Fairness in Girls’ Athletics (Initiative Measure No. IL26-638) goes to Washington voters this fall. It would ban male students from competing in K–12 girls’ sports.
The initiative would require school districts and nonprofit sports organizations to prohibit biologically male students from competing with and against female students in sex-separated sports — individual or team events intended for females only.
The Washington Interscholastic Activities Association currently allows participation consistent with gender identity.
Twenty-seven states have enacted similar sex-based sports rules. On June 30, 2026, the U.S. Supreme Court held in West Virginia v. B.P.J., decided together with Idaho’s Little v. Hecox, that Title IX and the Equal Protection Clause allow states to reserve girls’ and women’s teams for biological females. The ruling permits those state rules. It does not require every state to adopt one.
Let’s Go Washington, the campaign behind the measure, gathered enough signatures to send Fairness in Girls’ Athletics to the Legislature. Lawmakers referred it to the November ballot instead of acting on it in the 2026 session.
