That dominant concentration means Thermalito Union Elementary-wide averages can mask substantial variation outside the dominant entity. Grade band: middle. 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.

Thermalito Union Elementary has higher-than-average Title I eligibility — 77.8% 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 — including this one — 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.

Thermalito Union Elementary student-counselor ratio is 251:1 — near the typical range (US average ~408) — within the typical range for U.S. public districts

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

Thermalito Union Elementary chronic absenteeism rate is 39.1% — 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.
