Teacher supervision and evaluation practices can serve as powerful levers for improving teaching, but few school leaders know how to go about implementing practices that are fair and constructive. This book introduces a principles-based framework for supervising teachers and evaluating their performance for achieving optimal results. This approach does not make test results part of the teacher’s evaluation. Instead, it encourages teachers to focus on student learning and test results in ways that are candid, honest, and productive. This is an invaluable aid for principals, instructional leaders, and teacher coaches.
