This study updates and adds to data presented in a March 1986 study on the dropout problem in Boston (Massachusetts) Public Schools. The current study has the following four major parts: (1) updates to student loss data for the entire 1985-86 school year; (2) demographic studies of dropouts for that period: analyses by gender, race, grade, district, and school; (3) updates to the cohort analyses for the 1985 graduating class; and (4) new cohort analyses done separately by race for the four graduating cohort years 1982 through 1985. A brief discussion of the implications for future research concludes the study. Among the study's tentative conclusions are the following: (1) there are many different subgroups among those who drop out; (2) more informative dropout categories must be developed; (3) a study is needed comparing students who have dropped out with those who have not; and (4) cohort and annual rate studies should be done annually.
