6 public K-12 schools in Greendale 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, Greendale has more public-school enrollment than 22% of the 4,487 US cities in this directory. Greendale's 6 listed schools all sit inside one district, creating a compact governance structure with one budget, board, and reporting chain. That makes citywide comparisons cleaner than in places split across several districts, but it does not make the campuses interchangeable: elementary, middle, and high-school staffing needs differ. The ranked list is best read as variation inside one system rather than competition among separate local authorities.
Combined-grade campuses shape the local portfolio
3 of Greendale's 6 listed schools use NCES's combined or “other” grade-level classification. Citywide averages therefore blend campuses serving unusually broad or nonstandard grade spans with conventional elementary, middle, and high schools. Grade configuration is a first-order comparison here, not a minor label.
A small portfolio contains radically different campus scales
Greendale lists only 6 schools, yet reported enrollment runs from 88 to 882 students, a 10-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.

Greendale High accounts for 34.6% of all Greendale public-school enrollment
That dominant concentration means Greendale-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.
Greendale school enrollment varies 10× across entities
Greendale school enrollment ranges from 88 students (lowest) to 882 students (highest), a spread of 794 students. That spread reflects typical urban portfolio variation between specialty programs and large neighbourhood schools. 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.
Greendale operates one school district — a single-district system
Greendale'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.
Greendale student-teacher ratio is 14.0:1 — 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 Greendale is typically wider than the Greendale-aggregate figure suggests.
17% 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 Greendale
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 Greendale school has the highest Resource Investment Index? ▼
College Park Elementary has the highest Resource Investment Index among the Greendale schools in this federal-data comparison at 74/100. The index summarizes reported staffing, counseling, gifted-program, and attendance inputs; it is not an academic rating.
How many schools are in Greendale, WI? ▼
Greendale has 6 public schools with a total enrollment of 2,546 students. 1 are charter schools. Average student-teacher ratio: 14:1.
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.
