Discussions about school violence rarely include public health's proven prevention approaches. Public health approaches focus on preventing violence before it starts and have been shown to effectively reduce school and youth violence. This known effectiveness stands in contrast to commonly used prevention strategies, such as metal detectors and other security measures, for which there is insufficient data to determine their benefits and some evidence to suggest that they may negatively impact students’ perceptions of safety.1 Public health offers knowledge and experience in preventing school violence that can significantly enhance approaches to end school violence.
