33 public K-12 schools in Santa Barbara 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, Santa Barbara has more public-school enrollment than 87% of the 4,487 US cities in this directory. Santa Barbara's average Resource Investment Index ranks above most listed cities even though its student-teacher ratio is on the more crowded side of the national city distribution. That is a useful mismatch, not a contradiction: counselor access, gifted programs, and attendance can lift the composite while classroom staffing remains comparatively tight. Families should inspect the component scores on each school profile instead of reading the city index as a shorthand for small classes.
The school portfolio is elementary-weighted
20 of Santa Barbara's 33 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 4 middle and 4 high-school records. Families comparing later grades should rely on those individual rows rather than the all-school mean.
The composite and staffing measures point in different directions
Santa Barbara's average Resource Investment Index sits at the 69th percentile, while its teacher-staffing measure sits at the 34th percentile. The 35-point percentile gap is a reminder that the index is not a class-size score: counselors, gifted-program reporting, and attendance also affect it. Compare those components directly when two schools have similar index totals; the same headline score can arise from a different mix of reported resources.

Santa Barbara school enrollment varies 963× across entities
Santa Barbara school enrollment ranges from 2 students (lowest) to 1,926 students (highest), a spread of 1,924 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.
Santa Barbara operates 10 school districts — one of the single most fragmented governance structures in the country
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.
Santa Barbara student-teacher ratio is 16.9:1 — 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 Santa Barbara is typically wider than the Santa Barbara-aggregate figure suggests.
4 of Santa Barbara's 33 listed schools are charters
12% 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.
