Initiative 638 Passes in Washington: What It Does and What Comes Next

01

What Initiative 638 actually says

Initiative 638 tells school districts, and the nonprofit bodies that run interscholastic sports, to bar students it calls “biologically male” from competing with or against girls in sports meant for girls. That is the summary Ballotpedia records from the measure. It covers individual events and team events alike.

The second half of the measure is the part that reaches further. A student who wants to play on a girls’ team must hand in a statement from a healthcare provider verifying her sex. The measure names three grounds a provider may use: reproductive anatomy, genetic makeup, or the testosterone levels a body makes on its own.

KATU reports that Initiative 638 covers all K-12 girls’ sports and that organisations which break it can face penalties. Students themselves face no punishment unless they knowingly break the rules or gain a significant advantage over another student. Boys’ teams carry no verification requirement at all, KIRO 7 notes.

On paper, Initiative 638 changes how two existing state laws are enforced. One gives school districts control of interschool athletics. The other governs the state superintendent’s rules against discrimination. The new rule now sits between them.

Read on its face, Initiative 638 is about school sport. Its summary speaks of interschool athletic activities and of the nonprofit bodies that regulate them. Families with questions about club, community or recreation teams should ask those organisations directly, because the reporting so far has not addressed them. College sport already runs under different rules: Legal Voice notes that NCAA policy restricts competitive women’s teams at member colleges to athletes assigned female at birth.

Every girl, not only trans girls

The campaign for Initiative 638 was about trans girls. The law it wrote is about every girl. A ninth grader trying out for volleyball, a twelfth grader on her fourth cross-country season, a seventh grader who has never thought twice about which team is hers: from December 3, each of them will need a doctor to put her sex in writing before she plays.

That was the heart of the No campaign’s case: opponents argued that Initiative 638 would require unnecessary testing for all girls. The Washington Interscholastic Activities Association, the body that runs school sports, knows of about ten trans students playing school sports in the whole state, KUOW and OPB report. To reach those ten, Initiative 638 puts a medical gate in front of every girl who plays.

OPB notes that other states with bans generally ask only for a birth certificate. This makes Washington one of the first states to require medical verification of sex for youth sports. KATU adds that genetic and hormone tests are costly, and nothing in the reporting so far says who pays.

Then there is privacy. A girl’s medical record is hers and her family’s. The new law sends a statement about her body to a school or an athletic association, and the reporting so far does not say who will hold it, who may read it, or how long it is kept. Those are fair questions for any parent to put to a school before December 3.

More than a hundred medical providers, organised through No Hate in WA State, spoke out against Initiative 638 before the vote, according to KATU. Doctors like them are the people the law now asks to sign these statements.

How Washington got here

Initiative 638 began as an initiative to the Legislature. Let’s Go Washington, led by Brian Heywood, filed it in June 2025 and turned in 445,187 signatures on January 2, 2026, according to Ballotpedia. The Legislature did not act on it before its session ended on March 12, so it went to the voters exactly as written.

Supporters included the state Republican Party, Moms for Liberty’s Washington chapter and the Washington State Catholic Conference. Opponents gathered as No Hate in WA State, a coalition that included the ACLU of Washington, the Washington Education Association and Gov. Bob Ferguson.

Heywood framed the result simply. “It wasn’t about transgender students. It was about girls,” he said, according to KUOW. Libby Watson, who ran the No campaign, saw it differently on election night, calling it “a very scary canary in the coal mine” for future policies aimed at LGBTQ+ Washingtonians.

Ballotpedia’s latest posted count shows Initiative 638 with about 56 percent of the vote, 1,178,877 yes to 919,438 no. Ballots were still being counted when the AP made its call, so the final numbers will shift slightly before the count is certified.

What the Supreme Court decided in June

Initiative 638 passed into a legal world the Supreme Court reshaped this summer. On June 30, 2026, in West Virginia v. B.P.J. and Little v. Hecox, the Court upheld Idaho’s and West Virginia’s bans by a vote of six to three. Justice Kavanaugh wrote that neither the Equal Protection Clause nor Title IX requires schools to let students compete by gender identity.

The decision was not as simple as its headline. Justice Sotomayor, joined by Justices Kagan and Jackson, dissented in part. She argued that the lower courts should first have settled questions of fact, such as whether trans athletes who never went through male puberty and receive hormone therapy keep any physical advantage. The Court sent both cases back for further proceedings.

Notice what the Court did not say. It did not say every state must ban trans girls from girls’ sports. Legal Voice, a regional legal advocacy organisation, puts it plainly: the decision does not require every state to adopt similar laws. It permits bans. It does not order them.

