Most rating sites would stop at “50% proficient” and call it done. Rio del Sol deserves a closer read. The school sits in Oxnard, where more than half of students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Rio del Sol's low-income kids hit 51.6% 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 seven-year arc
Has stayed near the 80th percentile since 2019.
This school hasn't fully recovered from the pandemic: 50% meet the standard today, versus 53% 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 rises 19.3pp across grades; the floor rises 31.0pp. 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.
Rio del Sol's most underrated number
51.6% of low-income students met the ELA standard — versus 38.2% for the same group statewide. That's the strongest kind of signal a school can post: it holds across income lines.
The 6 things our score weighs
Ask what changed — new curriculum, new principal, new program. Momentum has a cause, and a visit will find it.
- Ask how teachers track each child's growth over the year, not just where the class lands on test day.
- 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.

Showing up, and staying in class

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.
$845 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.
