Voters in two Democratic-led states will decide on Nov. 3 whether to bar transgender girls from girls’ school sports, creating the first direct statewide votes on a policy already enacted by 27 states.

Washington’s Initiative 638 would govern K–12 athletics and require a health-care provider to verify the sex of every student seeking to compete on a girls’ team. Colorado’s Proposition 134 would reach both K–12 and college sports, requiring schools and athletic associations to classify teams as male, female or coeducational. The AP reported Saturday that the issue has never previously gone directly to voters.

The votes arrive four months after the Supreme Court upheld bans in Idaho and West Virginia. That ruling permits states to restrict participation by sex without violating Title IX or the Constitution; it does not require states to do so. The distinction leaves educators, athletic associations and families confronting a policy question that courts have now largely returned to elected officials and voters.

Voters Take Over From Legislatures

Both ballot campaigns bypassed Democratic-led legislatures that had not adopted comparable bans. Washington’s measure was submitted to lawmakers as an initiative to the legislature; after lawmakers did not act, it advanced to the general-election ballot. The official text would replace current eligibility rules with a sex-based standard for female competitions.

Colorado voters face a statutory proposal covering public and private schools, colleges, intramural programs and athletic associations. The state’s official Blue Book explains that Proposition 134 would also restrict government, licensing and accrediting bodies from penalizing schools for maintaining sex-separated teams. A girl could join a male-designated team when no corresponding female team is available.

The Measures Differ in Reach and Verification

Washington’s proposal is narrower in institutional scope but more explicit about documentation. It requires a provider’s signed statement based on reproductive anatomy, genetic makeup or naturally produced testosterone levels. It does not prescribe one test or inspection. Supporters told the AP that medical history could make verification routine; opponents said unclear procedures could lead to invasive or expensive testing and discourage participation among students who are not transgender as well.

Colorado’s measure defines eligibility through reproductive biology but does not impose Washington’s provider-signature system. It gives the state education commissioner enforcement authority over K–12 districts, while institutions and athletic associations would implement team classifications across school and collegiate sports. For administrators, those differences matter: one state would create a documentation process for individual athletes, while the other would impose a wider classification rule across more institutions.

In West Virginia v. B.P.J., the Supreme Court held 6–3 that West Virginia’s sex-based classification satisfied constitutional review. All nine justices agreed that Title IX allows schools to maintain separate teams defined by biological sex. Justice Brett Kavanaugh’s opinion emphasized competitive fairness and safety; the dissent argued that a categorical rule imposed substantial costs on transgender students without sufficiently accounting for individual circumstances.

The decision cleared a federal legal path for state bans, as Reuters reported in June. But it did not invalidate policies in states that continue to permit participation consistent with gender identity. Washington and Colorado therefore present a different test: whether voters in states with inclusive rules will choose the authority the court said states may exercise.

Public Support Exceeds the Available State Data

The ballot campaigns are unfolding against broad national support for restrictions. A June Quinnipiac poll found that 70% of 1,165 registered voters said transgender women and girls should not be allowed on female school teams, while 24% said they should. The survey’s margin of error was 3.4 percentage points. Democrats were nearly evenly divided, helping explain why supporters see Washington and Colorado as tests of whether the policy can win outside Republican-led states.

The scale of direct participation is much less certain than public opinion. The AP found that neither state maintains an official count of transgender girls in school sports. Evidence about athletic advantage also varies by age, sport, puberty and hormone treatment, complicating claims that any single result applies uniformly to every athlete or competition. The policy choice is therefore broad even though the population directly affected appears small and is not precisely measured.

The Educator's Takeaway

For school leaders, the immediate issue is not predicting the outcome but identifying which procedures would change if either measure passes. Washington districts would need a consistent provider-verification process, privacy safeguards for medical information and guidance on disputed or incomplete records. Colorado schools and colleges would need team classifications, eligibility rules and a clear division of authority among institutions, athletic associations and the state commissioner. In both states, staff communication will matter because the Supreme Court decision establishes what states may do, not what current local policy already requires. Administrators should also distinguish unresolved implementation questions from campaign claims: neither ballot text supplies a comprehensive answer for every medical, privacy or enforcement dispute likely to arise.

What Comes After Election Day

If either measure passes, regulations, athletic-association rules and possible implementation litigation will determine how the new policy works in practice. If voters reject the proposals, supporters may still treat the margins as a guide for future ballot drives elsewhere. Either result will extend beyond two states: the votes will show whether a court-approved restriction can gain direct public endorsement in jurisdictions whose legislatures have chosen a different approach.
