Based on the belief that the popularity of accountability periodically waxes and wanes in education, this article outlines a bit of the history of the concept and defines and explains educational accountability. The author traces the roots of accountability back to the 1858 Newcastle report, the first comprehensive survey of English elementary education. He also finds a precursor in Frederick Taylor's efficiency movement in the early twentieth century. Several definitions and models of educational accountability are offered, all emphasizing the need for a plan of action, specific goals, and the evaluation of outcomes. A four-part process to use when developing an accountability program is briefly outlined and a short model for systems analysis is also presented. Accountability in the state of Texas is outlined (including, in the appendix, a list of the dimensions of accountability as set forth by the Texas Education Agency). Finally, the author advocates accountability as a cooperative endeavor among students, community, and the school. (Author/JM)
