Should states require students to verify their biological sex to participate in school sports?
Washington residents will vote on Initiative 638 this November 2026, which proposes barring transgender girls from competing in girls sports at K-12 schools. The initiative would require students to provide medical documentation of their biological sex to participate in these competitive athletic programs.
Why it matters
Proponents argue the initiative ensures competitive opportunities for girls, while opponents contend the mandate forces students into invasive physical and genetic examinations. The debate centers on the balance between sports equity and privacy rights for students in public schools.
Initiative 638 requires verification of biological sex through reproductive anatomy, genetic makeup, or testosterone analysis. A recent survey of 400 voters shows 43% support for the measure.
