WWC Review of the Report "Incentives, Selection, and Teacher Performance: Evidence from IMPACT." What Works Clearinghouse Single Study Review
What Works Clearinghouse
The 2013 study, "Incentives, Selection, and Teacher Performance: Evidence from IMPACT" examined the effects of "IMPACT," a teacher evaluation system used in the District of Columbia Public Schools, on teacher retention and performance. "IMPACT" assigns each teacher a single performance score based on classroom observations, student achievement, core professionalism, and their contributions to the school. Based on these performance scores, teachers are assigned one of four ratings, Highly Effective, Effective, Minimally Effective, or Ineffective. The information needed to determine attrition and baseline equivalence was not provided in the study. Consequently, the What Works Clearinghouse (WWC) could not assess whether changes in teacher retention and performance were related to differences in the teacher characteristics at baseline. Therefore, the research described in this report does not meet WWC regression discontinuity design standards. A glossary of terms is also included.
