AB 1159 California Assembly · 2025-2026 Regular Session

Student personal information.

Summary
Existing law, the K–12 Pupil Online Personal Information Protection Act (KOPIPA) , generally protects the personal information of a student enrolled in a K–12 course of instruction, defined as a "pupil," by prescribing requirements and prohibitions applicable to an operator of an internet website, online service, online application, or mobile application with actual knowledge that the site, service, or application is used primarily for K–12 school purposes and was designed and marketed for K–12 school purposes. Existing law, the Early Learning Personal Information Protection Act (ELPIPA) , generally protects the personal information of a child enrolled in a preschool or prekindergarten course of instruction, defined as a "pupil," by prescribing requirements and prohibitions applicable to an operator of an internet website, online service, online application, or mobile application with actual knowledge that the site, service, or application is used primarily for preschool or prekindergarten purposes and was designed and marketed for preschool and prekindergarten purposes. This bill would instead apply the provisions of KOPIPA and ELPIPA to an operator, or an entity working on behalf of the operator, of an internet website, online service, online application, or mobile application with actual knowledge that the site, service, or application is used for the applicable school purposes and was designed or marketed for those purposes, as specified. The bill would, among other changes to KOPIPA and ELPIPA related to protecting the personal information of students, prohibit an operator from using covered information, as defined, including persistent unique identifiers, created or gathered by the operator's site, service, or application to train a generative artificial intelligence system or service or develop an artificial intelligence system. This bill would also enact the Higher Education Student Information Protection Act (HESIPA) , which would generally protect the personal information of a student enrolled in a higher education institution, as defined, in a similar manner as KOPIPA and ELPIPA. The bill would make HESIPA operative on July 1, 2027. This bill would authorize a pupil or student actually harmed by noncompliance with KOPIPA, ELPIPA, or HESIPA to bring a civil action against the noncompliant operator, as prescribed, and would require a person bringing that action to furnish a copy of the complaint to the Attorney General within 10 days after filing the action.

MODERATE
The August 21 Senate amendment to AB 1159 strengthens deidentification requirements by requiring school review before any use of deidentified data and giving local educational agencies authority to determine what constitutes sufficient deidentification. It also adds new exceptions permitting sales and disclosures of student data by national assessment providers and nonprofit enrollment data reporting entities under contract restrictions, extends the pre-litigation notice and cure periods from 45/30 days to 60/60 days, and adds a provision clarifying that schools are not required to review or approve deidentification processes.
REQUIREMENT

Deidentification review timing changed: operators must now submit deidentification processes for school or LEA review BEFORE any use of deidentified data, rather than merely making them available upon request.

Deidentification standard changed: measures must now be 'consistent with those required of educational agencies and institutions under FERPA... as determined by the local educational agency,' giving LEAs authority to set the deidentification standard.

ELIGIBILITY

New sale exception (subparagraph (B) of subdivision (b)(3)) permits sales of pupil data by national assessment providers to schools, LEAs, higher education institutions, scholarship-granting organizations, or their service providers under a written contract prohibiting further sale or disclosure, and sales by nonprofit enrollment data reporting entities for graduation verification.

New disclosure exception (subparagraph (F) of subdivision (b)(4)) mirrors the new sale exception, permitting disclosures by national assessment providers and nonprofit enrollment data reporting entities under contract restrictions.

TIMELINE

Pre-litigation notice period before filing a civil action extended from at least 45 days to at least 60 days.

Operator cure period after receiving pre-litigation notice extended from 30 days to 60 days.

SCOPE

New subdivision (q) clarifies that the section does not require a school or LEA to review an operator's deidentification processes or to approve an operator's retention or use of deidentified information, creating a safe harbor for schools that choose not to engage in such reviews.
