In 1988, the United States Congress passed legislation that created the School Dropout Demonstration Assistance Program (SDDAP). The program provides funding for local educational agencies, community-based organizations, and educational partnerships to establish effective programs. This report, the second of two volumes, presents statistical data from a two-part evaluation to assess the effectiveness of dropout-prevention strategies used by the 89 projects that were awarded grants. Data were collected through annual surveys of all SDDAP projects and indepth studies of activities and achievements at 15 selected project sites. Data were collected at the 15 sites through site visits, student and teacher surveys, and document analysis. The report identified the organizational characteristics of effective dropout programs and the program strategies that were most effective in preventing students from dropping out of school and in encouraging dropouts to reenter school. Appendices contain data tables for elementary, middle, and high school projects, methodological notes, and copies of data-collection instruments used in the implementation study and the outcomes study. (Contains 46 tables). (LMI)
