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 44.7/100 — 5.9 points above the state average, with 1 of 3 in the Strong band.
3 elementary schools span 15 points around an average of 44.7.
Discovery Bay Elementary (54/100) holds the Strong band — 36.8% of its students exceed the state standard, against a level average of 25.8%.
Only 3 campuses at this level — one school's year moves every number in this chapter.
The middle years
The middle schools average 26.9/100 — 11.7 points below the state average. Here is what that number does and doesn't say.
All 2 middle schools land within 4 points — the average is a fair summary here.
Excelsior Middle is the strongest option at 29/100 — 14.3% of its students exceed the state standard.
21.1% 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 Discovery Bay Elementary at 54/100 — confirm the exact boundary with the district before the house.
1 of the 5 ranked schools is a charter — enrollment paths that don't depend on your address. If your zoned school sits low in the appendix below, those lotteries and applications are the levers worth the paperwork.
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.

What this page can't see: whether a campus feels safe and glad at 8 a.m. If a path above looks workable, the next step is a visit.
