The WITS Programs aim to reduce peer victimization through a comprehensive, community-based approach. Two evaluations found that rates of physical and relational victimization declined more in schools implementing WITS compared to control schools. While initial victimization reports were higher in WITS schools, possibly due to increased awareness, peer support did not differ between groups. Teachers rated children in WITS schools as having higher social responsibility at each time point. Overall, WITS was found to effectively reduce peer victimization through involving community champions and consistently teaching peaceful conflict resolution across settings.
