Ways in which roles are being redefined as school systems move toward organizational structures based on shared decision making are described in this paper. Specifically, teachers need training to function as effective decision makers and principals must learn to be instructional facilitators. Principals acting as facilitators must possess skills in conflict resolution, communication, and group processes. The superintendent, as a facilitator of organizational change, has ultimate responsibility for coordination, implementing, and sustaining shared decision making. The board of education must support systemwide collaboration, develop guidelines, and exercise authority as a policymaker. A conclusion is that the implementation of shared decision making must encompass the entire organizational structure of a school district. (LMI)
