"Teacher-Powered Practices: How teacher teams collaboratively lead and create student-centered schools" focuses on how innovative teachers are radically changing the ways schools are designed and run. The how here are the common practices, structures, and processes teacher-powered teams design and use daily. The guide identifies nine common practices used at teacher-powered schools, and includes examples written by teacher-powered leaders who describe what the practice looks like at their site. These nine practices are built on research, the work of our Teacher-Powered Ambassadors, interviews with educators, and site visits at more than 120 teacher-powered schools over the last decade. These practices are not final or static. They will continue to evolve as teams create new and innovative ways to lead their schools. The nine practices are as follows: (1) Keep Students at the Center of Decision-Making; (2) Meaningfully Involve Families and Communities; (3) Honor Student Voice and Choice; (4) Cultivate a Collaborative Culture; (5) Embrace Transparency in Decision-Making; (6) Create Shared Leadership Structures; (7) Reimagine and Rotate Leadership Positions; (8) Engage in Peer Observation; and (9) Take On a Learner Mindset.
