District-Level NCES Analysis

Cinnabar Elementary operates 2 public schools serving 207 students, placing it among the smallest districts in California. The school portfolio breaks down into 2 elementary 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 Sonoma County.

Per-pupil expenditure runs $17,108 according to the NCES F-33 School District Finance Survey, in the upper half of 1862 California districts by per-pupil spending. See how California compares in our national per-pupil spending analysis. The funding mix is 27.8% local, 65.1% state, and 7.0% 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 69/100, ranked #306 of 1517 in California against a state average of 50, notably more even than the typical district in the state for how evenly funding reaches its schools.

a 98.3:1 student-counselor ratio, that meets the ASCA-recommended benchmark, and 29.9% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 77.5% Hispanic or Latino, 17.4% White, 0.3% African American across the district's schools.

Its largest campus is Cinnabar Charter, enrolling 156 students (89% of the district's total enrollment). Its smallest is Cinnabar Elementary, at 20 students, a 8x enrollment spread across the district's campuses.

Cinnabar Charter accounts for 75.4% of all Cinnabar Elementary student enrollment

That is an overwhelming concentration, leaving the rest of Cinnabar Elementary a distant remainder — means Cinnabar 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.

Cinnabar Elementary has higher-than-average Title I eligibility — 65.5% 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). Eligibility here is approaching the 75% concentration-grant threshold; it does not yet unlock the extra funding tier but sits meaningfully above the baseline 50% majority mark. 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.

Cinnabar Elementary student-counselor ratio is 98:1 — 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.

Cinnabar Elementary chronic absenteeism rate is 29.9% — 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 Cinnabar Elementary is typically wider than the Cinnabar Elementary-aggregate figure suggests.
