The document discusses how distributing leadership roles throughout a school organization can foster teacher leadership. It provides an example of how Edison Schools restructured their traditional top-down leadership model by implementing leadership teams, academy directors, lead teachers, and senior teachers to give more teachers leadership responsibilities. This distributed structure allowed for inclusive decision-making, collaborative teams, and internal professional development opportunities. The results were improved student achievement and the school becoming popular with a waiting list. The conclusion is that organizational structures facilitating teacher leadership can change the nature and scope of teacher leadership while also fostering school success.
