Improving the nation's public schools is one of the highest priorities of federal, state, and local government in America. Recent research has shown that the quality of the principal is, among school-based factors, second only to the quality of the teacher in contributing to what students learn in the classroom. New programs to develop school leaders who can exercise vigilance over instruction and support effective teaching practices are not likely to succeed, however, if they are inconsistent with other state and district policies affecting school leadership. This volume reviews efforts to create more-cohesive policies and initiatives to improve instructional leadership in schools; describes how states and districts have worked together to forge such policies and initiatives; and examines the hypothesis that cohesive systems improve school leadership. Such efforts appear to be a promising approach to developing school principals engaged in improving instruction.
