This report describes a cohort of secondary school students, from grades 7 through 12, who were enrolled in District of Columbia Public Schools in October 1993, but who did not return by the official membership count of the following school year. This group included dropouts, transfers, court-ordered withdrawals, deaths, and serious illnesses. The dropout statistics are presented by racial/ethnic category, gender, age, and grade. Both dropout and migration statistics are presented by school, school level, school cluster, and city ward. Comparison statistics are presented for the present school year, 1993-94, and the 2 preceding years. For the past 3 years, the annual dropout rate has shown a steady trend, reflecting the relative consistency and reliability of the dropout accounting system. The total number of dropouts in the District's public schools for school year 1993-94 was 2,441, which represents 8.23% of the students at the secondary level. The out-migration rate, which reflects out-of-city transfers, was 2.99%. While the overall dropout rate declined somewhat from that of the previous year, the out-migration rate increased slightly. Ten appendixes contain a glossary and list of definitions, information on 2-year trends, recent dropout rates, a projection for the next 4 years, rates for other urban areas, and lists of the city's public schools by students, cluster, and ward. (Contains 23 tables, 8 figures, and 4 references.) (SLD)
