Washington Voters Approve Initiative Separating Boys and Girls Sports
· Confirmed
In Short: The initiative says the provider may verify sex as part of a routine sports physical, relying only on reproductive anatomy, genetic makeup, or normal naturally produced testosterone levels.

Tumwater High School student Frances Staudt, who has been campaigning for the initiative for two years, broke down in tears at a watch party hosted by Let's Go Washington, the organization that spearheaded the initiative.
Supporters of the initiative argue that it protects fair competition and opportunities for girls. As of Tuesday night, Initiative 638 leads with nearly 57% of the total votes counted thus far, according to the Washingtonstatestandard.
Initiative 638 would rely on 'one or more' of the following methods to determine biological sex: 'the student’s reproductive anatomy, genetic makeup, or normal endogenously produced testosterone levels,' according to the initiative.
"We’ve consistently recognized the inherent biological and physiological differences that give male athletes a competitive advantage in most sports," said Michael Cannon, school board director.
Opponents of I-638 argue that the verification requirement would affect all girls who play, not just transgender girls. Dr. Libby Loft, a Spokane family physician who opposed the measure, said the initiative’s text bars using a birth certificate, leaving providers with an anatomical exam, a testosterone test, or chromosome testing— the last two costing $162 and $1,310 without insurance.
Supporters of I-638 said the measure protects fair competition and opportunities for girls and adds one step to an existing process.
