  • requiring students seeking to participate in athletic activities designated for female students to submit documentation from their healthcare provider verifying the student’s sex, defined by certain biological factors.

A "no" vote opposes:

Overview

What would the initiative do?

See also: Text of measure

The ballot initiative would require school districts and nonprofit organizations that regulate interscholastic activities to "prohibit biologically male students from competing with and against female students" in sports with separate team or individual competitions for male and female students. The ballot initiative would require students seeking to participate in athletic activities designated for female students to submit documentation from their healthcare provider verifying the student’s biological sex based on "reproductive anatomy, genetic makeup, or normal endogenously produced testosterone levels."[1]

What do supporters and opponents say about the initiative?

See also: Support and Opposition

Speaking on behalf of Let's Go Washington, a Political Action Committee (PAC) that is leading the campaign in support of the initiative, Ahnaleigh Wilson and Frances Staudt said, "Biological men are competing in girls’ sports in Washington State, and it’s destroying fairness in girls’ sports. Title 9 created opportunities for women and girls to compete in sports, and those opportunities are being erased. As [two] female athletes who have been directly impacted by boys competing in girls’ sports, we are standing up for all 110,000 girls playing sports in Washington state middle and high schools. We’re too young to vote, but old enough to use our voice. We need moms, dads, grandparents, brothers and sisters to have the courage to stand up and protect fairness in girls’ sports.”[2]

No Hate in Washington State, an organization opposing the initiative, stated that, "It’s true some people have a difficult time understanding what it means to be transgender, and we all want fairness and safety in sports. Only a handful of transgender girls play afterschool sports in Washington, yet IL26-638 will rollback Washington’s successful sports policy in place since 2007 and institute a statewide blanket ban. This poorly written initiative will subject many girls to invasive, medically unnecessary and harmful genital exams to verify their sex."[3]

Background

Existing laws related to the administration of school sports

As of 2026, RCW 28A.600.200 grants each school district the authority to control, supervise, and regulate interschool athletic activities, and to delegate that authority to the Washington Interscholastic Activities Association or any other voluntary nonprofit entity.[12]

RCW 28A.640.020 grants the superintendent of public instruction the authority to develop regulations and guidelines to eliminate sex discrimination in certain public school structures, including recreational and athletic activities for students.[13]

Initiative No. IL26-638 would change the enforcement of chapters 28A.600.200 and 28A.640.020 of the Revised Code of Washington by requiring compliance with a new section that would prohibit biologically male students from competing with or against female students in athletic activities that have separate classifications for male and female students.[1]

Ballotpedia is tracking five ballot measures related to sports eligibility requirements based on sex.

Qualified

Two measures in Colorado and Washington that address transgender sports participation have qualified for statewide ballots in 2026.

State Type Title Description
CO

CISS

Sex Requirement for School and College Sports Initiative Require all K-12 and collegiate school sports teams to be separated based on biological sex, unless the team is co-ed
WA

IndISS

Sex Verification Requirements for Female School Sports Initiative Require school and voluntary nonprofit athletics to prohibit biologically male students from competing with and against biologically female students


Colorado Require Separate Teams Based on Biological Sex or Co-Ed Teams for School Sports Measure

The initiated state statute would require all K-12 and collegiate school sports teams to be separated based on biological sex, unless the team is co-ed. It was filed by Protect Kids Colorado. It was cleared for gathering signatures on August 25, 2025. The deadline to submit signatures was February 20.[14]

On March 16, 2026, the Colorado Secretary of State certified the initiative for the ballot.[15]

Support

Protect Kids Colorado's campaign website says, "Bigger, stronger biological males are invading girls' sports in Colorado, taking away our girls' dignity, safety, and opportunity. Our ballot measure ensures girls' sports are protected, requiring sports leagues and teams be specifically designated male, female, or co-ed. Because girls' sports in Colorado should be for girls. That's it."[16]

Opposition

Z Williams, co-director of the Denver nonprofit Bread and Roses Legal Center, said, "The number of trans athletes is incredibly small, and the number of gender-affirming surgeries done for transgender youth or minors is even smaller. We have two ballot measures … that are going to require hundreds of thousands of dollars, waste a lot of time, create a lot of confusion during the election over two pretty much manufactured issues.”[17]

Potential

Three ballot initiatives are in the process of qualifying for the ballot in Nevada, Maine, and Nebraska. All three measures would require sport participation based on sex, unless a team is co-ed.

