Brookside Elementary: The score is strong. The trajectory is stronger.
Brookside pairs 78% proficiency with gains that hold up when the school's returning cohort is tracked two years apart — the rare school that posts both.
Brookside Elementary scores 75 of 100 on SchoolScope's Scope Score — the 97th percentile of 5,721 California elementary schools (CDE CAASPP 2025).

Most rating sites would stop at “78% proficient” and call it done. Brookside deserves a closer read. It sits at the 97th percentile of 5,721 California elementary schools — but the ranking is the least interesting thing on this page.
The headline number: +10.9pp separates this year's grade 3 from its grade 5. The state average rises 4.6pp over the same span. Following the school's returning cohort from 2023 G3 → 2025 G5 points the same way.

ELA · CAASPP 2024–25Different students, same year — each bar is one grade's proficiency mix.
The honest read: the share exceeding rises 15.4pp across grades; the floor rises 10.4pp. 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.
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 94th percentile of California elementary schools, the state's around the 94th 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 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 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 Brookside Elementary in Oak Park, 75.3% of white students met or exceeded the ELA standard in 2025, compared to 76.2% district-wide and 61.8% statewide. Brookside Elementary trails its district average for white students by 0.9 percentage points in ELA. Other subgroups: White students (78.5% Math proficient); Asian students (89.7% ELA proficient). Data source: California Department of Education, CAASPP 2024-25. 194 students tested.
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.
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.
— 5 more groups are 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.

Where the path goes

The road from this school ends at Oak Park High, which sent 69 graduates to UC campuses last fall and teaches 23 AP subjects. Those numbers describe past cohorts — a child starting here today would reach Oak Park High around 2035, and 10 years is a long time for a school to hold still, and by the state's 2023 count 91% of Oak Park High's graduates enrolled in college somewhere, UC or not.

On the state's science test (CAST), 69% met or exceeded the standard — science is tested in grades 5 and 8 and once in high school, and it never enters the Scope Score.

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.
