The ‘What Works to Prevent Violence - Impact at Scale’ Programme is a seven-year initiative funded by the UK’s Foreign, Commonwealth and Development Office on prevention of violence against women and girls, focused on learning about how to take small-scale evidence-based approaches to scale. Extensive evidence shows that violence in and around schools can have significant impacts on educational outcomes, both directly and indirectly. Directly, violence in and around schools can impact the academic performance of learners, increase the risk of absenteeism and dropout rates, and negatively impact future careers and earning potential. Indirectly, violence in and around schools can have long-lasting negative impacts on brain development, mental health, social-emotional skills, and continues to perpetuate the cycle of violence. All direct and indirect impacts on educational outcomes are mutually reinforcing of each other and can be a cause and effect of one another. Gender inequality is a root cause of violence in schools. Gender inequality, discriminatory practices, and harmful norms that position women and girls as “subservient”, drive violence against them. Addressing gender inequality and promoting more gender equitable culture in schools is key to preventing violence. There is extensive evidence on the prevention of violence that highlights violence in and around schools is preventable. Schools and governments that are tackling or have tackled this issue have seen reductions in school dropouts and improved educational outcomes. Most interventions cover five thematic areas: building life skills; building knowledge and awareness; providing psycho-social support; providing skills training for the school staff; and promoting a whole-school approach.
