This study concerns school dropouts in the Boston Public School system. It is divided into three sections which deal with: (1) a review of research studies on the causes of school dropout; (2) statistical analysis of the Boston situation by race and ethnic origin, gender, grade, and location; and (3) a review of prevention/intervention programs, such as social support programs, remedial education programs, alternative programs, and work study programs. A final section provides suggestions for additional readings. Reasons why students drop out were identified as follows: (1) poverty and lower socio-economic status; (2) school failure; (3) early pregnancy, lateness and truancy, delinquency, probation, and suspensions; and (4) alienation from school. The data is presented in the form of graphs and charts with analyses accompanying each exhibit. A bibliography is included. (CG)
