Vice-principals' role and their relationship with principals are of paramount importance in shaping the effectiveness of school management, particularly after the implementation of school-based management (SBM) worldwide. This paper reports primarily on prior studies on the vice-principalship and suggests a framework to help explain the different working relationships between principals and vice-principals. The framework is a matrix based on three dimensions, namely status, roles and management tasks. The framework was then examined through an illustrative case study. What emerged was that the framework provides a powerful means to explain the different combinations of relationship between principals and vice-principals. (Contains 4 tables and 2 figures.)
