the teaching workflow.
