Revises provisions relating to athletics. (BDR 34-179)

AB 240 requires public and private schools (including colleges) to designate athletic teams based on biological sex at birth as male-only, female-only, or co-ed, and prohibits enrolling students of the opposite sex in single-gender teams. It states that following this rule does not constitute sex or gender identity discrimination under state law and protects schools from adverse actions by athletic associations for enforcing it. The bill also allows students to sue schools or athletic organizations for violations or retaliation when reporting them, and permits schools to sue entities that penalize them for compliance. These provisions apply to both K-12 schools and higher education institutions.
