National city placement
Middle-of-corpus city profile
According to NCES CCD 2024-25, Potomac has more public-school enrollment than 67% of the 4,487 US cities in this directory. Potomac 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
Potomac's list includes 2 elementary, 2 middle, and 1 high-school campus, plus 3 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.
One district, but meaningful resource variation
Potomac's schools share one district authority while their average Resource Investment Index ranks at the 92nd 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 16-point gap between Cabin John Middle and Potomac Elementary 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.
