A systematic way to create collaborative school improvement is provided. The currently expanding role of administrators as staff developers is explored; 10 strategies are listed for the principal to use as a key player in staff development. Two specific organization development problem-solving strategies, Situation-Target-Plan (S-T-P) and Force Field Analysis (FFA), are explained, and an overview of "action research" principles is provided. On the basis of these three domains (staff development, organization development, and action research), an integrated model for collaborative school improvement is proposed. This model can be used to enhance staff development, create a collaborative environment for shared decision making, and provide an avenue for ongoing self-evaluation leading to school improvement. A brief account of a successful project using this model to increase student achievement is included. (Author/EMK)
