Measurement: Interdisciplinary Research and Perspectives 13, no.1: 1–25.1536-6367http://nrs.harvard.edu/urn-3:HUL.InstRepos:29397694Accountability has become a primary function of large-scale testing in the U.S. The pressure on educators to raise scores is vastly greater than it was several decades ago. Research has shown that high-stakes testing can generate behavioral responses that inflate scores, often severely. I argue that because of these responses, using tests for accountability necessitates major changes in the practices of educational measurement. The needed changes span the entire testing endeavor. This paper addresses implications for design, linking, and validation. It offers suggestions about possible new approaches and calls for research evaluating them.en-USJournal Article2016-11-1610.1080/15366367.2015.1000712
