This paper derives from a National College of School Leadership sponsored study conducted within schools in three English local authorities exploring what distributed leadership looked like in practice and how it was seen by headteachers and teachers in the 11 participating schools. On the basis of questionnaires, shadowing and workshops with representatives from the schools, six models of distribution were derived. In the final stages of the project these were tested with teachers and headteachers and further refined and published by the National College as a professional development activity. These six models from "formal" to "cultural" distribution may, it is argued, be seen as a developmental sequence, adapted to the context and stage of development of a school.
