How Credible is the Evidence, and Does It Matter? An Analysis of the Program Assessment Rating Tool

Abstract

This study empirically examines the quality of evidence that agencies provided to the Office of Management and Budget in assessments using the Program Assessment Rating Tool (PART), which was introduced in 2002 to strengthen the process for evaluating public program effectiveness and holding agencies accountable for results. The author finds some significant, positive associations between the quality of evidence and PART ratings, but no discernible consequences for program funding over time.
