⭐ High Ceiling — Ask what happens for a kid who shows up behind — a high ceiling for the top can sit right next to thin support at the bottom, and the score alone won't show you which.
Most rating sites would stop at “79% proficient” and call it done. Mabel Mattos deserves a closer read. It sits at the 95th percentile of 5,744 California elementary schools — but the ranking is the least interesting thing on this page.
The headline number: 41.7% of English learners met the ELA standard — versus 10.4% statewide.

The story this school is actually telling
The school, grade by grade
ELA · CAASPP 2024–25Different students, same year — each bar is one grade's proficiency mix.
The honest read: the share exceeding rises 12.0pp across grades; the floor rises 10.5pp. The state average rises 4.5pp over the same span. Kids here gain ground the longer they stay — the pattern you want to see. A school visit and conversation with teachers will tell you more than this number.
The 6 things our score weighs
Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.
- Ask whether extra support — tutoring, counseling, small groups — reaches kids across income lines, not just the students already ahead.
- Ask whether the tour can step into a working classroom — watch how the teacher handles a student who's stuck.
- Ask to tour while school's in session, and notice how hallways and transitions feel — culture shows up between classes, not just in them.
- Ask how the school communicates with families when a child starts to struggle.
- Ask what a typical day looks like for a new student in the first few weeks.

What gets spent here
These measure different things: this figure is spending attributed to this campus, while district-wide figures also include central administration, districtwide programs, and the state's pension contributions made on the district's behalf — costs that never get assigned to a single school. The district number runs higher at nearly every school, not just this one.
The district's current expense of education per student, from CDE's annual SACS filing — the freshest district spending figure the state publishes.
District-level, from the district's own SACS general-ledger filing — school-by-school breakdowns aren't published by the state.
