The best explanation of standardized testing is Daniel Koretz’s Measuring Up: What Educational Testing Really Tells Us.—Diane Ravitch, The New York Review of Books

Every parent who uses league tables as a basis for placing his or her child in a school, whether in the U.S. or anywhere else, should read this book.—Lee Harvey, The Times Higher Education Supplement

Test scores are objective, scientific, and easy to understand—so what’s the problem? It turns out that there are a lot of problems and that we would do well to try and understand them better. Daniel Koretz’s Measuring Up is an excellent place to start. The book is hard to classify. It is too sophisticated to be called a primer. There are no equations, so it can’t be a measurement book. (Also, it is entertaining to read.) It says good things about testing and test use and takes apart some arguments of testing opponents, so it can’t be an anti-testing book. But, it raises profound challenges to the interpretation of score trends on high-stakes tests, to the meaning of achievement trend and gap reports in terms of percent proficient, to the interpretation of crossnational achievement comparisons, and to popular assumptions about testing of students in special populations (including some assumptions written into law). So, it can’t be a protesting book, either… He does a great service by clarifying measurement principles in the context of widespread testing uses and misuses.—Edward Haertel, Science

Deconstructs the complexities of achievement testing for the educational layman.Education Week

Koretz has written the book on educational testing most educators and educational policy makers have been waiting for, even if they don’t know it. In a culture defined by whether one is attacking or defending the messenger, the author’s endeavor is to explain what educational testing does, and does not, reveal about how students and their schools are performing… For someone looking for a good lay explanation of essential topics such as score reliability and validity, measurement error, and the relationship between high-stakes testing and score inflation, this is the book. The style is eminently readable and the topics are profoundly important.—D. E. Tanner, Choice

This is the most easily understood presentation I know of the deceptively complex world of educational testing, and the most important current issues. It should be welcomed with relief by a very broad audience, much of which is ignored in most presentations on testing. I would love to see it used in courses for virtually all future administrators, policy makers, and teachers. Anyone directing testing programs in school districts and states will find this invaluable when they have to explain what they’re doing. This book is badly needed.—H. D. Hoover, Professor Emeritus, University of Iowa

Here we are, lost in Testland, bombarded by data about how well or poorly we or our kids have done on the latest exam. What do test results mean? Every expert has a different explanation. What to do? Read Daniel Koretz’s new book, as soon as possible. Never have I seen a clearer or more sensible exploration of our testing frenzy. I thought one chapter, ‘What Influences Test Scores, or How Not to Pick a School,’ was all by itself worth the price of the book. Read it and relax.—Jay Mathews, education reporter and columnist for the Washington Post

Jacket: Virtue Politics: Soulcraft and Statecraft in Renaissance Italy, by James Hankins, from Harvard University Press

Q&A with James Hankins, author of Virtue Politics: Soulcraft and Statecraft in Renaissance Italy

With Virtue Politics, James Hankins has delivered a bold, revisionist account of the political thought of the Italian Renaissance—from Petrarch to Machiavelli—that reveals the all-important role of character in shaping society, both in citizens and in their leaders. We spoke to him about the importance of virtue to leadership in Renaissance Italy—and its relevance to our own time.
