Colorado voters have approved Proposition 134, a new amendment to the Colorado Revised Statutes that sets clear standards for participation in school and college athletics. The measure, which received a majority of votes in the recent election, requires each athletic team or sport to be designated as male, female, or co‑educational. Participants may only compete on the team that corresponds to their biological reproductive system, as defined by the statute.

Key Provisions of the Initiative

The law establishes several specific requirements:

• Every K‑12 school, institution of higher education, and athletic association must label each team or sport as male, female, or co‑educational.
• Students are permitted to compete only on the team that matches their designated sex, unless the team is co‑educational.
• An exception allows a female student to join a male‑designated team when no female team is available for that sport.
• Government entities, licensing or accrediting organizations, and athletic associations are prohibited from filing complaints, opening investigations, or taking adverse action against schools that maintain separate male and female teams.
• The Commissioner of Education is granted authority to enforce the new requirements for K‑12 districts.

Supporters Cite Fairness and Safety

Proponents of Proposition 134 argue that the measure protects the integrity of women’s sports by ensuring competition is based on biological differences that affect physical performance. They contend that the legislation upholds parental rights to choose an environment consistent with their family’s values and supports traditional family structures by preserving separate opportunities for boys and girls.

Opposition and Concerns

Critics, including several civil‑rights groups, have expressed concern that the law could discriminate against transgender and non‑binary students, limiting their ability to participate in sports that align with their gender identity. They argue that the statute may conflict with existing federal protections and could expose schools to legal challenges.

Implementation Timeline

The Colorado Department of Education will develop guidance for schools and colleges to comply with the new requirements. The Commissioner of Education is expected to issue enforcement protocols within the next few months, giving districts time to adjust team designations and update policies before the start of the 2027‑2028 academic year.

What This Means for Colorado Families

For parents and students, the passage of Proposition 134 means that school athletic programs will now be organized strictly by biological sex, with limited pathways for female athletes to join male teams when necessary. Families who value traditional gender distinctions in sports may view the measure as a reinforcement of those principles, while others may need to navigate new eligibility rules for their children.

Stakeholders are encouraged to review the upcoming Department of Education guidelines and to participate in any public comment periods that may be offered as the state finalizes enforcement details.
