The funding mix is 69.7% local, 19.6% state, and 10.7% federal, a local-revenue-heavy mix that leaves the district more exposed to property-tax swings and local ballot measures than state-funded peers.

a 105:1 student-counselor ratio, that meets the ASCA-recommended benchmark, and 38.9% chronic absenteeism from the 2021-22 Civil Rights Data Collection.

That is an overwhelming concentration, leaving the rest of San Mateo County Office of Education a distant remainder — means San Mateo County Office of Education-wide averages can mask substantial variation outside the dominant entity. Grade band: combined. 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 Mateo County Office of Education student-counselor ratio is 105:1 — well below typical (typically associated with unusually small scale or exceptionally high per-unit investment)

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 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 Mateo County Office of Education chronic absenteeism rate is 38.9% — high (typically associated with higher-than-average disruption; recent CRDC data showed elevated rates persisting after pandemic-era schooling changes)

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