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. The authors present the accumulating evidence that restorative approaches can reduce the use of exclusionary discipline. They describe promising evidence that such approaches can narrow racial disparities in discipline. They consider the mixed findings related to improving school climate and student development in light of possibly faulty models and mis-implementation of RJE. Finally, the authors offer recommendations for comprehensive RJE models and strategic implementation plans that they believe will result in more consistent positive outcomes.
