See how California compares in our national per-pupil spending analysis. The funding mix is 11.5% local, 75.0% state, and 13.5% 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 77/100, ranked #128 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 552.6:1 student-counselor ratio, above both the ASCA benchmark and the roughly 408:1 national average, and 31.1% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 87.9% Hispanic or Latino, 3.5% African American, 3.4% White across the district's schools. Its most demographically mixed campus is Edison Elementary, with a diversity index of 39.8/100.
Its largest campus is Central Language Academy, enrolling 736 students (4% of the district's total enrollment). Its smallest is Online Academy, at 125 students, a 6x enrollment spread across the district's campuses.
Ontario-Montclair school enrollment varies 5.9× across entities
Ontario-Montclair school enrollment ranges from 125 students (lowest) to 736 students (highest), a spread of 611 students. That relatively narrow ratio reflects an unusually homogeneous campus portfolio, most districts have a wider mix of school sizes. Per-school staffing ratios, programme availability, and capital-renovation cycles often diverge inside the same district based on enrollment shape.
Ontario-Montclair has higher-than-average Title I eligibility — 70.8% 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). 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.
Ontario-Montclair student-counselor ratio is 553:1 — 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.
Ontario-Montclair chronic absenteeism rate is 31.1% — 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.
