75 is the typical California school. 100 is the best result in the state. How we score schools

Test results are from California’s state tests (CAASPP), spring 2026. Each figure is the share of students tested in the level’s grades who scored Proficient or Advanced, for one subject. California’s figure is our combination of the state’s published rows for the same grades.

“Clearly ahead” marks a figure that is 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 average school is the average California school we score at these schools’ level, with each school counted once.

The year-by-year chart shows each spring’s results for grade 11. Each year is a different group of students, so the chart does not show how the same students changed.

Students and students per teacher are from the federal school directory, 2024–25. Students from low-income families are students counted as eligible for free or reduced-price meals in the California Department of Education’s 2024–25 count.

Teacher experience is the California Department of Education’s staffing file for the school year shown (teachers only).
