With a growing evidence-base for interventions like Shifting Boundaries that focus on improving school environments to prevent teen dating violence and sexual violence, practitioners are increasingly implementing efforts that combine classroom lessons along with school-wide changes. The Shifting Boundaries curriculum is an evidence-based, multi-level program for middle school students to prevent sexual harassment and precursors to dating violence. The program is unique in that it embraces an environmental approach that identifies multiple strategies to support young people. As part of the Rape Prevention and Education Program, the California Department of Public Health (CDPH) is implementing Shifting Boundaries with two local partners: Safequest Solano (in Fairfield) and Center for Non Violent Community (in Sonora). Together the state and local partners are working to comprehensively improve school climate and build environments that support safety for students and school staff. This has involved gaining school buy-in, implementing the curriculum and acting on recommendations for school-wide changes.
