"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 based solely on biological sex. It prohibits male-identified students from joining female-designated teams unless they provide a physician's statement confirming biological sex through anatomy, natural testosterone levels, and genetic analysis. Schools maintaining separate female teams cannot face complaints or penalties for this policy, and students harmed by violations can seek legal remedies. The law directly affects all K-12 and college athletic programs in New Jersey.
