25 public K-12 schools in Ashburn from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
National city placement
According to NCES CCD 2024-25, Ashburn has more public-school enrollment than 94% of the 4,487 US cities in this directory. Ashburn lands in the upper national tier on both the average Resource Investment Index and teacher staffing intensity. Those measures come from different inputs: the index combines reported counselors, gifted access, attendance, and staffing, while the staffing percentile compares the city's student-teacher ratio directly. Agreement across both measures is stronger evidence of broad reported capacity than either score alone, though neither is a test-score rating or a guarantee about an individual classroom.
16 of Ashburn's 25 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.
Ashburn's schools share one district authority while their average Resource Investment Index ranks at the 95th 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 24-point gap between Brambleton Middle and Rock Ridge 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.
Ashburn school enrollment ranges from 503 students (lowest) to 2,166 students (highest), a spread of 1,663 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.

Ashburn's listed schools share one district boundary, budget authority, and reporting chain. That makes citywide and districtwide governance easier to compare, but it does not make individual campuses uniform: grade configuration, staffing, programs, and student need can still vary materially within the same school district.

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 Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.

Data from NCES Common Core of Data (CCD) 2024-25 and Civil Rights Data Collection (CRDC) 2021-22. The Resource Investment Index uses reported student-teacher ratio, counselor access, gifted programs, and attendance; it is not an academic rating. Cities must include at least five schools to be listed. This public-data comparison is for informational purposes: verify current enrollment, attendance boundaries, and programs with the school district before acting.
