Summary:
ZIP code 95623 has one elementary school, Charles F. Brown Elementary, serving grades 2–6, with 85 students reported in 2024–2025. In 2025–2026, its all-grades proficiency was 46% in ELA, 40% in math and 29% in science, compared with California’s 49%, 38% and 36%. The clearest takeaway is that math was the school’s only all-grades subject above the state result, by 2 percentage points.
There is no local school-to-school ranking: as the only school in the ZIP, Charles F. Brown is both highest and lowest by definition. Compared with the Mother Lode Union Elementary district, the school was ahead by 8 points in ELA and 15 in math, but behind by 3 in science. Fifth grade was a standout: ELA proficiency was 69%, 20 points above the state result for that grade, and math was 53%, 16 points above; fifth-grade science, at 29%, was 6 points below the state.
Results moved in different directions over the two reported years: math rose 11 points, from 29% to 40%, while California math rose 1 point; science fell 9 points, from 39% to 29%, even as the state gained 3 points. ELA improved by 3 points to 46%, narrowing the school’s gap with the state. SchoolDigger’s statewide percentile rose from 36 in 2023–2024 to 54 in 2025–2026, and its rating moved from 2 stars to 3. The reported student–teacher ratio was 17:1, and 61% of students were free/reduced lunch eligible in 2024–2025. These figures offer context, not an explanation for academic results; with one school and only two years of test trends, the data cannot show local school-to-school differences or establish a lasting trend.
