Summary:
ZIP code 94403 has six elementary schools in the San Mateo-Foster City district: five serve kindergarten through grade 5, while Bayside Academy serves kindergarten through grade 8. In 2025–2026, the six schools’ average proficiency was about 50% in ELA, 50% in math and 47% in science, but those averages hide exceptionally wide differences: College Park Elementary outscored Laurel Elementary by 67 percentage points in ELA, 65 in math and 46 in science—the clearest overall finding for families comparing schools in this ZIP code.
College Park led the group in all-grade ELA and math, with 82% and 83% proficient; it also led the K–5 schools in ELA and math in grades 3, 4 and 5. George Hall Elementary was another strong performer and led science at 70%, compared with 68% at College Park. At the other end, Laurel had the lowest all-grade results: 16% in ELA, 18% in math and 23% in science, and its grade 3–5 ELA and math results were below state figures throughout. Bayside’s all-grade ELA and math were above state averages, but its grades 3–5 results were below state figures in both subjects; its grades 6–8 results were above them.
From 2024–2025 to 2025–2026, the group’s average science proficiency rose 7 points, while ELA rose about 1 point and math changed by less than 1 point. Individual results varied: science increased 23 points at George Hall and 24 at Beresford Elementary, but fell 10 at College Park. SchoolDigger’s statewide percentile ranks also show contrasting paths: College Park moved from 96 to 97, while Laurel dropped from 18 to 8. For context, 2024–2025 free/reduced lunch eligible shares ranged from 14% at College Park to 77% at Laurel; these are observations, not explanations for results. Student-teacher ratios ranged from 18.3 at Meadow Heights to 23.9 at College Park. Bayside’s wider grade span means its all-grade figures are not directly equivalent to those of the K–5 schools.
