Loomis Basin Charter: High scores, real growth, strong attendance. We looked for a catch — we didn't find one.
Loomis Basin Charter posts 45.4% 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.
Loomis Basin Charter scores 66 of 100 on SchoolScope's Scope Score — the 91st 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 →
Strong All-Around — Ask about what we don't score — class size, electives, the feel of a classroom — strong numbers everywhere on paper don't mean every classroom feels the same.
Most rating sites would stop at “75% proficient” and call it done. Loomis Basin Charter deserves a closer read. It sits at the 91st percentile of 5,721 California elementary schools — but the ranking is the least interesting thing on this page.
The headline number: 45.4% of students scored in the top band on the state test. The California average is 21.4%.
As a charter, Loomis Basin Charter enrolls by application rather than address. That changes how you get in, but it doesn't change the score.

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 18.4pp across grades; the floor rises 11.4pp. 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 5 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 — and here the two measures disagree. Ours puts this school around the 72nd percentile of California elementary schools; the state's puts it around the 90th in reading and math together — a better 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 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 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 Loomis Basin Charter in Loomis, 80.8% of white students met or exceeded the ELA standard in 2025, compared to 71.2% district-wide and 61.8% statewide. Loomis Basin Charter outperforms its district average for white students by 9.6 percentage points in ELA. Other subgroups: White students (69.1% Math proficient). Data source: California Department of Education, CAASPP 2024-25. 234 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.
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.
— 3 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 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.
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.
