Initiative 638 is a 2026 ballot initiative proposing the amendment of Washington state law. The initiative would require students participating in K-12 sports to submit medical documentation that verifies their “biological sex” as female. This would prohibit transgender girls from competing in school athletic activities intended for females, and would require healthcare providers to verify a student’s biological sex to determine eligibility. -Wikipedia

Does the text of Initiative 638 mention genital checks? It appears to be about making participation in sports based on sex, which may only involve a cheek swab to determine. there is enough fear going around without worrying about things the initiative doesn’t say
