The European Toolkit for school success presents concrete ideas for improving collaboration within, between, and beyond schools, aiming to enable all children and young people to succeed in school. School leaders, teachers, parents, and others involved in different aspects of school life can find helpful information, examples of measures taken, and resource materials to inspire their efforts to provide effective, high-quality early childhood and school education. The aim of the Toolkit is to support exchange and experience among school practitioners and policy makers.
