Defending equity in interscholastic sports.

HB 1699 (Defending equity in interscholastic sports) requires Washington public school districts to verify a student’s biological sex through a healthcare provider’s statement (based on reproductive anatomy, genetics, or testosterone levels) before allowing biologically male students to participate in female-identified sports. It permits schools to prohibit biologically male students from competing in sports with separate male/female classifications, while mandating equal resources (equipment, facilities, coaching, etc.) for all gender-segregated teams. The bill amends existing laws (RCW 28A.600.200 and 28A.640.020) to align with these provisions and requires the superintendent to develop guidelines eliminating sex discrimination in school activities. It directly affects public school students, athletic programs, and district policies governing interscholastic sports participation.
