Positive youth development highlights the promotion of skills through engaging and caring settings and building opportunities for bidirectional and constructive relationships. Whole School Restorative Approaches (WSRA) promote school community relationships and social and emotional skills which are core components for positive youth development. To our knowledge, the literature reviews on the implementation of restorative practice approaches in schools do not focus specifically on WSRA and are not comprehensive. This study carries out a systematic review of the empirical evidence on the effectiveness of WSRA and develops some evidence-based practice guidelines on their effects. Thirteen studies met the inclusion criteria and we developed 10 evidence-based practice guidelines on the implementation of WSRA. There were many studies with WSRA showing positive results related to improving social and emotional skills and behavior. The highest level of scientific evidence is for secondary education where two WSRA are recommended. Although our review suggests that more rigorous methodological research is necessary, it also points out that the evidence available on WSRA implementation is encouraging. They could be used through all educational stages to deal with diversity and inclusion while promoting a school culture of peace based on the positive management of relationships and conflicts.
