Each year describes that year’s tested students. Changes between years do not follow the same children over time. Cohort-growth evidence, when available, is labeled separately below.
Achievement-level percentages are not percentiles. “Developing” here is a test achievement level, separate from the SchoolScope performance band with the same name.
Most rating sites would stop at “11% proficient” and call it done. Columbia deserves a closer read. Two-thirds of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.
Test scores are one lens, and at this school they're a rough one right now. The sections below show the fuller picture — including the parts that are working.

Columbia Middle scores 16 of 100 on SchoolScope's Scope Score — the 5th percentile of 2,177 California middle schools (CDE CAASPP 2025).
Proficiency here is back to its pre-pandemic level — 11% meet the standard, about where the school stood in 2019.

Context — never part of the Scope Score
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 here the two measures disagree. Ours puts this school around the 70th percentile of California middle schools; the state's puts it around the 29th in reading and math together — a harder read than ours. We are not going to pretend one of those is the answer. Neither measure sees an individual child's classroom, and a disagreement this size is worth asking the principal about directly.
— 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.
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.
Who shares in the school’s results?
At Columbia Middle in Adelanto, 16.4% of low-income students met or exceeded the ELA standard in 2025, compared to 22.8% district-wide and 38.2% statewide. Columbia Middle trails its district average for low-income students by 6.4 percentage points in ELA. Other subgroups: Low-Income students (5.3% Math proficient); Hispanic students (19.7% ELA proficient). The largest proficiency gap is 15.4 percentage points for disabilities students. Data source: California Department of Education, CAASPP 2024-25. 550 students tested.
Low-income students here trail the state average for their group by 22 points in ELA — worth asking how the school is closing that gap.
5 of 17 student groups here are too small to report — a privacy protection, not a gap.
Results compare different grade groups in the same year, relative to the lowest tested grade. They do not track the same children over time. Groups with fewer than 10 tested students per grade are not shown.
Low-income student ELA proficiency rises by 17.4pp from grade 6 to grade 8 at this school. District average: +5.6pp.
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.
— 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.
What is it like to be a student here?
Student–teacher ratio is a schoolwide staffing measure, not an average class size.

Pay is set by the district, not the school.
55.0% of students miss a month or more of school, versus 18.1% statewide. High absence often tracks community stress — worth asking about on a tour.

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. 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.
