SB 1 mandates that students participate in school sports and use facilities based on their biological sex at birth, as documented on their birth certificate. The bill explicitly excludes transgender students from joining teams or using shared spaces aligning with their gender identity and outlines financial penalties for schools that violate the transgender athlete ban. Among other changes, the substitute language replaces all references to “gender” in the code section with “sex”, allows for someone who believes they’ve been harmed by another person violating this law to seek damages, and expands the application to include private schools that receive state funding.
