AB 102 Wisconsin Assembly · 2025-2026 Regular Session

Relating to: designating University of Wisconsin and technical college sports and athletic teams based on the sex of the participants.

AB 102 requires University of Wisconsin and technical college athletic programs to designate intercollegiate and club sports teams exclusively for "males" or "females" based on birth sex as recorded on a student's birth certificate. It prohibits students assigned male at birth from participating on teams designated for females or using female-designated locker rooms. The bill creates legal remedies for female students denied participation or harmed by violations, and for institutions facing penalties for compliance. It applies to all such teams starting in the first semester after the law takes effect, overriding existing anti-discrimination protections for these specific athletic contexts.

Bill Text → Text as Enrolled · 3 edits

MINOR

The bill was vetoed in full by the Governor, preventing it from becoming law. The original version required universities and technical colleges to designate sports teams based strictly on sex determined at birth and prohibited male students from using female locker rooms. The vetoed version would have also allowed coed teams and included specific provisions for locker room access and privacy accommodations.

Scope change

The bill's scope was reduced to null because the entire text was removed due to a gubernatorial veto.

ENFORCEMENT

All provisions requiring institutions to designate sports teams based on biological sex and prohibiting male students from participating in female-designated teams or using female locker rooms were removed.

DEFINITION

The specific definition of 'sex' as the condition determined by a physician at birth was removed.

REQUIREMENT

Requirements for institutions to explicitly label teams as 'males,' 'females,' or 'coed' and to notify students of changes were removed.
