The Los Angeles Unified School District has funded several innovative prevention/recovery programs to determine indicators that will help local schools identify the potential early leaver. This annual study for the 1983-84 school year examines the number of students in grades 10 through 12 who left school without a diploma. Findings cover all regular senior high schools, opportunity schools, and magnet school programs. Comparison data provided are based on the following: (1) sex, (2) grade, (3) age, (4) ethnicity, and (5) reason for leaving. Significant facts include the following: (1) the 10,555 early leavers represent a slight increase from previous years; (2) more than 60 percent of leavers left during the second semester; (3) most early leavers are male; (4) continuation high schools had the largest percentage of leavers; (5) magnet schools had the fewest leavers of all non-special-education programs; (6) the percentage of early leavers (8.1 percent) was the highest since the district began its studies; (7) "whereabouts unknown" and "overage" represent over 60 percent of early leavers; and (8) the number of early leavers at grade 10 is higher than grades 11 and 12. It is recommended that the district should train teachers and counselors to identify potential early school leavers and provide them with counseling services. Early prevention programs to help students before the 10th grade, presention programs to help students before the 10th grade, and efforts to find students shortly after they leave school to encourage them back into an educational program are also suggested. Nine data tables are appended. (LHW)
