This systematic review used framework synthesis methodology to explore literature describing problem-solving, circle and consultation groups in schools (PSGs). The review sought to understand the underlying mechanisms which contribute to the reported success of these groups. Key themes contributing to positive outcomes associated with these groups were identified. Environment, preparation and planning, and group structure enabled subsequent psycho-social processes in the group; examples being a sense of safety, learning, emotional containment, and belonging. Group participation was related to wider positive impacts in the classroom and school environment. The intervention was deemed to be socially valid by participants. This paper contributes to the understanding of group approaches to problem-solving in education. It discusses benefits for staff, pupils and education settings. The paper further offers a description of an ideal set-up for such groups to support staff working in schools.
