Relating to intercollegiate athletic competitions based on biological sex.

HB 3186 requires out-of-state colleges competing against Texas public universities in intercollegiate athletics to certify 30 days before the event that they will follow Texas' biological sex-based team eligibility rules. It directly affects out-of-state institutions competing against Texas schools in sports, mandating this certification to ensure compliance with Texas' policy. The bill adds this certification requirement to the Education Code, applying to all such competitions starting in the 2025-2026 academic year. It does not alter existing rules for Texas schools or individual athlete eligibility.
