How Isana Achernar Academy compares with California and U.S. medians
What stands out at Isana Achernar Academy
Isana Achernar Academy is a high-poverty, mid-sized charter elementary school in Compton, California, enrolling 407 students.
At 22.6:1, its student-teacher ratio sits close to the California median, within a few percentage points of the 21.5:1 state norm, neither notably crowded nor notably small.
Economic need is high: 84.8% of students qualify for free meals, 53% above the California average, a Title I-weighted population that federal funding formulas prioritise.
With 407 students, its enrollment sits close to the California median campus size.
Its Resource Investment Index lands in the lower third of 9,998 scored California schools.
Among 1,650 similarly sized, similarly resourced-need California schools statewide, it ranks #1,310, in the lower tier once campus size and economic need are matched.
Its student body is led by Hispanic or Latino (67%) and African American (31%) (diversity index 46/100).
Counselor access is stretched at roughly 407 students per counselor, well above the ASCA-recommended 250:1 ceiling.
Chronic absenteeism is elevated: 33.7% 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 Compton's elementary schools, it stands alongside Clinton William Jefferson (692 students): Isana Achernar Academy is smaller than that campus by headcount and runs leaner classes (22.6:1 vs 23.9:1).
Isana Achernar Academy District is a single-school charter district, so Isana Achernar Academy operates independently rather than alongside district-mates.
