Bill > SB117

This bill requires educational institutions (including public schools, independent charter schools, and private schools participating in a parental choice program) to designate athletic teams and sports based strictly on biological sex as determined at birth and recorded on a birth certificate. Specifically, the bill mandates that schools create separate athletic teams or sports categories for males and females, and explicitly prohibits male students from participating in female-designated sports or using female locker rooms. The legislation defines sex as the biological sex assigned by a physician at birth, and provides legal recourse for female students who are denied opportunities or face adverse consequences due to male students participating in female sports. The bill allows female students to bring lawsuits against educational institutions if they are prevented from participating in sports or suffer harm as a result of violations of these rules. Additionally, the bill requires educational institutions to provide written notification to students and parents if they intend to change the designation of an athletic team or sport. This legislation appears to be aimed at maintaining sex-specific athletic competitions and protecting what the bill's sponsors likely view as fair competitive opportunities for female athletes.
