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 49.1/100 — 10.3 points above the state average, with 3 of 5 in the Strong band.
5 elementary schools span 19 points around an average of 49.1.
Cullen Elementary (58/100) holds the Strong band — 33.2% of its students exceed the state standard, against a level average of 28.9%. 1 school here ranks as a Growth Engine — returning cohorts gaining more than most schools statewide.
What these numbers can't see: class sizes, arts, teacher turnover, how a hallway feels at 8 a.m. Strong scores are the start of the question, not the answer.
The middle years
Consistently strong: all 2 middle schools land within 8 points of each other, averaging 51.8/100 — 13.2 points above the state average.
All 2 middle schools land within 8 points — the average is a fair summary here.
Goddard Middle (56/100) holds the Strong band — 36.6% of its students exceed the state standard, against a level average of 29.4%.
Only 2 campuses at this level — one school's year moves every number in this chapter.
The high school years
One school defines the top: Glendora High sits 43 points clear of the field — the other 1 high schools are a different conversation.
43 points separate the strongest and weakest of these 2 high schools — the average hides more than it tells.
1 continuation/alternative school not plotted — it ranks within its own class, not on this statewide axis.
Glendora High (71/100) holds the Strong band — 31.1% of its students exceed the state standard, against a level average of 16.3%. 1 school classifies as Strong All-Around — no weak dimension we measure.
30.2% of students are chronically absent (state: 23.1%) — 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 Cullen Elementary at 58/100 — 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 — 3 campuses here rank as On the Rise (2) or Growth Engine (1), their 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.
