🌱 Building Momentum — This label means the data doesn't clearly sort the school one way or the other — ask what the school is proud of, and what it's working on.
Most rating sites would stop at “41% proficient” and call it done. Waterloo deserves a closer read. The school sits in Stockton, where three in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
The seven-year arc
Climbed from the 28th to the 47th percentile since 2019 — past roughly 300 middle schools.
The pandemic drop is behind this school: 41% of students meet the standard today, above the 32% who did in 2019.

The story this school is actually telling
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 5.7pp across grades; the floor rises 3.1pp. The state average rises 0.1pp 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
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 — and its two subjects part company here. It puts this school around the 21st percentile of California middle schools in reading and the 68th in math; ours, which blends the subjects, lands around the 46th. A gap that size between math and reading in one building is worth asking about directly — one year of data can't tell you whether it is the teaching, the cohort, or noise.
— 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 middle school lands at −1 in reading, and the middle half of them fall between −8 and +6 — 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 how the school challenges kids who clear the standard early. The gap between meeting and exceeding is where pacing shows.
- 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 Waterloo Elementary in Stockton, 35.6% of low-income students met or exceeded the ELA standard in 2025, compared to 33.7% district-wide and 38.2% statewide.

Data source: California Department of Education, CAASPP 2024-25. 225 students tested.
7 of 15 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 16.6pp from grade 6 to grade 8 at this school. District average: +23.3pp.
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 middle school — not against zero, and not against this school's all-students figure, because the state's expectation already differs by group.
— 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 Linden High, which sent 9 graduates to UC campuses last fall and teaches 7 AP subjects. Those numbers describe past cohorts — a child starting here today would reach Linden High around 2031, and 6 years is a long time for a school to hold still, and by the state's 2023 count 76% of Linden High's graduates enrolled in college somewhere, UC or not.

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. “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. Long-Term English Learner counts cover grades 6-8 only (CDE), so that row is not comparable to the All Students row. 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.
