Principals and teachers work together to foster school improvement in areas ranging from targeted, short-cycle focus areas to long-term strategic planning. The principal should seek to understand, and involve multiple perspectives in this work and protect teachers’ time through scheduling, minimizing interruptions, and providing coverage to maximize their involvement and leadership in this work. Principals play an important role in empowering a shared leadership approach to school improvement. My ASCD book Insights into Action emphasizes the importance of innovation and improvement through the lens of school leadership.
