American educational policies over the last 40 years have represented an uninterrupted movement toward centralization. This article analyzes three terms that have become critical to the centralization of American education. More specifically, this article reviews the development, language, and source of the thematic terms and associated language of "achievement gap", "NCLB", and "school turnaround". The author contends that the level of each term's entrenchment in American education varies but that their impacts have all grown from a top-down initiative, and although the terms represent separate concepts, they have been linked in meaningful ways to drive centralization.
