The Colorado Sex Requirement for School and College Sports Initiative is on the ballot in Colorado as an initiated state statute on November 3, 2026.

A "yes" vote supports requiring student athletes to participate on men's or women's school and collegiate athletic teams that match their sex, defined as biological reproductive systems.

A "no" vote opposes requiring student athletes to participate on men's or women's school and collegiate athletic teams that match their sex, defined as biological reproductive systems.

Overview

What would Initiative 109 do?

See also: Text of measure

The ballot initiative, Initiative 109, would require school- and association-sponsored athletic teams to be classified in one of three categories based on biological sex: (1) males/men/boys, (2) females/women/girls, or (3) coeducational or mixed. Teams designated for females, women, or girls would not be open to male students or participants. Teams designated for males, men, or boys would not be open to female students or participants unless no corresponding female team is offered for that sport. The measure would not limit participation in teams designated as coeducational or mixed.

The ballot initiative would define females as "person[s] whose biological reproductive system is organized around the production of ova," and males as "person[s] whose biological reproductive system is organized around the production of sperm."

Each school’s governing body would be required to adopt a policy implementing the measure.

What do supporters and opponents say about Initiative 109?

See also: Support and Opposition

Protect Kids Colorado, the organization leading the campaign in support of Initiative 109, said, "It's not fair – It's not safe. 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."

Nadine Bridges, executive director of One Colorado, which is leading the Families Not Politics campaign against Initiative 109, said, "[Initiative 109] is vague, poorly written, and leave[s] critical questions unanswered. Who decides who gets questioned, who gets inspected, and which kids are going to be singled out? When laws are written this vaguely, they open the door to unintended consequences that can cause serious harm to all of our kids."

What are the current laws about gender identity in Colorado?

See also: Background

On May 20, 2021, Gov. Jared Polis signed the Gender Identity Expression Anti-discrimination Act (HB21-1108), which amended section 24-34-601 of the Colorado Revised Statutes to include gender identity and gender expression as protected classes in places of public accommodation.

According to section 24-34-600.3, educational institutions and sporting or recreational areas and facilities are included as examples in the definition of a place of public accommodation.

Text of measure

Ballot title

The ballot title for the initiative is as follows:

“

Shall there be a change to the Colorado Revised Statutes creating new law restricting participation in all K-12 and collegiate school sports based on the participant’s sex as determined by certain aspects of their biological reproductive system, and, in connection therewith, requiring a school, institution of higher education, or athletic association to designate each school or intramural athletic team or sport as male, female, or coeducational; only allowing participants to compete on the team or sport of their designated sex or to compete on a coeducational team; creating an exception to allow a female to participate on a male-designated team or sport if there is no female team available; prohibiting a government entity, licensing or accrediting organization, or athletic association from entertaining a complaint, opening an investigation, or taking other adverse action against a school for maintaining separate teams or sports for females; and providing the commissioner of education with the authority to enforce the proposed initiative for K-12 school districts?

Support

Protect Kids Colorado is leading the campaign in support of the ballot initiative. Additionally, the organization is leading the campaign in support of Initiative 108 and Initiative 110.

Supporters

Organizations

• Colorado Catholic Conference
• Focus on the Family

Arguments

• Colleen Enos, Christian Home Educators of Colorado: "To allow males to compete against females when they are physically advantaged in muscle mass, bone density, and muscle capacity makes a mockery out of Title IX protections for girls."
• Protect Kids Colorado: "It's not fair – It's not safe. 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."
• Colorado Catholic Conference: "School and athletic organization policies that undermine the biological reality of a person's body as male or female deny human dignity and are abusive to minors. Policies that allow biological men to participate in women's sports promote the unfair treatment of women and pose potentially dangerous and inappropriate situations for young women, including sharing bathrooms and locker rooms with biological men."

Opposition

Families Not Politics is leading the campaign in opposition to the ballot initiative. Additionally, the organization is leading the campaign in opposition to Initiative 110.

