National city placement
Middle-of-corpus city profile
According to NCES CCD 2024-25, Romeoville has more public-school enrollment than 60% of the 4,487 US cities in this directory. Romeoville sits in the broad middle of the national city distribution rather than at a single obvious extreme. Its scale, average Resource Investment Index, and staffing position need to be read together: a middle placement on one measure does not cancel a stronger or weaker result on another. The percentile panel makes those dimensions explicit, and the school table shows where the city aggregate breaks into materially different campus profiles.
A full K–12 ladder sits inside the city boundary
Romeoville's list includes 3 elementary, 2 middle, and 1 high-school campus, 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.
The composite and staffing measures point in different directions
Romeoville's average Resource Investment Index sits at the 34th percentile, while its teacher-staffing measure sits at the 81st percentile. The 47-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.
