Lean reported-resource profile

According to NCES CCD 2024-25, Arlington has more public-school enrollment than 68% of the 4,487 US cities in this directory. Arlington's average Resource Investment Index falls in the lower portion of the 4,487-city comparison set. The index is a resource snapshot, not an academic grade: it reflects the federal staffing, counselor, gifted-program, and attendance fields available for local campuses. The most useful next step is to open the individual schools below and identify which component is pulling each score down, because the same city average can hide very different campus-level constraints.

Secondary campuses occupy an unusually large share

5 of the 13 listed Arlington schools are classified as high schools, a substantial share of the local portfolio. Advanced-course access, counseling, and graduation-stage staffing therefore have more weight in the city Resource Index average than they do in an elementary-heavy system.

Campus spread matters more than the city mean

The 15-point gap between Weston High School and Arlington Open Doors shows the range hidden by Arlington'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.

Arlington High School accounts for 24.1% of all Arlington public-school enrollment

That concentration means Arlington-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.

Arlington school enrollment varies 825× across entities

Arlington school enrollment ranges from 2 students (lowest) to 1,650 students (highest), a spread of 1,648 students. That ratio is an extreme outlier spread — among the widest gaps observed anywhere in this dataset. 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.

Arlington student-teacher ratio is 18.6:1 — high (typically associated with larger urban scale or staffing constraints that have widened the headcount gap)

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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.

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.
