The bill introduced, SF No. 802, aims to regulate participation in school athletic programs and the use of facilities like restrooms and locker rooms based on sex, which is determined by chromosomes and identified by anatomy. Key points include:

1. Athletic Teams: For students aged 12 or older, or in 7th grade and higher, athletic teams can be restricted to one sex if that sex has had limited athletic opportunities historically. For younger children, teams should be co-ed unless there’s a clear interest and historical limitation for one sex, which may then have its own team.

2. Equal Treatment: If a school has separate teams for boys and girls in the same sport, each team must receive substantially equal funding and treatment, though they won't be required to have joint practices.

3. Wrestling Teams: These can be restricted to one sex regardless of past opportunities, but both sexes must have equal access to programs if there is sufficient interest.

4. Student Physical Privacy: Public school facilities such as restrooms, locker rooms, and showers must be designated and used exclusively based on sex. Facilities designated for the female sex cannot be used by anyone with a Y chromosome. Schools must also provide safe and private areas for students in various states of undress based on their sex. Accommodations like single-occupancy facilities may be made for special circumstances, but not for use by the opposite sex.

This legislation defines sex strictly based on biological characteristics and reinforces separate facilities and programs based on this definition, while also allowing for some exceptions in athletic programs.
