This article reports on the findings from a study into high-performing leadership teams in English primary schools. The schools, in the sample, received "outstanding" Office for Standards in Education (Ofsted) grades overall, and for leadership and management, in their most recent school inspection. The evidence suggests that developing a successful primary school leadership team takes time, commitment and continuity. The development of leaders requires a deliberate approach to build individual capacity and team unity. Effective team working takes time to develop and that "quick fix" solutions to inadequate team work are inappropriate.
