Recent research has shown that, to exercise more effective leadership, principals need to match their behaviors with the appropriate needs and concerns of teachers. Concepts and tools from work done by the Research on Concerns-Based Adoption Project at the Austin campus of the University of Texas were employed to provide principals in the Palm Beach County (Florida) Schools with the understanding and skills that the role of instructional leadership demands. This paper first describes the concepts and tools derived from field-based research and selected for principals' use in enhancing leadership; it then describes the leadership program of inservice education for administrators, reports the techniques and strategies employed in developing principals' skills in utilizing the new concepts and tools, and provides a brief discussion of the implications of developing leadership skills.
