National city placement
One campus shapes the city average
According to NCES CCD 2024-25, San Tan Vly has more public-school enrollment than 1% of the 4,487 US cities in this directory. Early Childhood Learning Center enrolls 48.8% of San Tan Vly'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 San Tan Vly'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.
A small portfolio contains radically different campus scales
San Tan Vly lists only 5 schools, yet reported enrollment runs from 3 to 164 students, a 55-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.
