As countries strive to reform education systems and improve student results, school leadership is high on education policy agendas. But in many countries, the men and women who run schools are overburdened, underpaid and near retirement. And few people are lining up for their jobs. Based on an OECD study of school leadership practices and policies around the world, and offering a unique cross country perspective, this book identifies four policy levers and a range of policy options to help governments improve school leadership now and build sustainable leadership for the future.
