Figures from CDE’s state test, chronic absence and suspension files. Test figures cover every grade the district tests (California tests grades 3–8 and 11), so they differ from a profile’s rated grades. We combined the district’s schools ourselves, weighted by students and leaving out charter schools. Chronically absent means a student missed 10% or more of school days.
