This guide provides lessons learned from the Center’s Restorative Justice in Schools Project. Over the course of three years, our team worked in five high schools implementing restorative practices. The theory of change was simple: strong relationships create safer and healthier school environments. The aim of the guide is to assist educators, students, and community members in shifting their schools away from punitive approaches and towards a more restorative environment, and to lay the foundation for the entire school community to build positive connections.
