How San Antonio Elementary compares with California and U.S. medians
What stands out at San Antonio Elementary
San Antonio Elementary is a high-poverty, mid-sized elementary school in Pomona, California, enrolling 371 students.
Class loads run heavy: 26.5:1 is larger than about 87% of California schools and 23% above the 21.5:1 state mean, so each teacher carries more students than is typical.
Economic need is high: 90.3% of students qualify for free meals, 63% above the California average, a Title I-weighted population that federal funding formulas prioritise.
With 371 students, its enrollment sits close to the California median campus size.
Its Resource Investment Index trails 93% of the 9,998 California schools with a score on record, one of the lower results on this measure.
Among 1,133 similarly sized, similarly resourced-need California schools statewide, it ranks #1,016, in the lower tier once campus size and economic need are matched.
Counselor availability sits well past the ASCA benchmark, roughly 371 students sharing each counselor, though short of the most stretched campuses.
Chronic absenteeism is elevated: 50.7% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
Its district draws 17.6% of revenue from federal sources, an above-typical federal share that tends to track a higher-need student population.
Among Pomona's elementary schools, it stands alongside Vejar Elementary (741 students): San Antonio Elementary is smaller than that campus by headcount and runs heavier classes (26.5:1 vs 20.6:1).
Pomona Unified also operates Garey High (1,567 students) and Diamond Ranch High (1,542 students) alongside San Antonio Elementary.