Opponents

Organizations

• Inside Out Youth Services
• Interfaith Alliance
• One Colorado
• Planned Parenthood of the Rocky Mountains
• Rocky Mountain Equality

Arguments

• Rocky Mountain Equality: "This initiative would prohibit transgender youth of any age from playing sports with their peers. It singles out one small group of students and keeps them from participating in the same school activities as all other students."
• Z Williams, co-director of Bread and Roses Legal Center: "This ballot measure is basically taking a non-issue — there are not that many children who are trans, and there are not that many people who are trans who are athletes — and is using it as a flashpoint for organizations who are very concerned, and I think rightfully so, that their ideology is dwindling. ... They're organizations that are interested in protecting very few kids and, like I said, their efforts are going to open up increased scrutiny of all girls and make all girls now the target of investigation about their gender arrangement, about their biology."
• Nadine Bridges, executive director of One Colorado: "[Initiative 109] is vague, poorly written, and leave[s] critical questions unanswered. Who decides who gets questioned, who gets inspected, and which kids are going to be singled out? When laws are written this vaguely, they open the door to unintended consequences that can cause serious harm to all of our kids."

Background

Recent developments of sports eligibility requirements based on sex in Colorado

Gender Identity Expression Anti-discrimination Act (2021)

On May 20, 2021, Gov. Jared Polis signed the Gender Identity Expression Anti-discrimination Act (HB21-1108), which amended section 24-34-601 of the Colorado Revised Statutes to include gender identity and gender expression as protected classes in places of public accommodation.

According to section 24-34-600.3, educational institutions and sporting or recreational areas and facilities are included as examples in the definition of a place of public accommodation.

Executive Order 14201

See also: Executive Order: Keeping Men Out of Women’s Sports (Donald Trump, 2025)

On February 5, 2025, President Donald Trump (R) signed an executive order stating that it is the "policy of the United States to oppose male competitive participation in women’s sports more broadly, as a matter of safety, fairness, dignity, and truth." The executive order defined male and female as they are written in Executive Order 14168.

On May 8, 2025, Colorado Springs School District 49 passed a resolution by a 3-2 vote to establish sex requirements for school sports teams in accordance with Executive Order 14201. On May 9, 2025, the school district filed a lawsuit, School District 49 v. Sullivan, against the Colorado High School Activities Association (CHSAA) and state officials to determine if the policy was legal. Peter Hilts, superintendent of the school district, said, "Rather than being a recipient of potential penalties or legal action, we filed a lawsuit as a pre-enforcement action to make certain that we can protect opportunities for girls, protect privacy for girls and boys, and make sure we are shielding the district from any legal liability."

On December 4, 2025, the CHSAA reached a settlement with District 49 and continued with the other defendants, including Attorney General Phil Weiser and the Colorado Civil Rights Division.

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.

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

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."

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.”

Washington Limit Participation in Female Sports to Students Verified as Biologically Female Initiative

The initiative to the Legislature would require schools and voluntary nonprofit athletics to prohibit biologically male students from competing with and against biologically female students in an athletic competition if the activity has separate classifications for male and female students. These requirements would apply to individual and team competitions. The initiative would require that a student athlete's biological sex be verified by their health care provider, "relying only on one or more of the following: The student's reproductive anatomy, genetic makeup, or normal endogenously produced testosterone levels."

Let's Go Washington is leading the campaign in support of the ballot initiative. It was filed and cleared for signature gathering in June 2025. The campaign submitted 445,187 signatures on January 2, 2026. On January 22, the secretary of state announced the petition met the signature requirement and certified it to the legislature.

The Washington State Legislature did not act on the ballot initiative before the legislative session ended on March 13, 2026, certifying the initiative for the ballot.

Support

Ahnaleigh Wilson and Frances Staudt, two high school athletes in Washington, 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."

Opposition

Washington Families for Freedom, the campaign registered in opposition to the initiative, said, "[T]his poorly designed initiative ultimately could put some girls at greater risk by subjecting them to invasive genital exams just to play on an after-school team. We should not impose a blanket ban that eliminates case-by-case solutions and distracts from affordability, housing, and other real problems facing Washingtonians."

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

Nebraska

Nevada

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."

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.”

Nebraska Sex Requirement for School and College Sports Amendment (2026)

The initiated constitutional amendment would require schools to designate sports teams as male, female, or co-ed. Teams designated as female would prohibit male sex students from participating. The amendment would apply to all public schools and college teams and any private-run school that competes against public schools or colleges. The amendment would also authorize the Nebraska State Legislature to pass laws to facilitate the amendment's operation.

Robert M. Shafer, Julie Slama, and Elizabeth Nunnally filed the initiative on February 26, 2026.

