Summary

Windsor Middle serves 736 students in grades 6–8 in Windsor, California. Its 2025–2026 proficiency results were above the reported all-grades rates for Windsor Unified in English language arts (ELA), math and science, but below state results in all three. The biggest concern is math: 29% of students were proficient, 9 percentage points below the state, and sixth-grade math was particularly weak, at 19%—19 points below the state.

Science is the school’s strongest subject compared with the state: 36% were proficient, essentially level with the state’s 36% and 4 points above the district’s 32%. Math was above the district’s 26%, but had the largest state gap; ELA was 42%, also below the state. Results vary by grade: seventh grade was much closer to state levels in ELA and math, with 47% and 36% proficient, respectively. In comparison, nearby Twin Hills Charter Middle reported higher all-grades proficiency in ELA (58%), math (55%) and science (54%).

Recent trends are mixed: from 2024–2025 to 2025–2026, science rose 5 points and ELA rose 1 point, while math fell 4 points. Over four years, math increased by less than 1 point while the state gained 4, widening the gap. SchoolDigger placed Windsor at the 48th percentile statewide with 2 stars in 2025–2026, down from the 59th percentile and 3 stars in 2023–2024; it ranked fifth among nine nearby schools with current rank histories. SchoolDigger’s subgroup rankings also show different results: the school ranked at the 31st percentile for how well it serves students with low socioeconomic status, down from the 60th percentile in 2023–2024, while its ranking for serving Special Education Students rose from the 20th to the 45th percentile in one year. Context includes a student-teacher ratio of 15.9 in 2024–2025, second-lowest among nearby schools with data, and 47% of students eligible for free/reduced lunch in 2024–2025.
