Best Public Schools in Zip Code 94603

Zip code 94603 has eight schools: five elementary schools, one middle school, one high school, and one K–12 alternative school, together spanning kindergarten through grade 12. In 2025–2026, seven schools reported test results; their average proficiency was 15% in English language arts (ELA), 12% in math, and 8% in science, compared with California’s 49%, 38%, and 36%. The clearest area-wide finding is that every current-reporting school’s all-grades results were below the state average in all three subjects, with the largest average gap in ELA: 34 percentage points.

Madison Park Academy Elementary led the current-year group in ELA and math, at 20% and 19%, but still trailed the state by 29 and 20 points. Elmhurst United Middle led science at 14%, 22 points below the state. At the other end, Fred T. Korematsu Discovery Academy Elementary had the lowest ELA result, 5%, and a reported science result of 0%; those were 45 and 36 points below state results. Madison Park Academy 6–12 had the lowest math result, 7%, 32 points below the state. Brookfield Elementary was a notable exception to the general trend, placing second among elementary schools in current-year ELA and math.

Brookfield was also the only school whose results rose in all three subjects from 2024–2025 to 2025–2026: gains of 13 points in ELA, 8 in math, and 5 in science. Across the seven schools with results in both years, group averages edged down in ELA and fell about 1 point in math and science, while state results rose. SchoolDigger’s reported percentile for Brookfield rose from 1 to 6; Madison Park Academy Elementary fell from 14 to 7. As context, Brookfield’s directly certified for free meals share was 68% in 2024–2025; Lodestar: A Lighthouse Community Charter Public reported 97% free/reduced lunch eligible that year, a different measure. Lodestar’s 2024–2025 math result was 24%, the highest among all eight schools that year, but it has no 2025–2026 result; its K–12 span also differs from most schools. Comparisons reflect different grade spans, and Lodestar’s results are from an earlier year.
