Harry Dewey Fundamental Elementary serves 408 students in grades K–6 in Fair Oaks, within San Juan Unified. In 2025–2026, reported all-grades proficiency was 44% in English language arts (ELA), 33% in math and 42% in science. Among 11 nearby schools, Harry Dewey had the second-highest reported result in each subject, behind Cambridge Heights Elementary. The key takeaway is that Harry Dewey performs especially well compared with nearby schools, but its ELA and math results remain below the state.
Science is the school’s clearest strength against state and district results: 42% proficiency compares with 36% statewide and 31% districtwide. ELA was 44%, above the district’s 40% but below the state’s 49%; math was 33%, above the district’s 29% but below the state’s 38%. Results also vary sharply by grade. Fourth-grade ELA was 56%, the highest among nearby schools reporting results, and fourth-grade math was 50%, second to Cambridge Heights. Fifth-grade math, however, was 12%, below the nearby-school average of 17%, the district’s 24% and the state’s 37%. All-grades comparisons are not perfectly like for like because nearby schools have different grade spans.
