AB 1159 Expands Student Data Privacy Protections, Bars Operators From Using Student Data to Train AI
California's AB 1159 expands privacy protections for students and prohibits operators of educational platforms from using student data to train AI models. The law tightens restrictions on how companies that serve schools can handle the information they collect from minors.
Why this matters: Kids using school apps generate a lot of data. Until now, companies running those platforms had real room to repurpose that data, including feeding it into AI systems. AB 1159 closes that door. This matters because student data is not ordinary data. It includes behavior, learning struggles, and personal history collected in settings where kids have no real choice about participation. A company should not get to train its products on that just because a school handed over access.
