Massachusetts: fired teacher asks court to vacate an arbitration, saying the arbitrator improperly used AI tools to judge her AI-detector evidence
A kindergarten teacher at a public elementary school in Concord, Massachusetts, was dismissed in August 2025 after an unsatisfactory evaluation. In arbitration she argued that some of the principal's evaluations may have been produced with AI, relying on GPTZero estimates; the principal denied using AI beyond grammar checks. According to the arbitration decision as reported by The Concord Bridge, the arbitrator stated in an appendix that he used two AI tools, GPT-5.4 and Claude Opus 5, to research whether GPTZero was reliable, checked some of the sources they supplied, concluded that GPTZero's results deserved no weight, and upheld the dismissal on 27 August 2026. On 28 September 2026 the teacher asked Suffolk Superior Court to vacate the decision, alleging that the AI-assisted research was an improper investigation outside the hearing record that the parties were not told about or allowed to challenge. These are allegations in a complaint; the district declined to comment and no court has ruled.
