Rather than following developers who tout the benefits of standardizing testing or opponents who focus on what they see as failure, independent scholar Phelps explains the its social and political implications and practical uses. He explains to non-specialists how and why such tests developed as ways to measure both aptitude and achievement, and how those applications soon diverged. He explains the early effects of testing in education, in which the results were largely ignored, and how educators began to refine and use high-stakes tests in public and higher education for a variety of purposes, including assessment of schools as much as students. He describes how developers create tests and work on quality assurance, and lists the potential risks (such as marginalization of certain groups) and benefits (such as correcting for upward grade drift) of standardized testing. Phelps's list of resources is particularly helpful. Annotation 2008 Book News, Inc., Portland, OR (booknews.com)
