Incentives, Selection, and Teacher Performance: Evidence From IMPACT

This research report, published by the Calder Center at American Institutes for Research, examines the effectiveness of IMPACT—the District of Columbia’s teacher evaluation and compensation system—which provides individually targeted and high-powered incentives linked to performance (measured by multiple scores). The report found that the program improved the effectiveness of the D.C. Public Schools’ teacher workforce, both through the exit of low-performing teachers and through the performance gains evident among those who remained.
