Endorsements: At a time when private think-tanks seek to advance their ideological agendas through what is often shoddy research, this book is both a welcome corrective to and a reminder of the dangers of the mis-use of data in significant educational policy debates. - Michael W. Apple, University of Wisconsin, Madison Democracy thrives when a nation insures itself of a well-informed populace. The Think Tank Review Project helps our nation meet that goal by debunking bad social science, much of which emanates from the many highly partisan and well-funded think tanks that have developed over the last few decades. This book presents the best of the Project's reviews in a compelling indictment of think tank reports and their influence. - David Berliner, Arizona State University Education policy over the past thirty years has been powerfully influenced by well-funded and slickly produced research reports produced by advocacy think tanks. The quality of think tank reports and the value of the policies they support have been sharply debated. To help policymakers, the media, and the public assess these quality issues, the Think Tank Review Project provides expert third party reviews. The Project has, since 2006, published 59 reviews of reports from 26 different institutions. This book brings together 21 of those reviews, focusing on examining the arguments and evidence used by think tanks to promote reforms such as vouchers, charter schools and alternative routes to teacher certification. The reviews are written using clear, non-academic language, with each review illustrating how readers can approach, understand and critique policy studies and reports. The book will be of interest to practitioners, policymakers, researchers, and anyone concerned with the current debates about educational reform.
