Washington voters have passed Initiative 638, a measure that retricts transgender girls from competing in female school sports. The initiative secured a majority with 56.74% of the vote, establishing new biological requirements for eligibility.

The $1,310 price tag for chromosome testing

Opponents of Initiative 638 argue the new rules introduce significant financial hurdles for families. Dr. Libby Loft, a family physician in Spokane, highlighted that the law moves away from simple birth certificate verification toward more invasive and costly medical tests.

Medical verification requirements under the new law include reproductive anatomy, genetic makeup, or testosterone levels, according to the report.. This could lead to unexpected expenses for students, including:

  • Chromosome testing: $1,310 without insurance
  • Testosterone tests: $162 without insurance
  • Opponents, including the Washington State Nurses Association, have expressed concern that these requirements might inadvertently impact all female athletes seeking to prove eligibility.

    A policy for 200,000 athletes and 10 individuals

    The scale of the impact remains a point of intense debate between supporters and critics. State officials estimate that only five to 10 transgender athletes compete among more than 200,000 student-athletes across Washington. Despite these low numbers, supporters argue the principle outweighs the statistics.

    Hallie Herzberg, a spokesperson for Let's Go Washington, argued that even a single girl losing a podium spot justifies the measure. Supporters of the measure, such as Moms for Liberty, view the change as a necessary restoration of a "sex checkbox" that was removed from sports physical forms in 2019.

    The legal pivot from WIAA's previous stance

    The new law marks a significant departure from how the Washington Interscholastic Activities Association (WIAA) previously managed gender identity. Before the vote, the WIAA allowed students to participate in programs that aligned with their gender identity. In April, WIAA member schools held a 29-24 vote to adopt a proposal limiting girls' sports to biological females, but the association initially declined to implement it because it conflicted with existing state law.

    The passage of Initiative 638 provides the legal framework that was previously missing in Washington state . This move follows a broader national trend, with 27 states already having similar laws on the books.. This legal landscape was further clarified by a recent U.S. Supreme Court ruling which determined that state laws barring transgender athletes do not violate the 14th Amendment or Title IX.

    The missing instructions for medical verification

    A significant gap in the new law is the lack of procedural clarity for healthcare providers . While the initiative mandates that a provider must sign a statement verifying biological sex , the text does not specify the exact methodology for gathering this data. As the source reports, verification can rely on anatomy, genetics, or testosterone, but the specific "how" remains unaddressed.

    This ambiguity leaves several questions for school districts and medical professionals regarding implementation :

    • Will schools be responsible for coordinating these specific medical tests?
    • How will the privacy of students be protected during anatomical or genetic examinations?
    • Will the Seattle School Board or King County Council find ways to mitigate the costs for low-income families?
