National city placement
Compact, single-district system
According to NCES CCD 2024-25, Harker Heights has more public-school enrollment than 69% of the 4,487 US cities in this directory. Harker Heights's 7 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 Harker Heights's 7 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.
Campus spread matters more than the city mean
The 14-point gap between Union Grove Middle and Harker Heights H S shows the range hidden by Harker Heights's average Resource Investment Index. The city figure is useful for national placement, but families ultimately choose among campuses with different grade spans, enrollment, district affiliations, and reported support fields. Start with schools serving the relevant grade level, then compare the index components rather than assuming the city average describes any one classroom.