State Type Title Description
ME

IndISS

Birth Certificate Sex Requirement for Public School Sports Initiative Require that public school sports teams designated for girls or boys be limited to students of the corresponding sex, as recorded on their birth certificate
NE

CICA

Sex Requirement for School and College Sports Amendment Require schools designate sports team as male, female, or co-ed and prohibit male participation on female sports teams
NV

CICA

Biological Sex Requirements for School Sports Programs Amendment Require that eligibility for sports or athletic competitions in public schools and colleges is based upon the biological sex of the athlete recorded at birth rather than gender identity or gender expression, and that biological males are not permitted to participate in a sport or competition designated for biological females


Maine Birth Certificate Sex Requirement for Public School Sports Initiative

The indirect initiated state statute would require that public school sports teams designated for girls or boys be limited to students of the corresponding sex, as recorded on their original birth certificate. The ballot initiative would also require public schools to maintain separate restrooms, locker rooms, shower rooms, and other private spaces for each sex. Schools would be required to designate athletic teams as male, female, or coeducational. Girls would be allowed to participate on male-designated teams when no female-designated team is available for that sport. The ballot initiative would allow students who are denied athletic opportunities or suffer direct injuries due to violations of the initiative to bring a civil action for injunctive relief, damages, and attorney’s fees against a school or the organization that governs interscholastic or competitive school sports.

Protect Girls Sports in Maine is sponsoring the initiative. The initiative was approved for signature gathering in November 2025. The campaign filed more than 82,000 signatures.

Support

Protect Girls' Sports in Maine said on its campaign website, "The truth is, males are currently in female sports, taking female trophies, and invading female safe spaces (like locker rooms and bathrooms). This is not a far away concept; it is happening right here in Maine. Concerned parents have brought these issues to their school boards, but the Maine Principal’ Association and State Legislature have failed to act. It’s now time that we – as citizens of this great state – decide for ourselves what we want for our kids."[22]

Opposition

Harry Burke, campaign manager for U.S. House candidate Matt Dunlap (D), said, "Mainers are worried about healthcare and the cost of living. This is a manufactured issue from Republicans. Paul LePage is only trying to distract from the fact that he cut healthcare for working class people so he could afford to give massive tax breaks to rich people.”[23]

Path to the ballot

Process in Washington

See also: Laws governing the initiative process in Washington

An indirect initiated state statute is a citizen-initiated ballot measure that amends state statute. There are nine (9) states that allow citizens to initiate indirect state statutes.

While a direct initiative is placed on the ballot once supporters file the required number of valid signatures, an indirect initiative is first presented to the state legislature. Legislators have a certain number of days, depending on the state, to adopt the initiative into law. Should legislators take no action or reject the initiative, the initiative is put on the ballot for voters to decide.

In Washington, the number of signatures required for an indirect initiated state statute, called an Initiative to the Legislature (ITL), is equal to 8% of the votes cast in the last gubernatorial election. Signatures for indirect initiatives are due at least 10 days prior to the beginning of the legislative session in the year of the targeted election.

In Washington, the Legislature has three options regarding Initiatives to the Legislature:

  • (1) The Legislature can adopt an Initiative to the Legislature, in which case the initiative is enacted into law without a vote of electors;
  • (2) The Legislature can reject or not act on the initiative, in which case the initiative is placed on the ballot at the next state general election; or
  • (3) The Legislature can approve an alternative to the proposed initiative, in which case both the original proposal and the legislative alternative are placed on the ballot at the next state general election.

If an indirect initiative goes to the ballot, a simple majority vote is required for approval.

The requirements to get an Initiative to the Legislature certified for the 2026 ballot:

Stages of this ballot initiative

  • March 12, 2026: The Washington State Legislature did not act on the ballot initiative before the legislative session ended, thereby certifying the initiative as-written for the ballot on November 3, 2026.

According to the U.S. Department of Justice, the application "may require only the minimum amount of information necessary to prevent duplicate voter registrations and permit State officials both to determine the eligibility of the applicant to vote and to administer the voting process."
