This paper offers highlights from the final report of Stanford's School Leadership Study, which should be available in January 2007. It discusses various policy and resource factors that enhance or impede the implementation of exemplary programs that develop and support principals. Among the research questions that guided this study were a set that dealt with resources and supports for exemplary programs: (1) What state, district, and institutional policies foster the development of exemplary programs? How are they supported politically, organizationally, and financially?; (2) How do state and district financing policies shape the configuration of professional development programs available to support school leaders?; and (3) What does it cost to provide an exemplary professional development program? First, the authors discuss the landscape of state policies and state investments in leadership development. Second, they explore the costs of these programs and their revenue sources. Finally, they discuss implications for other organizations that wish to create or sustain development programs for principals. The authors hope that this exploration of resources and supports for exemplary programs will illuminate the creation and implementation of leadership development programs for organizations seeking to enhance their supports for school leaders.
