Purpose: The purpose of this paper is to identify best practices in the implementation of school-based sexual violence prevention education. Design/methodology/approach: A three-phase plan was implemented to evaluate the Sexual Harassment/Assault Prevention Project (SHAPP) in one state in the USA. First, a structured review of the prevention curricula of the participating communities was completed. Second, a survey of school personnel on best practices and challenges associated with their initiative was conducted. Third, school staff school climate surveys were administered, focus groups with teachers, students, and parents were conducted, and behavioral incident records were reviewed in two middle schools, one implementing SHAPP, and the other with no programming for sexual violence prevention. Findings: Compared to the school with no programming, in the SHAPP school, staff reported better school climate and safety, and student participants reported more positive opinions about their school's prevention efforts. Practical implications: The implementation of sexual harassment/sexual assault and bullying prevention programs may result in a more positive school climate, an increased sense of safety among students and staff, and a decrease in incidents of sexual harassment/assault and bullying. Originality/value: The study suggested that building sexual harassment and assault prevention efforts from the platform of a school-wide, evidence based, bullying prevention strategy offers many advantages.
