In the wake of concern about the diversity of cadets/midshipmen selected by the service academies, Congress requested that the Secretary of Defense conduct a comprehensive assessment of the recruiting efforts, admissions policies, graduation rates, and career success rates of entrants and graduates at the United States Military Academy (USMA), the United States Air Force Academy (USAFA), and the United States Naval Academy (USNA). RAND was asked to provide assistance in responding to the congressional mandate by summarizing trends in accession and various outcomes of interest for the entry cohorts as a whole and for subgroups of interest. This monograph documents RAND's analysis of the data provided by the military services pursuant to the congressional mandate. The academies provide tuition-free, four-year undergraduate education and prepare entrants to be officers of the U.S. military services. Graduates are commissioned as officers for a minimum of five years. Each of the service academies admits between 1,100 and 1,350 entrants each year, and this has remained consistent over time and across the three academies. Each chapter includes footnotes. Appended are: (1) Continuation Rates of Graduates Who Completed Their ISO, 1993-2003 Graduating Classes; and (2) Active-Duty Service Obligations. (Contains 58 figures and 16 tables.)
