Investing in Development: Six High-Performing Schools Implement the Massachusetts Teacher Evaluation Policy.

We studied how six high-performing, high-poverty schools in one large Massachusetts city imple- mented the state’s new teacher evaluation policy. The sample includes traditional, turnaround, restart, and charter schools, each of which had received the state’s highest accountability rating. We sought to learn how these successful schools approached teacher evaluation, including classroom observations, feedback, and summative ratings. We interviewed 142 teachers and administrators and analyzed data using sensemaking theory, which considers how individuals’ knowledge and beliefs, the context in which they work, and the policy stimuli they encounter affect implementation. All schools prioritized the goal of developing their teachers over holding them accountable. The spill- over effects of additional policies affected how these schools approached implementation.
