This article takes restorative justice as an example of an initiative that crosses disciplinary boundaries, and that has been usefully applied within educational contexts. Grounded in criminology, restorative justice also has roots in psychology, education, sociology, peace studies, philosophy and law. The article draws on an ESRC funded seminar series which investigated interdisciplinary perspectives on restorative justice and their applicability to education. The series found that the ways in which restorative justice is conceptualised and applied varies according to disciplinary norms and assumptions. It is this creative tension that the current article explores.
