This guidance provides education policymakers across England and Wales with eight recommendations on how to prevent children’s involvement in violence. The guidance report draws on the best available global evidence on how to prevent children’s involvement in violence. The guidance also incorporates primary research conducted by the Youth Endowment Fund (YEF), including evaluations of violence prevention programmes and large-scale surveys involving 10,000 teenage children and 9,500 teachers. The YEF also commissioned three reviews of practice and policy to inform the specific recommendations in this report. A consultative group of headteachers, academics and policy experts from across England and Wales has guided the development of this guidance, applying their knowledge of practice and policy to ensure the recommendations are feasible.
