An Action Framework for PLC at Work Leaders

By focusing on what students learn rather than what they are taught, schools can redefine their mission and begin the transition to a professional learning community. After interviewing and observing principals, administrators, and teachers, the authors identify seven leadership practices that effective PLC leaders share, along with the techniques that have led them to sustainable success.
