How One.Charter compares with California and U.S. medians
What stands out at One.Charter
One.Charter is a higher-need, large charter combined-grade school in Stockton, California, enrolling 1,356 students.
Class loads run heavy: 39.9:1 is larger than about 99% of California schools and 86% above the 21.5:1 state mean, so each teacher carries more students than is typical.
Economic need runs somewhat above the state's typical profile, with 66.9% of students eligible for free meals.
By headcount it is one of the larger campuses in California, bigger than 93% of state schools at 1,356 students.
Its Resource Investment Index trails 96% of the 9,998 California schools with a score on record, one of the lower results on this measure.
Among 490 similarly sized, similarly resourced-need California schools statewide, it ranks #462, in the lower tier once campus size and economic need are matched.
Its student body is led by Hispanic or Latino (64%) and African American (13%) (diversity index 56/100).
Counselor access is stretched at roughly 1356 students per counselor, well above the ASCA-recommended 250:1 ceiling.
Chronic absenteeism is elevated: 34.8% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
Among Stockton's public schools, it stands alongside Franklin High (2,065 students): One.Charter is smaller than that campus by headcount and runs heavier classes (39.9:1 vs 19.9:1).
One.Charter District is a single-school charter district, so One.Charter operates independently rather than alongside district-mates.
