This article introduces a new approach for evaluating the quality of healthcare providers, including an integrated solution to several problems that limit the usefulness of available methods. Our approach combines information from all the quality indicators available for a provider (e.g., from...

This paper clarifies four areas of confusion about value-added methodology and its role in teacher evaluation: (1) use of value-added information; (2) consequences for teachers versus those for students of classifying and misclassifying teachers as effective or ineffective; (3) reliability of...
