This study follows a cohort of first-time 9th graders in San Bernardino City Unified School District from 2001/01 to 2005/06 and documents their dropout, reenrollment, and graduation rates. For the one-third of dropouts who reenrolled in the district over that period, it reports course credit accrual and graduation outcomes as well as students' reasons for dropping out and the challenges districts face with their reenrollment. By focusing on reenrollees, this study contributes to shaping policy that addresses the broader dropout challenge. Appended are methodology, tables with details on census characteristics, and interview protocols. (Contains 1 box, 8 figures, 10 tables, and 14 notes.)
