Schools are implementing Restorative Justice in Education (RJE) initiatives across the United States, often to reduce the use of out-of-school suspension, which is known to increase the risk for dropout and arrest. Many RJE initiatives also aim to strengthen social and emotional competencies, reduce gender and racial disparities in discipline, and increase access to equitable and supportive environments for students from marginalized groups. This policy brief summarizes research on restorative initiatives, with a focus on implementation and outcomes in U.S. schools. After examining the evidence, the authors offer recommendations for comprehensive RJE models and strategic implementation plans to drive more consistently positive outcomes.
