Washington SB5097

The competitiveness rules adopted under this section must [... ensure] ample opportunities for all student athletes to participate in appropriately competitive events and contests that align with the skill level of the competitors regardless of gender identity; and (b) Appropriately consider the effects of physiological and hormonal variation among athletes as it relates to the competitiveness and safety of events and contests, which may include rules that permit the exclusion of individual competitors from girls' athletics events and contests where the competitor would have an unfair advantage based on endocrine characteristics.

Rules adopted under this section may not authorize a sex verification or dispute process, but may require age-appropriate sampling for relevant hormone levels to determine whether an individual will have an unfair competitive advantage or pose a safety risk in a girls' event or contest.

Interscholastic athletic teams, events, and contests are encouraged to be organized into distinct activities for boys and girls.
