Preventing violence in and around school is a moral imperative. It is also essential to reap the benefits from education and ensure children’s well-being. Unfortunately, violence in schools remains widespread in Africa, as is the case in the rest of the world, contributing to learning poverty and leading some children to drop out of school. The objective of this paper is threefold. First, basic insights on the prevalence of violence in schools are provided. Second, some of the potential impacts of violence in schools are estimated. Third, a case is made to the effect that interventions to end violence in schools tend to have high benefit to cost ratios and are also affordable. In a nutshell, ending violence is not only the right thing to do, but also a smart investment to invest in children’s human capital.
