National city placement

Middle-of-corpus city profile

According to NCES CCD 2024-25, Chantilly has more public-school enrollment than 80% of the 4,487 US cities in this directory. Chantilly 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.

The listed grade span is structurally narrow

Chantilly's 7 listed schools do not form a conventional mix of elementary, middle, and high-school campuses. The missing or thin grade bands make all-school city averages less representative of a typical K–12 pathway; district boundaries and nearby-city options may matter more for the grades not well represented here.

Campus spread matters more than the city mean

The 20-point gap between Rocky Run Middle and Westfield High shows the range hidden by Chantilly'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.

Chantilly High accounts for 29.7% of all Chantilly public-school enrollment

That dominant concentration means Chantilly-wide averages can mask substantial variation outside the largest entity. Grade level: High. The share measures enrollment concentration only; it does not establish how districts allocate programs, capital, or staff. Enrollment-weighted aggregates give this entity more weight than any smaller peer, while an unweighted entity average treats every record equally.

Chantilly school enrollment varies 4.3× across entities

Chantilly school enrollment ranges from 683 students (lowest) to 2,937 students (highest), a spread of 2,254 students. That relatively narrow ratio reflects an unusually homogeneous school portfolio for a city this size. Per-school staffing and program breadth can differ sharply at opposite ends of that enrollment range, so the city average should not be treated as a typical campus.

Chantilly student-teacher ratio is 14.6:1 — near the typical range (US average ~15.7) — citywide staffing is neither unusually lean nor unusually crowded by this measure

student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment, push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Variation between sub-units within Chantilly is typically wider than the Chantilly-aggregate figure suggests.
