How U.S. Schools Teach Sex Education—and Why Parents Are Still the Key

In the United States, the way children learn about sex and puberty varies dramatically depending on whether they attend public school, private school, or are homeschooled. But despite differences in approach, research consistently shows that parents ultimately have the greatest influence on their children’s understanding of sexual health.

1. Sex Education in Public Schools: A Patchwork

• Nearly all public students receive some sex education between grades 7–12, with some topics starting in grades 5 or 6—but the quality and content vary widely by district and state 

• Only 39 states plus Washington, D.C. require some form of sex or HIV education, and only 18 states legally require that it be medically accurate 

• Fewer than half of high schools—and under a fifth of middle schools—cover all 20 CDC‑recommended topics, which include consent, contraception, and gender identity 

• In more conservative states like Mississippi, abstinence is often prioritized, condom demonstrations are banned, and sex education remains minimal—contributing to higher rates of teen pregnancy and STIs

2. Private Schools & Homeschooling: A Mixed Bag

• Private schools often follow religious or values-based curricula that emphasize abstinence and may omit medically accurate content about contraception, gender identity, or sexual orientation.

• Homeschooling families vary widely based on personal beliefs—some teach comprehensive sex ed at home, others avoid the topic. But without external oversight, gaps often develop if parents aren’t equipped or prepared to cover the full range of topics.

3. Why Parents Matter Most

• A majority of teens—around 70%—report getting most of their sexual information from their parents, making caregivers a more influential source than school, friends, or media 

• Research shows that parent-led communication about sex and relationships leads to important outcomes: delayed sexual initiation, fewer sexual partners, higher contraceptive use, and reduced risk of STIs and early pregnancy

• Meta-analyses confirm that programs involving parents significantly improve parent‑teen communication and safer sexual behavior 

4. Parental Attitudes & Support for Sex Ed in Schools

• More than 93% of parents believe sex education is important in both middle and high school; even across political affiliations, 78–89% support including topics like puberty, STDs, birth control, and relationships

• Interestingly, parents who oppose school-based sex ed are least likely to talk about these topics at home, despite believing it should only happen there 

5. What This Means for You as a Parent

• School-based sex ed—especially in public or private systems—is inconsistent and often falls short on medically accurate, values-aligned content.

• Even when schools cover some topics, many teens report receiving misinformation or insufficient depth.

• But when parents take the lead—using proper language, honest answers, and ongoing conversations—they fill the gaps, and kids respond with increased confidence, safety, and clarity.
