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 “22% proficient” and call it done. Arthur Hapgood deserves a closer read. Three in four of its students qualify for free or reduced lunch (California: 64%) — and reading the numbers without that context misreads the school.
The headline number: +13.1pp 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.

Arthur Hapgood Elementary scores 32 of 100 on SchoolScope's Scope Score — the 39th percentile of 5,721 California elementary schools (CDE CAASPP 2025).
This school hasn't fully recovered from the pandemic: 22% meet the standard today, versus 32% in 2019 — a gap worth asking about on a visit.

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 its two subjects part company here. It puts this school around the 13th percentile of California elementary schools in reading and the 43rd in math; ours, which blends the subjects, lands around the 93rd. 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 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.
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 Arthur Hapgood Elementary in Lompoc, 21.3% of low-income students met or exceeded the ELA standard in 2025, compared to 25.1% district-wide and 38.2% statewide. Arthur Hapgood Elementary trails its district average for low-income students by 3.8 percentage points in ELA. Other subgroups: Low-Income students (17.2% Math proficient); Hispanic students (22.7% ELA proficient). The largest proficiency gap is 20.7 percentage points for disabilities students. Data source: California Department of Education, CAASPP 2024-25. 317 students tested.
Low-income students here trail the state average for their group by 17 points in ELA — worth asking how the school is closing that gap.
6 of 14 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 14.6pp from grade 3 to grade 5 at this school. District average: +3.5pp.
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.

TK/K students miss school at roughly one and a half times the rate of Grades 4–6 students (35.7% vs 21.9%). Chronic absence here concentrates in the earliest grades — worth asking how the school works with new families on attendance.
24.1% of students miss a month or more of school, versus 17.9% statewide. High absence often tracks community stress — worth asking about on a tour.
What sits behind the school experience?

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.
$899 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.
District-level, from the district's own SACS general-ledger filing — school-by-school breakdowns aren't published by the state.

At 768 students, this school is well above the typical California elementary school (≈480).
Transitional kindergarten is offered here — confirmed by actual Census Day enrollment, not just the listed grade span.
On the state's science test (CAST), 22% 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.

Arthur Hapgood still trails on raw proficiency — and it's climbing faster than most schools anywhere near it — and that holds when you follow the school's own returning cohort across grades.
Subject proficiency describes tested students, while graduation describes a graduating cohort. These figures are not successive stages followed by the same students.

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.
