This study examined the prevalence of student-to-student and staff-to-student sexual harassment in K-12 schools and school district compliance with Title IX using a retrospective survey of young adults. Participants (n = 511) were asked to describe their knowledge of policies and procedures regarding Title IX, the prevalence of sexual harassment, and the school's observed response to harassment using a 34-item, anonymous online survey. Descriptive statistics revealed that 13.4% of participants perceived that sexual harassment at their K-12 school district was at a "moderate" or "high" level, 50.1% reported that they either knew someone who experienced sexual harassment by a school employee or experienced it themselves, and 17.4% (n = 89) of individuals personally experienced one or more incident of staff-to-student sexual harassment. Nearly all (94%) students were unable to identify their Title IX compliance officer and 70% were unaware of how to file grievances. School districts without policies and materials that address sexual harassment had statistically significantly higher rates of harassment than school districts with policies (p = 0.01) and materials (p < 0.01).
