School Culture,School Effectiveness and School Improvement

The relevance of the concept of culture to school effectiveness and school improvement is explored. Two typologies are developed. The first proposes four ‘ideal type’ school cultures, based on two underlying domains; the second, a more elaborate and dynamic model, proposes two ‘ideal type’ school cultures, based on five underlying structures. Each is discussed for its heuristic, conceptual, methodological and explanatory potential in research in the fields of school effectiveness and school improvement. In distinguishing collegial cultures from collaborative styles, the article advances recent writing on collaboration. From the theory hypotheses about the relationship between school culture and school effectiveness and improvement can be derived as well as techniques to test such hypotheses.
