If educators’ realities are filtered through the belief that they can do very little to influence student achievement, then it is likely these beliefs will manifest in their practice. The solution? Collective efficacy (CE)—the belief that, through collective actions, educators can influence student outcomes and increase achievement. Educators with high efficacy show greater effort and persistence, willingness to try new teaching approaches, and attend more closely to struggling students’ needs. This book presents practical strategies and tools for increasing student achievement by sharing: •Rationale and sources for establishing CE; •Conditions and leadership practices for CE to flourish; •Professional learning structures/protocols.
