New York City and Los Angeles Unified, the two largest public school systems in the United States, have moved to restrict student use of generative AI for the coming school year. New York City banned student-facing AI in kindergarten through eighth grade classes, allowing only a limited set of approved tools for high schoolers. Los Angeles Unified placed a one-year moratorium on generative AI on district devices for all of its roughly 378,000 students.

The two announcements arrived on the same day, within hours of each other, ahead of the start of the 2026-27 school year. The Los Angeles decision reportedly caught some of the district's own officials by surprise, since LAUSD had previously issued screen time limits but no specific rules on AI.

The move reverses more than three years of drift toward more permissive rules. Both districts were the first large systems to block ChatGPT in late 2022 and January 2023, then loosened those bans within months. New York City's most recent attempt at a framework, a risk-rating scheme drafted in March, was withdrawn after criticism, and the district paused software purchases over the summer.

The restrictions followed sustained pressure from parent and teacher groups. In New York the AI Moratorium Coalition called the partial pause a step in the right direction, while parents in Los Angeles with the group Schools Beyond Screens learned of the ban at the committee meeting where it was announced.

The full account of both decisions, including the earlier policy fights, is reported by Tech Policy Press.

Teacher organizers say the rules do not go far enough. They want limits extended to high schoolers and to staff use, plus metrics for evaluating approved tools. Both districts now have a year to write longer-term policy, and earlier rollbacks drew organized opposition.

For founders, the practical effect is a closed door at two of the biggest buyers in K-12 education. District deals already follow school-year calendars, so a one-year pause at systems that large pushes student-facing products onto the next procurement cycle, with the details set by whichever longer-term policy arrives in 2027. Tools aimed at teachers, administrators and back-office work sit outside the restrictions, and the note is that these two districts often set the tone other systems follow.
