Each level is scored on its own scale — elementary, middle, and high are never ranked against each other.
The elementary years
The elementary schools average 24.6/100 — 14.3 points below the state average. Here is what that number does and doesn't say.
All 3 elementary schools land within 2 points — the average is a fair summary here.
Cucamonga Elementary is the strongest option at 26/100 — 5.7% of its students exceed the state standard.
22.4% of students are chronically absent (state: 17.9%) — chronic means missing 10% or more of the school year. Whatever the scores say, ask each school what it is doing about attendance.
The middle years
One middle school: Rancho Cucamonga Middle at 29/100 — the whole story at this level is one campus.
One dot, one school — there is no spread to read at this level.
Rancho Cucamonga Middle is the strongest option at 29/100 — 8.2% of its students exceed the state standard.
25.4% of students are chronically absent (state: 18.1%) — chronic means missing 10% or more of the school year. Whatever the scores say, ask each school what it is doing about attendance.
What it means for your family
Compare schools at your child’s level before deciding on an address. The strongest attendance-zone candidate is Cucamonga Elementary at 26/100 — confirm the exact boundary with the district before the house.
No charters or magnets among the ranked schools here, so the main lever is an intra-district transfer — California districts run them on their own windows and criteria. If your zoned school sits low in the appendix below, ask the district office for this year's dates.
A band is a position, not a prophecy — 1 campus here ranks as On the Rise, its returning cohorts gaining more than most schools statewide. Ask your school two questions: what happens for a kid who arrives behind, and what the classroom looks like for one who arrives ahead.
