Research confirms that effective principals are the key to building a culture of great teaching and learning in schools. Every aspect of learning is influenced by the quality of the school’s leaders, from the strength of the teachers to the health of the school environment. School principals serve as both the managers of staff and the builders of school community. As states are pursuing various education reforms necessary to support the implementation of more rigorous standards that will more accurately measure students readiness for college or career training, governors and other state leaders have many opportunities to make policy decisions that will support principals so that they can improve the quality of teaching and learning in every school across a state.
