15 public K-12 schools in National City 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, National City has more public-school enrollment than 82% of the 4,487 US cities in this directory. National City'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.
The school portfolio is elementary-weighted
11 of National City's 15 listed schools are elementary campuses. That composition means citywide enrollment and staffing averages are influenced more by early-grade operating patterns than by the city's 1 middle and 2 high-school records. Families comparing later grades should rely on those individual rows rather than the all-school mean.
High measured need meets a thin staffing ratio
National City's reporting schools show 72.8% free-lunch eligibility across measured enrollment, alongside an average 21.8:1 student-teacher ratio. These are separate constraints: one describes the economic context of enrolled students and the other compares student and teacher headcounts. The 27-point gap between Granger Junior High and San Diego Workforce Innovation High is therefore more useful than the city mean alone. A school with a similar ratio may still report different counselor access, attendance, or gifted-program availability, so open the campus records before drawing conclusions about student support.

San Diego Workforce Innovation High accounts for 25.2% of all National City public-school enrollment
That concentration means National City-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.
National City school enrollment varies 8.5× across entities
National City school enrollment ranges from 322 students (lowest) to 2,722 students (highest), a spread of 2,400 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.
National City reports 72.8% free-lunch eligibility
The reported share sits between 62.5% and 75%, above a simple majority but below the highest descriptive band used here. 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.
National City student-teacher ratio is 21.8:1 — 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.
2 of National City's 15 listed schools are charters
13% 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. Open each school record to compare enrollment and staffing directly.
Most racially and ethnically mixed schools in National City
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.

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.
