In the past decade, several states have introduced comprehensive sexuality education standards for public schools, but the impact is unknown because mechanisms to monitor adherence and improve quality have been lacking. In this study, we pilot-tested an approach for high school students to assess sexuality education standards mandated by the California Healthy Youth Act. We introduced a 15-minute online survey administered at the conclusion of sexuality education instruction. Results from thirteen Los Angeles high schools indicated that the approach was acceptable, feasible, and valid. It provided actionable data about which standards were being followed and whether the classroom environment was conducive to learning.
