Goal 2 isn’t shown because it tracks other measures.

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.
