Bill > HB4066

This bill requires school districts, intermediate school districts, and public school academies participating in interscholastic athletics to designate sports teams based on biological sex, specifically creating separate teams for females, males, and coeducational/mixed sports. The legislation prohibits individuals of the male sex from participating in sports teams designated exclusively for females. The bill defines "sex" as the biological indication of male or female listed on an individual's original birth certificate. Schools that violate these provisions could face legal consequences, as the bill provides private cause of action for students who are deprived of athletic opportunities or experience retaliation. Additionally, the bill protects schools from adverse actions by state agencies or athletic associations for maintaining single-sex athletic teams. Importantly, the bill does not restrict male or coeducational team participation, and any civil actions resulting from violations must be initiated within two years of the occurrence. The legislation aims to preserve competitive fairness in school sports by ensuring that female athletes compete primarily against other biological females.
