This edited volume examines innovative ways of preparing, supervising, and evaluating principals and explores factors that promote effective leadership practices. Chapter authors consider how principals’ leadership practices affect teachers’ instruction, satisfaction, commitment, retention, and effectiveness, and present evidence that principals can influence key student outcomes as well. Covering topics such as school leaders’ use of time, their efforts to reduce implicit bias, how leadership practices are associated with teachers’ workplace attitudes, leadership and student achievement, and how school leaders can best be supported under new federal legislation, this volume is a “must read” for educational leadership and policy faculty, school and district administrators, and researchers committed to promoting effective principal leadership.
