Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
🚀 Growth Engine — Ask how the school tracks each kid's growth year to year, and what happens when a kid stalls instead of gaining.
Most rating sites would stop at “63% proficient” and call it done. Isleton deserves a closer read. The school sits in Isleton, where three in four students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Isleton's low-income kids hit 57.3% 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
Climbed from the 71st to the 93rd percentile since 2019 — past roughly 1200 elementary schools.

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 17.4pp across grades; the floor rises 4.4pp. 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.
Isleton's most underrated number
57.3% 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.

Change in proficiency from the lowest tested grade — which groups gain ground the longer they stay. Groups with fewer than 10 tested students per grade are not shown.

Showing up, and staying in class
TK/K students miss school at roughly twice the rate of Grades 4–6 students (22.2% vs 12.2%). Chronic absence here concentrates in the earliest grades — worth asking how the school works with new families on attendance.

The road from this school ends at Rio Vista High, which teaches 8 AP subjects. That number describes past cohorts — a child starting here today would reach Rio Vista High around 2035, and 10 years is a long time for a school to hold still, and by the state's 2023 count 57% of Rio Vista High's graduates enrolled in college somewhere, UC or not.
The people teaching here
Pay is set by the district, not the school.
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.
$1,525 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.
