A 2025 OECD PISA study of over 760,000 15-year-olds across 91 countries found that, after controlling for socioeconomic status, students who never use AI generally outperformed AI users in science. The performance gap was largest for those using AI to summarize texts or draft assignments, and for those using it either rarely or daily, while moderate, intentional use—especially paired with training to critically evaluate AI outputs—showed smaller drops or even slight gains over non-users.
