Sources and definitions
Test results are from California’s state tests (CAASPP), spring 2026: the share of students tested in the level’s grades who scored Proficient or Advanced, per subject. California’s figure is our combination of the state’s published rows for the same grades. A ✓ marks a figure ahead of the others by more than twice the margin of error (on chronic absence, ahead means lower). Chronic absence and suspensions are the California Department of Education’s 2025–26 counts; “chronically absent” means a student missed 10% or more of school days. The absence and suspension references are the average California school we score at these schools’ level, each school counted once. The state growth measure is points above or below what the state expected from these students’ earlier scores, for grades 4–8, from the state’s spring 2025 release. Students per teacher is from the federal school directory, 2024–25, which also lists enrollment: Granada Hills Charter 5,927; Valley Academy of Arts and Sciences 757. Teacher experience is the California Department of Education’s staffing file for the school year shown (teachers only). A charter’s authorizer is from CDE’s charter term file and its term end from CDE’s Charter School Database.
