National city placement
One campus shapes the city average
According to NCES CCD 2024-25, Vandalia has more public-school enrollment than 18% of the 4,487 US cities in this directory. Butler High School enrolls 36.6% of Vandalia'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.
A full K–12 ladder sits inside the city boundary
Vandalia's list includes 2 elementary, 1 middle, and 1 high-school campus, plus 1 combined-grade record. 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
Vandalia's average Resource Investment Index sits at the 55th percentile, while its teacher-staffing measure sits at the 16th percentile. The 39-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.
