"Fairness in Women's Sports Act."

This bill requires New Jersey public and private schools participating in athletic associations (like NJSIAA or NCAA) to designate sports teams as "male," "female," or "coed" based solely on biological sex. It prohibits students assigned male at birth from joining female-designated teams, requiring disputed cases to be verified through a physician's statement confirming reproductive anatomy, natural testosterone levels, and genetic makeup. The law protects schools from penalties for maintaining sex-segregated teams and provides legal remedies for students denied athletic opportunities or facing retaliation due to violations. It directly affects all K-12 schools and colleges in New Jersey affiliated with major athletic associations.
