This keynote talk addresses future trends in educational administration and reviews the ways in which attention to professional development for school administrators can help people to become better prepared for the challenges of today and tomorrow. Future trends include (1) a growing awareness of the importance of instructional leadership; (2) greater focus on the roots, rather than the symptoms, of behavioral disorders; (3) continuing concerns about financial support; (4) pressure to include more women and minorities in educational administration; and (5) participative school management. In the following discussion of professional development, the term "Planned Learning Experience" is first defined as any activity that provides a practicing administrator with knowledge or skills, or that changes attitudes, and is deliberately planned and presented as a learning event. The general range of learning experiences is described. Basic purposes and assumptions that have been the foundation of most current approaches to planned learning for school administrators are then discussed, along with evidence for the effectiveness of various models and approaches.
