District-Level NCES Analysis
San Marino Unified operates 4 public schools serving 2,751 students, placing it among the smallest districts in California. The school portfolio breaks down into 2 elementary, 1 high, 1 middle schools, a small enough portfolio that most families will interact with nearly every campus in the district at some point. These enrollment and school figures come from the NCES Common Core of Data (CCD) 2024-25 release, and the district is based in Los Angeles County.
Per-pupil expenditure runs $15,051 according to the NCES F-33 School District Finance Survey, in the lower half of 1862 California districts by per-pupil spending. See how California compares in our national per-pupil spending analysis. The funding mix is 63.7% local, 28.4% state, and 7.9% federal, a local-revenue-heavy mix that leaves the district more exposed to property-tax swings and local ballot measures than state-funded peers. The district's equity score is 25/100, ranked #1347 of 1517 in California against a state average of 50, notably less even than the typical district in the state for how evenly funding reaches its schools.
Academic infrastructure includes 1 of 4 schools offering Advanced Placement (16 AP courses district-wide), a 976.6:1 student-counselor ratio, above both the ASCA benchmark and the roughly 408:1 national average, and 3.5% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 63.4% Asian, 16.8% White, 7.2% Hispanic or Latino across the district's schools. Its most demographically mixed campus is San Marino High, with a diversity index of 58.0/100.
Its largest campus is San Marino High, enrolling 886 students (29% of the district's total enrollment).
San Marino High accounts for 28.7% of all San Marino Unified student enrollment
That dominant concentration means San Marino Unified-wide averages can mask substantial variation outside the dominant entity. Grade band: high. A single dominant campus often anchors a district's program offerings and staffing patterns; the share helps explain why district-wide averages may not reflect the typical neighbourhood-school experience. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.
San Marino Unified student-counselor ratio is 977:1 — well above typical (typically associated with unusually large scale or acute resource constraints)
student-counselor ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE counselors against total enrollment, districts that contract intervention or social-emotional staff outside the counselor classification may be under-counted Values this far above typical often signal acute resource constraints or a structurally different scale than most peers — worth reading alongside the underlying counts, not the ratio alone.
San Marino Unified chronic absenteeism rate is 3.5% — well below typical (typically associated with unusually small scale or exceptionally high per-unit investment)
chronic absenteeism rate is the simplest comparative metric but it does not capture the full picture: a student is chronically absent if they miss ≥10% of enrolled days for any reason, illness, family obligations, or disengagement Values this far below typical often correlate with unusually small scale or population characteristics rather than higher resource budgets per se — worth checking whether the underlying denominator is itself an outlier.
San Marino Unified has 4 schools, including 1 high, 2 elementary, 1 middle. Total enrollment is 2,751 students.
