Anticipating and Incorporating Stakeholder Feedback when Developing Value-Added Models

Abstract

State and local education agencies across the United States are increasingly adopting rigorous teacher evaluation systems. Most systems formally incorporate teacher performance as measured by student test-score growth, sometimes by state mandate. An important consideration that will influence the long-term persistence and efficacy of these systems is stakeholder buy-in, including buy-in from teachers. In this study we document common questions from teachers about value-added measures and provide research-based responses to these questions. The questions come from teachers in Baltimore City Public Schools, who are evaluated using a combined measure of which value-added is one component. We focus on teacher questions about value-added because value-added generates the most concern from teachers. We also connect teacher concerns about value-added to other components of the evaluation system, such as classroom observations, although at present these other components have not garnered as much attention from teachers.
