This document presents the executive summary of a research project undertaken to provide a national overview of the dimensions of the dropout problem, focusing specifically on gender differences; and to identify strategies that are being used to address the dropout problem, assess effectiveness of these strategies, and suggest ways that these strategies could be implemented elsewhere. It describes a research review and site visits to nine dropout programs. Findings are reported in two sections. The first section examines data on dropouts and presents major findings about differences in the dropout problem between males and females in the areas of the magnitude of the dropout problem, characteristics of school dropouts and returners, reasons students drop out of school, and consequences of dropping out of school. Findings related to promising education strategies are presented in the second section. General observations are discussed and guidelines are recommended for program designers to use in structuring dropout prevention efforts, including: (1) direct dropout prevention efforts at younger students who are potential dropouts; (2) establish linkages between different levels of schooling to facilitate student transition; (3) keep dropout prevention programs small in size; (4) focus programs initially on basic skills; (5) provide students with concerned adults; (6) provide students with regular feedback about progress; and (7) link job training to long-term employment. Recommendations for federal policy are made. (NB)
