This data brief provides an enrollment snapshot of youth in the Continuation High Schools and district-operated Community Day Schools ("alternative schools") for youth over the age of 16 in the following Unified School Districts: (1) Long Beach; (2) Los Angeles; (3) Fresno; and (4) Oakland. Unless otherwise noted, these data are reported at the district level. The authors estimate that the sample of four districts represents approximately 20 percent of the alternative school population across the state.
