27 public K-12 schools in Flagstaff 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, Flagstaff has more public-school enrollment than 83% of the 4,487 US cities in this directory. Flagstaff'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.
15 of Flagstaff's 27 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.
8 of 27 listed Flagstaff campuses are reported as charters, so district-run and charter records occupy substantial shares of the same city view. They may follow different governance, enrollment, and program structures even when their mailing city matches. The 48-point gap between Summit High School and Ponderosa High School should be read within that context, not as a single-system league table. Check charter status and district affiliation before comparing two nearby schools, and verify current admissions rules with the operator.
Flagstaff school enrollment ranges from 2 students (lowest) to 1,631 students (highest), a spread of 1,629 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.

Each school district has independent budgeting, hiring, and service delivery authority, and the sheer count here puts it in the extreme tail of fragmentation nationally. The fragmentation reflects historical patterns of inter-municipal boundary lines that pre-date modern city growth, students in different parts of the same city can attend different districts with different per-pupil spending, calendars, and graduation requirements. Per-region variation is largest in fragmented systems because each school district sets its own budget, contracts, and priorities without higher-level coordination above the regulatory floor.

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 Flagstaff is typically wider than the Flagstaff-aggregate figure suggests.

30% of the city's listed public-school campuses are reported as charter schools in NCES CCD. Charter status identifies a different governance arrangement; it does not establish admissions availability, academic quality, or the share of city students enrolled in those campuses.

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.
