Washington state voters have enacted Initiative 638, a new law that bars students defined as biologically male from competing in girls’ K‑12 athletic competitions. The measure, which passed with roughly 56.6% support according to Axios, also requires any student seeking to join a female‑only sport to provide a health‑care provider’s statement confirming biological sex based on reproductive anatomy, genetics, or naturally produced testosterone levels.
What the Initiative Requires
Under I‑638, schools must obtain a verification form from a qualified health professional before allowing a student to participate on a girls’ team. The law does not dictate which specific tests must be used, leaving providers the discretion to rely on existing medical records. The Washington Interscholastic Activities Association (WIAA) has noted that its current sports‑physical guidelines already do not require genital, DNA, or hormone testing.
Support and Opposition
State Democratic Party Chair Shasti Conrad called the measure “unconstitutional on its face” and said the party would back groups that challenge it in court. However, the party also clarified it would not be the one filing lawsuits. Conservative and faith‑based organizations, as well as many parents, have welcomed the initiative as a protection of fairness in school sports and a reinforcement of traditional values.
Critics, including the Gender Justice League and the ACLU of Washington, have expressed concerns that the law could lead to invasive examinations. Let’s Go Washington, the group that sponsored the measure, argues that existing medical records are sufficient and that no genital exams are required.
Legal and Legislative Context
I‑638 overturns a Washington policy that allowed students to compete on teams consistent with their gender identity, a rule in place for two decades. The measure is the third successful initiative from Let’s Go Washington’s 2026 ballot slate, following the approval of I‑001 (parental‑rights related) and the rejection of I‑645 (a tax repeal).
While the initiative is set to take effect on December 3, pending certification of the election results, several legal challenges are already being considered. The Gender Justice League is evaluating options, and the ACLU declined to comment on potential litigation.
Local Incidents Highlight the Debate
Recent incidents in Washington schools have brought the issue into sharp focus. In Camas, a group of girls walked off the cross‑country course to protest a transgender teammate’s participation. The district and WIAA said the student’s participation complied with existing rules at the time.
In Puyallup, a transgender student was accused of sexual assault during a girls’ wrestling match, leading to a family lawsuit and a pending Supreme Court emergency relief request. Additionally, a Title IX dispute arose in Tumwater after a girl refused to play against a transgender opponent, prompting a Department of Education inquiry.
What This Means for Families
For parents who value fair competition and clear biological standards in school sports, Initiative 638 represents a legislative affirmation of those principles. The measure also underscores the ongoing national conversation about how best to balance inclusion with competitive equity in youth athletics.
