This report reviews the research literature from 1975-1983 on potential secondary school dropouts and strategies for effective dropout prevention programs. The information provided is intended to help communities in modifying and/or constructing treatment programs for potential dropouts. The report is divided into three sections. In the first section, Characteristics of Potential Dropouts, research from eleven sources is reviewed. A profile of a potential high school dropout is suggested, in which the dropout's characteristics are listed as poor academic and reading ability, a dislike of school, little participation in extracurricular activities, poorly educated parents, high grade retention, discipline problems, low socio-economic status, a broken home, poor self-concept, low aspirations, and high absenteeism. In the second section, Reasons for Dropping Out, literature from eight sources is reviewed and ten reasons for dropping out are suggested: lack of interest, academic failure, poor reading ability, discipline problems, poor student-teacher relationships, employment, marriage, pregnancy, dangerous school grounds, and high absenteeism. In the third section, Dropout Prevention Programs, programs from 15 sources are reviewed and categorized as alternative school programs, vocational education programs, school modification programs, or counseling programs. Intervention strategies are suggested, including individualized instruction, teaching basic academic skills and vocational education, improving teacher-student relationships, counseling, getting students involved in extracurricular activities, and helping students develop a positive attitude toward school. A chart and a list summarizing the preceding material is provided for each section. (NRB)
