"Great Teachers and Great Leaders" (GTGL) is one of six research summaries issued by the U.S. Department of Education in support of its Blueprint for Reform. This review examines the presentation of research about improving teacher and administrator quality in GTGL. The review concludes that there are serious flaws in the research summary. The report, however, lacks sufficient analytic depth, does not present its evidence in a logical manner, makes sweeping claims, and draws conclusions based on weak data.
