Summary
College Park Elementary is a K–5 school with 431 students in San Mateo, serving families in the San Mateo-Foster City School District. Its clearest strength is consistently high achievement: in 2025–2026, it led its same-district K–5 peers in English language arts, math, and science, and ranked second among nearby K–5 schools in all three subjects, behind South Hillsborough.
College Park was strong against both local and statewide benchmarks: 82% of students were proficient in English language arts, 83% in math, and 68% in science, compared with statewide rates of 49%, 38%, and 36%, respectively. Its results were also above district rates of 53%, 50%, and 45%. Math showed the largest advantage over the state, while science was the relative soft spot: its lead over the average of seven nearby K–5 schools was 28 points, compared with 35 points in math and 36 in English language arts. Within the school, fourth-grade English language arts stood out at 90%, versus 71% in third grade.
Results remain high, but the trend deserves attention: science fell from 82% in 2022–2023 to 68% in 2025–2026, a 14-point decline; English language arts was down 4 points overall, while math was down 2. The school’s gaps over state results narrowed in all three subjects, most notably by 20 points in science. SchoolDigger ranked it 173rd of 5,804 California schools, at the 97th percentile with 5 stars. Chronic absenteeism was low at 4%, compared with 15% districtwide and 18% statewide. Its 23.9 student-teacher ratio in 2024–2025 was slightly above the nearby K–5 average of 22.4, and 14% of students were reported as free/reduced lunch eligible that year, below the nearby-peer average of 41%. SchoolDigger’s statewide effectiveness rankings were lower for Asian students, at the 72nd percentile, and multi-racial students, at the 74th percentile, than for the school overall; the multi-racial ranking fell from the 93rd percentile in 2023–2024.
