District-Level NCES Analysis
River Delta Joint Unified operates 10 public schools serving 1,787 students, placing it among the smaller districts in California. The school portfolio breaks down into 4 elementary, 3 high, 2 combined, 1 middle schools, a compact enough portfolio that families can compare every campus directly before they move, rent, or enrol. These enrollment and school figures come from the NCES Common Core of Data (CCD) 2024-25 release, and the district is based in Solano County.
Per-pupil expenditure runs $13,859 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 50.1% local, 41.9% state, and 8.0% 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 43/100, ranked #937 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.
Academic infrastructure includes 2 of 10 schools offering Advanced Placement (17 AP courses district-wide), a 407.6:1 student-counselor ratio, well above the ASCA benchmark though still under the roughly 408:1 national average, and 44.7% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 57.9% Hispanic or Latino, 32.6% White, 1.8% African American across the district's schools. Its most demographically mixed campus is D. H. White Elementary, with a diversity index of 66.1/100.
Its largest campus is D. H. White Elementary, enrolling 432 students (25% of the district's total enrollment). Its smallest is Mokelumne High (Continuation), at 8 students, a 54x enrollment spread across the district's campuses.
D. H. White Elementary accounts for 24.2% of all River Delta Joint Unified student enrollment
That concentration means River Delta Joint Unified-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.
River Delta Joint Unified school enrollment varies 54× across entities
River Delta Joint Unified school enrollment ranges from 8 students (lowest) to 432 students (highest), a spread of 424 students. That ratio is among the widest observed and reflects extreme enrollment heterogeneity, the district operates both small specialty programs and large comprehensive campuses inside a single budgeting unit. Per-school staffing ratios, programme availability, and capital-renovation cycles often diverge inside the same district based on enrollment shape.
River Delta Joint Unified has higher-than-average Title I eligibility — 54.6% 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.
River Delta Joint Unified student-counselor ratio is 408:1 — high (typically associated with staffing constraints that limit per-student counselor time; CRDC data shows higher ratios cluster in larger urban systems)
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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
River Delta Joint Unified chronic absenteeism rate is 44.7% — well above typical (typically associated with unusually large scale or acute resource constraints)
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 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.
