8 public K-12 schools in Annandale from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
According to NCES CCD 2024-25, Annandale has more public-school enrollment than 70% of the 4,487 US cities in this directory. Annandale 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.
Combined-grade campuses shape the local portfolio
6 of Annandale's 8 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
Annandale's schools share one district authority while their average Resource Investment Index ranks at the 89th 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 21-point gap between Columbia Elementary and Annandale 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.

Annandale High accounts for 30.6% of all Annandale public-school enrollment
That dominant concentration means Annandale-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.
Annandale school enrollment varies 5.7× across entities
Annandale school enrollment ranges from 377 students (lowest) to 2,161 students (highest), a spread of 1,784 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.
The reported share clears the 50% majority mark. Title I operates under the Every Student Succeeds Act (ESSA, 2015), but its statutory allocation uses additional LEA-level counts and rules not represented by this average. This percentage is an economic-need context measure; it does not establish a Title I award, show dollars received, or describe how funds are distributed among campuses.
Annandale operates one school district — a single-district system
Annandale'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.
Annandale student-teacher ratio is 14.2:1 — 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 Annandale is typically wider than the Annandale-aggregate figure suggests.
Most racially and ethnically mixed schools in Annandale
Ranked by the Simpson student-body diversity index (0-100) from NCES race and ethnicity data, where higher means a more evenly mixed student body. It measures mix, not quality.
Which Annandale school has the highest Resource Investment Index? ▼

How many schools are in Annandale, VA? ▼
Annandale has 8 public schools with a total enrollment of 7,073 students. Average student-teacher ratio: 14.2:1.
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. See the guide to understanding NCES data.
