National city placement
One campus shapes the city average
According to NCES CCD 2024-25, Riverside has more public-school enrollment than 34% of the 4,487 US cities in this directory. Riverside Brookfield Twp Hs enrolls 49.7% of Riverside'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.
Combined-grade campuses shape the local portfolio
3 of Riverside's 5 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.
The composite and staffing measures point in different directions
Riverside's average Resource Investment Index sits at the 97th percentile, while its teacher-staffing measure sits at the 62nd percentile. The 35-point percentile gap is a reminder that the index is not a class-size score: counselors, gifted-program reporting, and attendance also affect it. Compare those components directly when two schools have similar index totals; the same headline score can arise from a different mix of reported resources.
