Colorado’s Sex Education Snapshot

The State of Sex Education 

Advocates have worked diligently to advance sex education in Colorado over the past seven years, most recently cumulating in the monumental passage of House Bill 1032 in 2019. Sponsored by Representative Susan Lontine, House Bill 1032 requires sex education, if offered, to be comprehensive, prohibits emphasizing abstinence as the primary acceptable preventive method, ensures all pregnancy options, including abortion are taught, and prevents instruction from using stigmatizing or shame-based language.

The passage of House Bill 1032 came six years after a revision of the previous sex education statute that updated the original 2007 law and ensures that curriculum is age-appropriate, medically accurate, and culturally sensitive to young people of color, LGBT youth, young people with disabilities, and young people who have experienced sexual assault.

In addition to this revised regulation, organizations such as the Colorado Sexual Health Initiative provide comprehensive sex education programming and have grants available to support counties in developing such programs. Advancements have also been made outside of curriculum requirements, such as with Senate Bill 21-016, introduced by Senator Brittany Pettersen and enacted on July 6, 2021. This bill expands young people’s access to health care by permitting minors to consent to the prescription of medication to treat sexually transmitted infections (STIs).

Since Colorado schools are not required to provide sex education to students, school districts are left to decide if they will provide youth with comprehensive sex education. Local control over sex education presents unique challenges that have resulted in a glaring disparity regarding the quality of sex education that students receive. Prior to the passage of House Bill 1032, students reported receiving abstinence-only instruction that utilized shame-based tactics, including equating students who have had sex to pieces of tape that have lost their stickiness. Other students reported that the curriculum failed to include instruction on consent.

While state statute mandates all schools comply with the new requirements, some schools, including the Liberty Common School in Fort Collins, have applied for a waiver to avoid implementing the new, comprehensive instruction. If successful, schools who are permitted to waive the new requirements may continue teaching abstinence-based curriculum that fails to provide young people with a comprehensive approach to ensuring their own reproductive and sexual health and well-being.

Right now, advocates can take action to ensure young people in their community have access to quality sex education. After contacting their local school board, advocates can determine if young people are receiving sex education and, if so, ensure that it complies with the new mandated requirements. They can then vocalize the important need for advancing sex education requirements in their community by complying with the new state mandates. Advocates are encouraged to take action on pending legislation that seeks to advance or restrict the principles of comprehensive sex education. For a current overview of pending legislation, see table below. Additionally, reach out to EducateUs to get connected to local advocacy groups. Further, advocates can contact their representatives to discuss the critical need for increased funding to support schools in implementing comprehensive sex education. Advocates are encouraged to use the SIECUS Community Action Toolkit to guide local efforts.

State Law

Colorado state law does not require schools to provide sex or HIV instruction; however, it refers to “medically and scientifically accurate information” as a “right” of youth in Colorado statute §22-1-128. Statute mandates that all school districts that offer human sexuality instruction must provide comprehensive sex education. Curricula must include medically accurate, culturally sensitive information about methods to prevent unintended pregnancy and sexually transmitted infections (STIs), including HIV/AIDS, and must include information about abstinence, all FDA approved forms of contraception, and be taught in a “cohesive, integrated, objective manner” so that youth are empowered to make decisions based on their “individual needs, beliefs, and values.”

Additional requirements state that the instruction must promote the development of healthy relationships through providing instruction on:

  1. How to communicate consent, recognize the withdrawal of consent, and understand the age of consent
  2. How to avoid making unwanted sexual advances or assuming a person’s supposed sexual intentions based on a person’s appearance or sexual history
  3. Age appropriate information on “Safe Haven Laws” relating to the safe abandonment of newborn children
  4. All pregnancy outcomes, including abortion, if the school district opts to provide instruction on pregnancy outcome options

In addition, sex education instruction must not:

  1. Explicitly or implicitly teach or endorse religious ideology
  2. Use shame-based or stigmatizing language or instructional tools
  3. Emphasize abstinence as the primary or sole preventative method
  4. Rely on gender stereotypes
  5. Exclude the health needs of intersex individuals or LGBT individuals

Parents or guardians must be notified if a sex education course is taught, and they must be given an opportunity to review the curriculum. They may remove their children from sex education or STI/HIV education classes by sending written notice to the school. This is referred to as an “opt-out” policy.

Per Colorado statute §22-25-104, the Colorado Department of Education is responsible for providing guidelines as to the length of courses, the subjects included, and the manner in which these subjects are addressed.

In 2013, the state legislature established a grant program for comprehensive human sex education, via Colorado statute §25-44-102. Schools that accept this funding must use curricula that are age appropriate, culturally relevant, medically accurate, and are based in science. In 2019, the state legislature amended the statute to ensure that the grant program’s oversight entity is made up of a diverse population of community members. The amendment also instructed that rural public schools and schools that do not currently offer comprehensive sex education take priority during the grant recipient selection process.

State Standards

The Department of Education provides guidelines on curriculum development through the Colorado Academic Standards: Comprehensive Health Standards. Sexual health topics—including HIV and other STD transmission and prevention, unintended pregnancy, abstinence, and sexual assault—are components of these standards.

State Legislative Activity

State legislative activity related to sex education does not take place in isolation from the broader embroiled political and policy climate. Attacks on the rights of lesbian, gay, bisexual, transgender, queer, or questioning (LGBTQ) individuals, attempts to restrict or prohibit instruction on “divisive concepts” such as Critical Race Theory, and efforts to limit access to abortion care and other reproductive health care services prevent students from receiving comprehensive sex education and accessing sexual and reproductive health care services. Below are highlights of current legislative activity related to these topics.

Youth Sexual Health Data

Young people are more than their health behaviors and outcomes. While data can be a powerful tool to demonstrate the sex education and sexual health care needs of young people, it is important to be mindful that these behaviors and outcomes are impacted by systemic inequities present in our society that affect an individual’s sexual health and well-being. To learn more about Colorado’s Youth Risk Behavior Survey (YRBS) results, click here.

Colorado School Health Profiles Data 

In 2019, the Centers for Disease Control and Prevention (CDC) released the School Health Profiles, which measure school health policies and practices and highlight which health topics were taught in schools across the country. Since the data were collected from self-administered questionnaires completed by schools’ principals and lead health education teachers, the CDC notes that one limitation of the School Health Profiles is bias toward the reporting of more positive policies and practices. In the School Health Profiles, the CDC identifies 20 sexual health education topics as critical for ensuring a young person’s sexual health. Colorado did not participate in the 2016 or 2018 survey.

(Visit the CDC’s School Health Profiles report for additional information on school health policies and practices.)
