7 public K-12 schools in Windsor from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
According to NCES CCD 2024-25, Windsor has more public-school enrollment than 46% of the 4,487 US cities in this directory. Windsor High enrolls 41.2% of Windsor's public-school students. That is enough concentration for one institution to pull the citywide enrollment, staffing, and Resource Index averages toward its own profile. The smaller campuses below should therefore be compared directly rather than inferred from the headline mean; their grade configurations and program footprints can be materially different even inside the same district.
A full K–12 ladder sits inside the city boundary
Windsor's list includes 2 elementary, 1 middle, and 2 high-school campuses, plus 2 combined-grade records. The city average spans every major grade stage, so the ranked table is more informative when read within level than as one interchangeable queue.
A small portfolio contains radically different campus scales
Windsor lists only 7 schools, yet reported enrollment runs from 33 to 1,700 students, a 52-fold range. In a portfolio this compact, the smallest record may be a specialized or nonstandard setting rather than a miniature version of the largest campus. That distinction affects how ratios and program fields should be read. Compare similarly configured grade levels first; combining the extremes into one city average conceals more than it explains.

Windsor High accounts for 41.2% of all Windsor public-school enrollment
That dominant concentration means Windsor-wide averages can mask substantial variation outside the largest entity. Grade level: High. The share measures enrollment concentration only; it does not establish how districts allocate programs, capital, or staff. Enrollment-weighted aggregates give this entity more weight than any smaller peer, while an unweighted entity average treats every record equally.
Windsor school enrollment varies 52× across entities
Windsor school enrollment ranges from 33 students (lowest) to 1,700 students (highest), a spread of 1,667 students. That ratio is among the widest observed and reflects extreme heterogeneity inside a single city, with small specialty programs listed alongside large comprehensive campuses. Per-school staffing and program breadth can differ sharply at opposite ends of that enrollment range, so the city average should not be treated as a typical campus.
Windsor operates one school district — a single-district system
Windsor's listed schools share one district boundary, budget authority, and reporting chain. That makes citywide and districtwide governance easier to compare, but it does not make individual campuses uniform: grade configuration, staffing, programs, and student need can still vary materially within the same school district.
Windsor student-teacher ratio is 16.1:1 — near the typical range (US average ~15.7) — citywide staffing is neither unusually lean nor unusually crowded by this measure
student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment, push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Variation between sub-units within Windsor is typically wider than the Windsor-aggregate figure suggests.
14% of the city's listed public-school campuses are reported as charter schools in NCES CCD. Charter status identifies a different governance arrangement; it does not establish admissions availability, academic quality, or the share of city students enrolled in those campuses.

Most racially and ethnically mixed schools in Windsor
Ranked by the Simpson student-body diversity index (0-100) from NCES race and ethnicity data, where higher means a more evenly mixed student body. It measures mix, not quality.
Which Windsor school has the highest Resource Investment Index? ▼

How many schools are in Windsor, CA? ▼
Windsor has 7 public schools with a total enrollment of 4,123 students. 1 are charter schools. Average student-teacher ratio: 16.1:1.
Data from NCES Common Core of Data (CCD) 2024-25 and Civil Rights Data Collection (CRDC) 2021-22. The Resource Investment Index uses reported student-teacher ratio,
counselor access, gifted programs, and attendance; it is not an academic rating. Cities must include at least five schools to be listed. This public-data comparison is for informational purposes:
verify current enrollment, attendance boundaries, and programs with the school district before acting. See the guide to understanding NCES data.
