Inclusive and equitable quality education provides all learners with the capabilities to become economically productive, develop sustainable livelihoods, contribute to peaceful and democratic societies, and enhance individual wellbeing. This technical brief describes why school leadership matters for quality education and the evidence-based approach VVOB takes to introducing and embedding school leadership in developing countries. The experiences of VVOB show the value of identifying an appropriate entry point, working with governmental agencies responsible for training educators, demonstrating the ‘what, who and how’ of school leadership through pilot programmes, and institutionalising school leadership in the education system. As described in the case study of VVOB work in Rwanda, developing and embedding school leadership requires long-term commitment and solid partnerships.
