In Chapter 2 we explained how the ideas underpinning this approach to school improvement were developed through a pilot project. This led to the conception of the reflective action planning process as a model for teacherled school improvement. In this chapter, we set out the fundamental principles underpinning the model. We outline ways in which the school/ HEI partnership can be established, and suggest strategies for the setting up of a RAP (reflective action planning) group in a school. In Chapter 4 we will consider each element of the process in detail.
