Five-second answer

Claim we investigated

Initiative 638 will require genital examinations for female athletes.

False. The text lets providers verify sex by genetic testing or testosterone levels instead; no genital exam is mandated. The initiative's filed text and the Attorney General's ballot summary both list three alternative verification bases, any one of which suffices, so the measure contains no genital-examination mandate.

One-minute summary

What the evidence establishes

  • Section 3(2) of the initiative requires a provider-signed statement verifying biological sex for students entering female-only competition.
  • The provider may rely on one or more of three bases: reproductive anatomy, genetic makeup, or normal endogenously produced testosterone levels. Any one suffices, so no genital examination is required.
  • The text names what the provider may rely on, not a procedure the student must undergo. It mandates no specific exam or test, and it does not rule out a student's regular doctor signing based on what they already know from past care, an approach a pediatrician who supports the measure described to KUOW. Whether that is accepted will depend on implementing guidance.
  • The Washington Attorney General's ballot summary describes the same three alternatives.
  • Current sports physical forms contain no genital exam and no sex field, so any verification would be a new step.
  • Reporters and opponents say an anatomy check may be the most accessible route for many families, because genetic and hormone tests may cost more; how it would work in practice is still undetermined.
  • The text gives coaches and school staff no role in examining students; verification comes from the student's own health care provider.
Important context: Initiative IL26-638 is on Washington's November 3, 2026 ballot. It would bar students it defines as biologically male from female-only interscholastic competition and require every student entering those activities to submit a statement from the student's personal health care provider verifying biological sex. This check addresses only whether the measure requires a genital inspection, not whether the policy is wise, fair, or lawful.

Primary legal text review Washington Secretary of State United States 2025 Initiative Measure No. IL26-638, filed June 2, 2025, adds a new section to chapter 28A.600 RCW. Section 3(2) requires a student who elects to compete in female-only individual or team activities to provide, as part of the required sports physical, a statement signed by the student's personal health care provider verifying the student's biological sex, relying only on one or more of reproductive anatomy, genetic makeup, or normal endogenously produced testosterone levels. The phrase one or more means any single basis can suffice. The text names no examination procedure and assigns no role to school staff. The text does not define biological sex or personal health care provider, does not say whether prior medical records may be used, and sets no testosterone threshold. Its practical effect depends on implementing rules that have not been written. Washington Secretary of State

5. Supporters and opponents read the same text differently

The Washington State PTA, which opposes the measure, argues that because insurers are unlikely to cover genetic or hormone testing, an intimate exam would become the practical price of play for many girls, and that the testosterone option is clinically unreliable. A pro-initiative column in the Everett Herald, responding to opponents who described mandatory genital exams, argues that a genetic marker or hormone level alone satisfies the text and that no school official inspects a child. Both agree the text lists three alternatives; they disagree about which would be used in practice.

Limit: Both sources are advocacy: the PTA opposes the measure and the Herald column supports it. Neither is a neutral analysis, and their predictions about costs and insurance coverage are not independently documented.

Common questions

“The anatomy route is the only realistic one, so the measure effectively requires a genital exam.”

Cost and insurance may lead some families toward an anatomy-based check, and implementing guidance has not been written. But a likely outcome for some is not a requirement for all. The text explicitly lets a provider rely on genetic makeup or testosterone levels instead, and it does not rule out reliance on previous examination records. A student who uses either alternative never needs a genital exam, so the claim that the measure will require one is false.

“Sports physicals already document sex, so nothing would change.”

The initiative's own findings make this assertion, but the standard PPE examination form posted by the WIAA has no field for sex and no genital exam, and a WIAA official told KUOW that participation does not currently require a sex sign-off. Verification would be a new step.

“Coaches or school officials would inspect girls.”

The text places verification with the student's personal health care provider, as part of the sports physical. It assigns no examination role to coaches, school staff, or the WIAA.

“Only girls must be verified.”

Accurate. Section 3(2) applies to students who elect to compete in activities intended for female students only. No comparable requirement applies to boys' or open activities.

Conclusion

The claim that Initiative 638 will require genital examinations is contradicted by the measure's own text. Section 3(2) requires a provider-signed statement verifying biological sex and says the provider may rely only on one or more of three bases: reproductive anatomy, genetic makeup, or normal endogenously produced testosterone levels. Because any single basis suffices, a student can satisfy the requirement through a genetic test or a testosterone test with no genital examination at all. The Attorney General's neutral ballot summary describes the requirement the same way. No provision of the measure mandates a genital examination, and none assigns coaches or school staff any role in examining students. Confidence is High because the claim is about what the measure requires, and that question is answered directly by the filed text and confirmed by the state's official summary. This rating does not depend on predictions about implementation. The broader concern behind the claim deserves a separate answer. Standard sports physicals contain no genital exam and no field for sex, so any verification would be a new step. KUOW reported that a visual exam would likely be the most accessible route for many students, and the Washington State PTA argues insurers may not cover genetic or hormone testing. A pediatrician who supports the measure told KUOW that providers could rely on findings from earlier well-child visits, though the text does not say whether prior records qualify. These points bear on a different claim, that many girls may end up choosing or being steered toward an anatomy-based check; that claim is plausible but unproven, and depends on cost, insurance coverage, and implementing guidance that does not yet exist. It does not make the stronger claim, that the measure requires genital examinations, accurate. FactHub rates what was said, not the intent of those who said it.

How we checked

  1. Defined the claim precisely: whether Initiative 638 requires a genital inspection for female athletes, as opposed to permitting one or making one likely.
  2. Read the full filed text of IL26-638 from the Washington Secretary of State, focusing on Section 3(2).
  3. Compared it with the Attorney General's ballot title and summary, a separate official restatement.
  4. Reviewed national sports-physical guidance (PPE5, via American Family Physician) and the PPE examination form posted by the WIAA to establish current practice.
  5. Reviewed independent news reporting (KUOW) that interviewed physicians on both sides and the WIAA.
  6. Compared the readings of an opposing organization (Washington State PTA) and a supporting opinion column (Everett Herald).
  7. Archived every source with the Wayback Machine and recorded limits for each line of evidence.

Editorial note: Scope: this article rates only the claim that Initiative 638 requires genital inspection for female athletes. It does not evaluate the measure's broader merits, its likely legal challenges, or claims about the number of transgender athletes. The initiative's practical effects depend on implementing guidance that does not yet exist; this check will be revisited if the measure passes. Quotations from the initiative are from the public filed text. No external specialist review has been recorded.

Update history

  1. First draft.
  2. Reworded the rated claim to match how opponents state it ("will require genital examinations") and changed the rating from Misleading (moderate confidence) to False (high confidence), since the claim concerns what the measure requires and the text contradicts it. Moved discussion of likely practical effects to a separate, unrated point.
  3. Retitled to state the finding more generally, and added a key point setting out the full range of verification routes the text permits.
