The school principal's leadership role in the operation of the reading resource teacher program is discussed in terms of (1) his conception of the total school reading program, (2) his perception of and relationship to the reading resource teacher, (3) his efforts to secure faculty support for both the overall reading program and the reading resource teacher program, and (4) his administrative responsibilities in support of the program. The school principal has the critical role in the planning, implementation, and operation of the reading resource teacher program at the building level. He is the link between the teachers and the administrators of the school system, so he must understand, direct, and support any program that is to succeed in his building. Some of his administrative responsibilities that are directly related to the reading resource teacher program include budgetary, staff, and liaison considerations. References are included. (Author/NH)
