Summary:
Zip code 95492 has seven schools serving elementary through high school grades, all part of Windsor Unified. Across schools with published results, average proficiency in 2025–2026 was 32% in English Language Arts (ELA), 21% in math and 31% in science, all below California averages. The clearest area-wide concern is that local ELA and math results fell while state results rose: the ELA average dropped from 39% to 32%, and the math average from 27% to 21%, widening the gaps with California to 18 points in both subjects.
Windsor High stands out in ELA, with 59% proficient—17 points above the next-highest reported school, Windsor Middle, and 9 points above the state. But Windsor High’s math result was 23%, well below the state’s 38%. Windsor Middle led in math at 29%, just 2 points ahead of Cali Calmecac Language Academy; it also led in science at 36%, nearly matching the state. At the low end, Windsor Oaks Academy reported 0% in ELA and 7% in math. Brooks Elementary had the lowest numeric science result, 27%, 9 points below California.
Trends differ by school: Sonoma County Virtual Academy fell 27 points in ELA and 18 in math between 2024–2025 and 2025–2026, while Cali Calmecac’s science result rose 13 points. SchoolDigger rankings also declined over the listed recent years at Windsor Middle, from percentile 59 to 48, and Brooks, from 37 to 22; Cali Calmecac remained nearly steady at 27, 26 and 27. As additional context, all schools report free/reduced lunch eligible figures for 2024–2025, ranging from 38% at Big Picture Learning Windsor to 70% at Windsor Oaks; these figures do not explain test results. Big Picture’s test results are suppressed, and Windsor Oaks’ low proficiency coincides with 90% chronic absenteeism, compared with 18% statewide. Because schools serve different grades, all-grades comparisons do not tell the whole story.
