Summary
Harrison Elementary is a K–8 school in Pomona, California, serving 328 students in Pomona Unified. In 2025–2026, 24% of students were proficient in English language arts (ELA), 13% in math and 8% in science, all below district and state results. The most important finding is that academic results are low across all three subjects, not just one.
Compared with nearby schools, Harrison was lowest in ELA and math, and second-lowest in science among the nine nearby schools with reported all-grade results. Those schools averaged 52% in ELA, 43% in math and 35% in science; Harrison was behind those averages by 28, 29 and 27 percentage points, respectively. Science was its largest gap against both the district and state: 8% proficient, versus 23% districtwide and 36% statewide. Math was comparatively closest to those benchmarks, at 13% versus 25% in the district and 38% statewide. Third grade stands out as a relative bright spot: ELA proficiency was 34%, above the district’s 31%, while third-grade math was 29%, close to the district’s 30%.
Scores have fluctuated, but the gap with the state has grown: from 2022–2023 to 2025–2026, Harrison’s ELA, math and science results fell by 2, 1 and 3 percentage points, while state results rose by 3, 4 and 6 points. Chronic absenteeism improved by 27 points, to 25% in 2025–2026, but remained above the state’s 18%. SchoolDigger ranked Harrison 5,329 of 5,804 statewide (8th percentile, 0 stars); its percentile ranking fell 15 points from 2021–2022. In 2024–2025, its student–teacher ratio was 18.7, lower than most nearby schools, and 93% of students were free/reduced lunch eligible. California is identified as a statewide free-meals state, so that eligibility figure does not indicate who pays for meals.
