Google Put AI in Schools. Test Scores Plummeted.

OECD data links student AI chatbot use to a 20-point test-score drop, prompting NYC and LA to restrict Google's Gemini in classrooms.

• OECD test score drop: A global survey of 750,000+ teens found US reading scores fell 14 points (2022-2025), with students reporting AI use for schoolwork scoring 20 points lower than non-users — equivalent to a year of schooling.
• Google's AI is everywhere: Gemini is embedded in Google Search (AI overviews/AI mode), Google Classroom, Docs, Slides, and apps like PhotoMath, reaching nearly every US student via Chromebooks.
