Removes an expiration date of provisions governing participation in athletics competitions

HB 2145 removes an expiration date from Missouri's existing law that governs participation in interscholastic and intercollegiate athletics. The bill mandates that schools and universities must base athletic eligibility on the biological sex recorded on a student's official birth certificate, with the only exception allowing female students to compete in male-designated events if no female equivalent is available. Institutions that violate these rules by allowing students to compete in the opposite sex designation risk losing state funding, while affected students or parents can seek legal remedies for denied opportunities. Additionally, the legislation requires state education departments to create implementing regulations that comply with medical confidentiality laws.
