Principal leadership has been identified as the key to successful implementation of inclusive education for students with disabilities. Prospective principals require knowledge, skills, and dispositions to equip them to work with key stakeholders to initiate and sustain inclusive practices within their schools. The purpose of this action research study was to (a) examine principals' perspectives on their preservice education needs to prepare them for a leadership role in an inclusive school; (b) to develop and implement an experimental graduate-level course in Educational Administration focusing on leadership in inclusive education; and (c) collect data on student and instructor experiences and perspectives throughout the course. This paper reports on the course development and implementation within two settings in subsequent semesters. Findings indicate agreement on the need for preservice education to prepare principals for leadership within inclusive schools and recommendations for course content and delivery are discussed.
