This document summarizes research on transformational school leadership. It begins by discussing the roots of transformational leadership theory in the work of James McGregor Burns and Bernard Bass. It then reviews evidence that transformational leadership has positive effects on teachers and school organizations, including teacher commitment, satisfaction, classroom practices, and school culture. The document outlines a school-specific model of transformational leadership with four dimensions: setting directions, developing people, redesigning the organization, and managing instruction. It provides details on the leadership practices within each dimension, such as building a shared vision, fostering group goals, and developing capacity in teachers.
