Stanford's Institute for Human-Centered AI released its ninth annual AI Index Report on April 13, and while the headlines fixated on benchmark battles and $581 billion in global AI investment, the most consequential findings for educators are buried in chapter seven. Between 50% and 84% of U.S. high school and college students now use AI for schoolwork — with some schools reporting 100% adoption. Yet only half of middle and high schools have any AI policy at all, and a mere 6% of teachers describe their school's AI policies as clear.
Students most commonly use generative AI for research, essay editing, and brainstorming — three activities at the heart of how schools have traditionally measured learning. Forty-seven percent of students said they have wanted to use AI for schoolwork but were unsure whether it was allowed, suggesting that ambiguity itself is shaping behaviour. Among teachers, 81% of CS educators agree AI should be included in foundational learning, yet fewer than half feel equipped to teach it. Only four US states include AI within their computer science standards.
The global picture adds urgency: China and the UAE both mandated AI education starting with the 2025–26 school year. The report, produced with the Kapor Foundation, CSTA, and ECEP Alliance, is one of the few comprehensive AI datasets not produced by organisations with a financial stake in AI adoption. Dan Fitzpatrick notes that one Manhattan school surveyed its middle and high school students and found 100% were using AI — making the "policy gap" not a future problem but a present failure.
