Restorative justice (RJ) is an alternative approach to school discipline that has been gaining recognition in the public and academic spheres as a way to engage students who misbehave in school. RJ has promise to address racial/ethnic, gender, and disability disproportionality in school discipline. One aspect of school-based RJ that has received almost no attention in the literature is the professional development and ongoing support of teachers in schools using RJ. This article provides a review of extant literature on school-based RJ, teacher training, and consultation methods. Integrating the empirical literature on school consultation and teacher professional development, we argue that schools should implement a multitiered model of professional development to build teacher competency in RJ, specifically including the use of targeted teacher consultation. The proposed model is complementary to an RJ framework, systematic, and capable of evaluation; future research is needed to evaluate its effectiveness in practice.