The federal government has pushed in the same direction. When the ruling came down, KATU reported that the administration has argued Title IX requires schools to separate teams by biological sex, and may tie federal funding to such bans. University of Oregon political scientist Allison Gash said the decision could make those efforts “more muscular.”

That matters for what happens to Initiative 638 next. A federal claim that a sports ban violates equal protection or Title IX is now much harder to win. But Washington has its own civil rights laws, and the Office of Superintendent of Public Instruction says those laws protect a student’s right to be treated consistently with their gender identity, KIRO 7 reports.

The new law and those protections now point in opposite directions. Sorting that out will fall to Washington’s courts, under Washington’s own law.

What happens next, and when

Initiative 638 takes effect on December 3, 2026, the WIAA told KATU. Until then, the association says, current state law governs, and championship events go ahead as planned. Its Executive Board will rewrite its handbook language to comply once the measure is law.

The ACLU of Washington called the result “a devastating blow” and said Initiative 638 “cements discrimination into law.” Its staff attorney Adrien Leavitt told KATU the organisation is exploring all potential next steps to uphold the rights of transgender girls. The state superintendent’s office says it will watch for the court filings it expects.

No lawsuit had been filed as of Thursday’s reporting. If one is, a court could pause Initiative 638 before December 3, or it could let the measure start while the case goes on. Nobody can tell a family tonight which of those will happen. What a family can do is prepare for both.

For parents of trans girls in Washington, that means a few practical steps:

• Write down what your child’s school and coach tell you about Initiative 638, with dates and names.
• Ask the school in writing who will receive any doctor’s statement, who may read it, and how long it will be kept.
• Keep copies of every form you hand in, and of every reply.
• Talk with your child’s own doctor before anyone else asks them for a statement.
• Watch the ACLU of Washington for word of a legal challenge before December 3.

Parents of every other girl on a team have questions of their own now, and the same written questions about privacy belong to them too.

What teammates, coaches and schools can do

Most of what decides whether Initiative 638 wounds a girl or merely inconveniences her will happen in locker rooms and school offices, not in court. A few things are within reach of almost everyone.

Teammates can refuse to turn this into gossip. Nobody owes a teammate an account of her paperwork, her body or her doctor’s visit, and nobody should ask. A girl whose statement is late is not a story. Speculating about who might be trans is exactly how a law aimed at ten students ends up hurting many more.

Coaches can treat every statement a player hands in as a medical record, because it is one. Keep it out of sight, out of conversation and out of group chats. Ask your district, in writing, for its process before December 3, and hold every girl to the same process so that nobody is singled out by the way she is handled.

Schools and districts can answer the questions families are already asking before the deadline arrives. Who collects the statements? Where are they kept, who may read them, and when are they destroyed? What happens to a girl whose family cannot get an appointment in time? Putting those answers in writing now is a kindness to every family on every girls’ team.

07

Oregon is not Washington

Bloom Ministries is based in Salem, so we get the question first from our own neighbours: does Initiative 638 change anything in Oregon? It does not. It is Washington law, and it stops at the Columbia River.

Oregon’s own rules point the other way. Legal Voice’s guide notes that the Oregon Equality Act protects against discrimination on the basis of gender identity, and that Oregon’s Department of Education tells schools not to exclude gender-expansive students from athletics aligned with their gender identity. The Supreme Court’s June decision did not require Oregon to change any of that.

The same guide notes that Oregon law recognises a student’s right to use restrooms and locker rooms consistent with their gender identity, and that gender-affirming care is protected under the Reproductive Health Equity Act of 2017 and House Bill 2002 of 2023. For a Washington family weighing its options, those are the protections that stand on this side of the river.

Legal Voice also notes that no Oregon initiative or referendum on this issue is pending. It adds that, after June, a future voter-approved ban here would be judged lawful under federal law. Washington’s vote is a reminder that a state’s protections are only as durable as the people who keep showing up for them.

08

The children at the centre of this

Strip away the campaign money and the polling, and Initiative 638 lands on about ten students. Ten kids who show up for practice and ride the bus home with their teammates like everyone else on the roster. They did not ask to become the subject of a statewide vote. Their existence is not a debate, and a law aimed at them does not make them any less who they are.

What a trans girl loses when she is told the team she loves is no longer hers is not a medal. It is the ordinary afternoon of belonging that every other kid on the bench takes for granted. That loss is real, and it deserves to be said out loud.

The other girls matter too. Initiative 638 asks every one of them to prove herself to a stranger before she is allowed to play. A law that guards girls’ sports by inspecting girls has misunderstood what it was guarding.
