National city placement
Middle-of-corpus city profile
According to NCES CCD 2024-25, Dumfries has more public-school enrollment than 79% of the 4,487 US cities in this directory. Dumfries 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.
Combined-grade campuses shape the local portfolio
7 of Dumfries's 10 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.
One district, but meaningful resource variation
Dumfries's schools share one district authority while their average Resource Investment Index ranks at the 83rd percentile among listed cities. Shared governance removes one source of policy variation, but it does not erase campus differences by grade span or enrollment. The 27-point gap between Montclair Elementary and Potomac High measures the remaining local spread. Use the district-level picture for common budget context, then compare the school components to see whether staffing, counseling, gifted-program reporting, or attendance accounts for each campus's position.
