In this article, we report results of a survey of 1,397 teachers in 26 primary and 17 secondary schools in England as part of the Learning How to Learn project. We consider how school self-evaluation can be understood within an organisational learning frame. Factor analysis of teachers' responses helped us identify 4 dimensions of organisational learning approaches to school leadership and management. Comparisons were made between teachers' perceptions of school leadership and management practices and the values they placed on those practices. We discuss the usefulness of analysing values-practice gaps for furthering understanding of organisational learning approaches to school leadership and management. Analysis of gaps between teachers' values and practices reveals significant inconsistencies between perceptions of current practices and values across a broad spectrum of school leadership and management practices. Perceptions of practice were significantly behind the values that teachers place on each of the 4 dimensions of practice. (Contains 11 tables, 1 figure and 1 note.)
