What stands out at Rockwood Elementary
Rockwood Elementary is a high-poverty, mid-sized elementary school in Calexico, California, enrolling 617 students.
Class loads run heavy: 26.8:1 is larger than about 89% of California schools and 25% above the 21.5:1 state mean, so each teacher carries more students than is typical.
Economic need is high: 91.2% of students qualify for free meals, 64% above the California average, a Title I-weighted population that federal funding formulas prioritise.
Enrollment of 617 puts it in the larger third of California schools by headcount.
Its Resource Investment Index trails 100% of the 9,998 California schools with a score on record, one of the lower results on this measure.
Among 1,280 similarly sized, similarly resourced-need California schools statewide, it ranks #1,255, in the lower tier once campus size and economic need are matched.
Its student body is predominantly Hispanic or Latino (99% of enrollment), among the less diverse in the state (diversity index 3/100).
Counselor access is stretched at roughly 617 students per counselor, well above the ASCA-recommended 250:1 ceiling.
Chronic absenteeism is elevated: 78.1% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
Its district draws 20.4% of revenue from federal sources, an above-typical federal share that tends to track a higher-need student population.
Among Calexico's elementary schools, it stands alongside Cesar Chavez Elementary (765 students): Rockwood Elementary is smaller than that campus by headcount and runs heavier classes (26.8:1 vs 23.9:1).
