Reducing violence and aggression in schools.

This article offers a framework for understanding and responding to school-based aggression and violence. The term school violence is defined, epidemiological data are summarized, a typology of violence reduction strategies is presented, and procedures to effectively implement evidence-based programs are discussed. Although many evidence-based violence prevention programs are now available to schools, much work remains in three critical areas. First, additional research is needed to evaluate the impact of security strategies, peer-led programs, and threat assessment and crisis response initiatives. More generally, multi-level evaluations of integrated arrays of school-based violence prevention strategies need to be undertaken. Second, effective and realistic school-based assessment strategies need to be established to identify and address organizational barriers to the selection and adoption of an integrated and comprehensive array of targeted evidence-based violence prevention strategies in schools. And third, realistic guidelines through which schools can effectively monitor and implement evidence-based programs need to be developed.
