The study is a pilot randomized control trial implemented by Raising Voices, LSHTM & AfriChild Centre. The overall aim of this pilot trial is to determine whether progression to a phase 3 cluster randomized controlled trial to deliver the Good School Toolkit-Secondary Schools intervention to prevent violence in Kampala/Wakiso District, Uganda, is justified in terms of pre-specified acceptability and feasibility criteria. Through our ongoing qualitative analysis, we are witnessing a reduction in incidents of violence in secondary schools partly because of the penetration of good school ideas to students, teachers, and their parents. Though we report a general reduction in violence cases, a new face of violence is now evident- we see more incidents of peer violence in secondary schools.
