🌱 Building Momentum — This label means the data doesn't clearly sort the school one way or the other — ask what the school is proud of, and what it's working on.
Most rating sites would stop at “60% proficient” and call it done. Los Osos deserves a closer read. The school sits in Los Osos, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Los Osos's low-income kids hit 53.7% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.

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 slips 6.5pp. The state average falls 0.5pp over the same span. The school's 8th graders aren't posting a wider lead than its 6th graders. One question worth asking on a tour: are the strongest students being pushed, or coasting? A school visit and conversation with teachers will tell you more than this number.
Los Osos's most underrated number

The 6 things our score weighs
Ask the principal what changes between grade 6 and grade 8. Ask who teaches the older grades, and what the school does when a child starts falling behind.
- Ask how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
- Ask what changes between grade 6 and grade 8 here, and who teaches the older kids.
- 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.

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.
$1,162 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.
