What happened
In December 2023, two Hingham High School students ("RNH" and unnamed) reportedly used Grammarly to create a script for an AP U.S. History project. The AI-generated text included fabricated citations to nonexistent books, which the student copied and pasted without verification or acknowledgment of AI use. This violated the school's academic integrity policies, leading to disciplinary action. RNH's parents later sued the school district, but a federal court ruled in favor of the school.
