Based on research from the Bill & Melinda Gates Foundation and the experiences of nearly 3,000 teachers across the United States, Vicki Phillips and Lynn Olson reveal multiple ways to identify effective teaching and provide teachers with actionable, reliable information they can trust to continuously improve their performance.

Teachers and administrators will learn how and why it's critical to (1) measure effective teaching, (2) ensure high-quality data, and (3) invest in improvement.

Armed with practical ideas for getting started at both the school and district levels, Phillips and Olson remind us that the best way to evaluate teaching performance is to use a balanced approach that includes multiple measures.
