This article reports on an empirical study of the management of curriculum and instruction in South African secondary schools. Drawing on data collected from 200 schools in 2007, a series of regression analyses tested the relationship between various dimensions of leadership and student achievement gains over time. Whilst the research confirms what we do know about school management in South Africa, and aligns with much of the international research base, the strong emphasis that emerges on school-community relations offers important insights for school management development.
