Pantera Elementary: High scores, healthy climate, strong attendance. We looked for a catch — we didn't find one.
Pantera posts 52.6% exceeding the standard — versus 21.4% statewide — with climate numbers better than most. That doesn't make it perfect. It makes it worth a visit to find what numbers can't measure.
Pantera Elementary scores 75 of 100 on SchoolScope's Scope Score — the 97th percentile of 5,721 California elementary schools (CDE CAASPP 2025).
Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →
High Ceiling — Ask what happens for a kid who shows up behind — a high ceiling for the top can sit right next to thin support at the bottom, and the score alone won't show you which.
Most rating sites would stop at “77% proficient” and call it done. Pantera deserves a closer read. Two in five of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.
Pantera's low-income kids hit 78.5% 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.

Where its students land
The school, grade by grade
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 2.1pp across grades; the floor rises 11.2pp. The state average rises 4.6pp 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.
Pantera's most underrated number
78.5% 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
returning cohort
Percent exceeded, ELA only. SchoolScope's scored growth measure uses a different metric — mean scale-score change across ELA and Math; California's own matched-student model is below.
California's own answer to the same question
California runs its own growth model, following individual children in grades 4 through 8 rather than comparing school-wide averages the way we do. The two measures land in the same neighbourhood here — ours puts this school around the 84th percentile of California elementary schools, the state's around the 95th in reading and math together. Two different methods agreeing is the most you can ask of one year of test data.
— pts vs expected is scale-score points above or below what California's model predicted for these same children from their own prior-year scores. It is not a percentage and not a percent of anything. A typical California elementary school lands at +2 in reading, and the middle half of them fall between −5 and +9 — the spread is wide, so read the rank, not the sign. CDE blends two consecutive years into each published figure, so adjacent years share input data and no year-over-year trend can honestly be drawn from them. It covers grades 4-8 only, and it is not part of the Scope Score — we assessed it and left it out: it tracks school demographics roughly three times as strongly as our own growth measure does, and one published year is not enough to test how stable it is.
Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.
- Ask what changes between grade 3 and grade 5 here, and who teaches the older kids.
- 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.
How every group of students does here
At Pantera Elementary in Diamond Bar, 78.5% of low-income students met or exceeded the ELA standard in 2025, compared to 34.6% district-wide and 38.2% statewide. Pantera Elementary outperforms its district average for low-income students by 43.9 percentage points in ELA. Other subgroups: Low-Income students (64.0% Math proficient); Asian students (86.4% ELA proficient). The largest proficiency gap is 12.7 percentage points for hispanic students. Data source: California Department of Education, CAASPP 2024-25. 135 students tested.
7 of 13 student groups here are too small to report — a privacy protection, not a gap.
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.
Low-income student ELA proficiency rises by 9.5pp from grade 3 to grade 5 at this school. District average: +3.9pp.
California follows these children individually and predicts each one's score from their own prior year. Each row is read against the same group at a typical California elementary school — not against zero, and not against this school's all-students figure, because the state's expectation already differs by group.
— 1 more group is reported here with between 11 and 29 students. We hold those back on purpose: at that size the figure swings about 17 points on its own, and a quarter of such groups land past the state's top or bottom cut point by chance alone. They are listed with their student counts in the data appendix. — A group not listed at all had fewer than 11 students with a growth score, so California published nothing for it here. That is a privacy protection, not a judgment about those students. — Context only. None of this enters the Scope Score.

The road from this school ends at Diamond Ranch High, which sent 30 graduates to UC campuses last fall and teaches 21 AP subjects. Those numbers describe past cohorts — a child starting here today would reach Diamond Ranch High around 2035, and 10 years is a long time for a school to hold still, and by the state's 2023 count 80% of Diamond Ranch 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.
$531 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.

Whole scale-score points above or below what CDE's model predicted for these same children from their own prior-year scores — not a percentage, not a percentile. Statewide a typical school lands near +1 with a spread of about 13 points either side, so read a figure against its group's own typical value, not against zero. Muted rows have fewer than 30 students with a growth score — published by CDE, held back from the narrative sections above because at that size the figure swings about 17 points on its own. “Not categorised” is CDE assigning no band — English Only, Recently Reclassified, and English Learners Only receive a value and no band, for every school in the state. It is not a missing number. Most figures blend two consecutive years, so adjacent published years share input data and no trend line can honestly be drawn across them. A group absent from this table had fewer than 11 students with a growth score and was never published. Grades 4-8 only. None of this enters the Scope Score — it is more strongly correlated with school demographics than our own growth measure, and one published year is not enough to test its reliability.