Support

Fairness for Girls, the campaign behind the initiative, said, "Nebraskans support preserving opportunities for young girls, protecting female athletes’ safety, and keeping the process fair. Biological males competing in girls’ sports pose a physical safety risk to young girls while also taking away opportunities for medals, tournament advancement and scholarships."

Opposition

Rainbow Parents of Nebraska said, "Trans people make up less than 1% of our state’s population. Trans athletes are an even smaller percentage of that 1%. This does NOT protect women as they like to claim. This is another distraction and an attempt to increase conservative voter turnout."

Nevada Biological Sex Requirements for School Sports Programs Amendment

The initiated constitutional amendment would 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. Biological females may participate in a sport designated for biological males if there is no comparable sport or competition offered for biological females.

Protect Girls' Sports PAC filed the initiative in January 2026.

In Nevada, initiated constitutional amendments must be approved at two consecutive statewide general elections, which means if the initiative makes the 2026 ballot, it would also need to be approved in 2028.

Support

• Nevada Gov. Joe Lombardo (R), who is sponsoring the Nevada initiative, said, "We are taking thoughtful steps to ensure girls’ sports are fair and athletes are safe."

• Adriana Guzmán Fralick, one of the directors of the initiative, said, "Title IX was instituted for a reason – to create a level playing field so that girls and boys have an equal chance to succeed in our schools. But there has been an attack on girls’ athletics that seeks to disrupt that equality. The people of Nevada do not support this, and I’m proud to help them make their voice heard on this issue at the ballot box."

Opposition

• Silver State Equality, which describes itself as Nevada’s statewide LGBTQ+ civil rights organization, said, "We all want sports to be fair and student athletes to be safe. That’s why school districts and sports associations already make rules about who can participate in different sports at different levels. A blanket statewide ban overriding these rules would be bad for everyone, requiring young girls to answer invasive personal questions or even undergo physical inspections by strangers if they want to play sports."

• Washoe County Commission Chair Alexis Hill, who is running as a Democrat gubernatorial candidate in Nevada, said, "I think that this is all about politics to drive Republican turnout and it’s unacceptable and really a nonissue in Nevada."

Path to the ballot

The state process

An initiated state statute is a citizen-initiated ballot measure that amends state statute. There are 21 states that allow citizens to initiate state statutes, including 14 that provide for direct initiatives and nine (9) that provide for indirect initiatives (two provide for both). An indirect initiated state statute goes to the legislature after a successful signature drive. The legislatures in these states have the option of approving the initiative itself, rather than the initiative appearing on the ballot.

In Colorado, the number of signatures required for an initiated state statute is equal to 5% of the votes cast for the Colorado secretary of state in the preceding general election. A simple majority vote is required for voter approval. The requirements to get an initiated state statute certified for the 2026 ballot:

• Signatures: 124,238 valid signatures are required.
• Deadline: The deadline to submit signatures is August 3, 2026.

Details about this initiative

• July 25, 2025: The initiative was filed by Erin Lee and Michele Austin.
• August 25, 2025: The initiative was cleared for signature gathering with signatures due by February 20, 2026.
• February 20, 2026: The campaign supporting the initiative, Protect Kids Colorado, reported submitting over 164,000 signatures to the Colorado secretary of state for review.
• March 16, 2026: Secretary of State Jena Griswold (D) announced that a 5% random sample of the submitted signatures projected that the petition contained more than 110% of the number of valid signatures required, thereby qualifying for the ballot.

Colorado does not require proof of citizenship for voter registration. An individual applying to register to vote must attest that they are a U.S. citizen under penalty of perjury.

All 49 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment. Eight states — Alabama, Arizona, Kansas, Louisiana, New Hampshire, South Dakota, Utah, and Wyoming — have laws requiring individuals provide proof of citizenship at the time of voter registration, whether in effect or not. Three states, Florida, Georgia and Mississippi, require a person provide proof of citizenship if their citizenship status cannot be verified by other means. One state, Ohio, requires proof of citizenship only when registering to vote at a Bureau of Motor Vehicles facility. In three states — California, Maryland, and Vermont — at least one local jurisdiction allows noncitizens to vote in some local elections. Noncitizens registering to vote in those elections must complete a voter registration application provided by the local jurisdiction and are not eligible to register as state or federal voters.
