Summary
Kimball is a K–6 elementary school in National City, serving 322 students in a community where nearby schools serve between 361 and 1,095 students. Its clearest academic strength is English language arts (ELA), while science is its biggest concern: in 2025–2026, 38% of students were proficient in ELA, 25% in math, and 19% in science, with science trailing the state by 17 percentage points.
Compared with the National Elementary district, Kimball was 3 points higher in ELA, but 3 points lower in math and 8 points lower in science. Among nine nearby schools with results that year, Kimball ranked third in ELA, fourth in math, and fourth in science. Its ELA result was 6 points above the nearby-school average; math was essentially even with the average, and science was 4 points below it. Compared with the state, Kimball was behind in all three subjects: by 11 points in ELA, 13 in math, and 17 in science. These results make literacy the clearest relative bright spot, with science the largest shortfall.
Scores have changed unevenly: from 2022–2023 to 2025–2026, ELA rose 3 points and science rose 7, while math was essentially flat and its gap behind the state widened by 3 points. Chronic absenteeism improved from 50% in 2021–2022 to 20% in 2025–2026—4 points below the district, but 2 above the state. SchoolDigger ranks Kimball at the 32nd percentile statewide, with 2 stars, down from the 42nd percentile in 2023–2024; its 2024–2025 student–teacher ratio was 24.7, the second-highest among nearby schools reporting a ratio. Its free/reduced lunch eligible rate was 82% in 2024–2025. SchoolDigger’s English Language Learner Students ranking fell from the 66th percentile in 2022–2023 to the 47th in 2023–2024, while Male Students ranked at the 18th percentile in 2025–2026, below the school’s overall 32nd percentile. These group rankings reflect relative standing and do not explain why it changed; comparisons also warrant care because Kimball is small and nearby schools serve different grade spans.
