📈 On the Rise — Ask how many years the improvement has held, not just the latest one — one strong cohort and a real turnaround can look identical in a single year of data.
Most rating sites would stop at “29% proficient” and call it done. George Lincoln Mosher deserves a closer read. The school sits in Stockton, where two-thirds of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

This school hasn't fully recovered from the pandemic: 29% meet the standard today, versus 44% in 2019 — a gap worth asking about on a visit.

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 holds steady across grades; the floor rises 26.6pp. The state average rises 4.5pp over the same span. 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 how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
- Ask what typically leads to a suspension, and what happens before it gets there.
- 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.
$472 per student arrives as federal Title funding — a measure of concentrated need, not school quality.
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.
