See how California compares in our national per-pupil spending analysis. The funding mix is 32.2% local, 57.4% state, and 10.3% federal, a state-revenue-heavy mix that insulates the district somewhat from local property-tax volatility, though it ties funding to state budget cycles. The district's equity score is 47/100, ranked #836 of 1517 in California against a state average of 50, in line with the typical spread seen across the state for how evenly funding reaches its schools.

a 627.4:1 student-counselor ratio, above both the ASCA benchmark and the roughly 408:1 national average, and 28.0% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 87.2% Hispanic or Latino, 4.5% Asian, 4.4% White across the district's schools. Its most demographically mixed campus is Rio Del Sol, with a diversity index of 52.4/100.

Its largest campus is Rio Del Sol, enrolling 839 students (16% of the district's total enrollment).

Rio Del Sol accounts for 16.0% of all Rio Elementary student enrollment

That concentration means Rio Elementary-wide averages can mask substantial variation outside the dominant entity. Grade band: elementary. 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.

Rio Elementary school enrollment varies 2.1× across entities

Rio Elementary school enrollment ranges from 405 students (lowest) to 839 students (highest), a spread of 434 students.

Rio Elementary has higher-than-average Title I eligibility — 54.8% of the population qualifies for free or reduced-price lunch

free or reduced-price lunch eligibility is the federal threshold for Title I funding allocations, established under the Every Student Succeeds Act (ESSA, 2015). Areas above 75% eligibility receive concentration grants on top of the basic Title I formula. Regions with eligibility this high typically draw a substantially larger federal funding share relative to their local tax base, which can either offset or reinforce existing gaps depending on allocation policy.

Rio Elementary student-counselor ratio is 627:1 — 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.

Rio Elementary chronic absenteeism rate is 28.0% — near the typical range (US average ~28) — aligned with the national post-pandemic baseline of roughly 28% chronic absenteeism

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 Variation between sub-units within Rio Elementary is typically wider than the Rio Elementary-aggregate figure suggests.
