How Siatech compares with California and U.S. medians
What stands out at Siatech
Siatech is a high-poverty, large charter high school in Oceanside, California, enrolling 1,174 students.
Class loads run heavy: 26.7:1 is larger than about 88% of California schools and 24% above the 21.5:1 state mean, so each teacher carries more students than is typical.
Economic need is high: 86.5% of students qualify for free meals, 56% above the California average, a Title I-weighted population that federal funding formulas prioritise.
By headcount it is one of the larger campuses in California, bigger than 91% of state schools at 1,174 students.
Its Resource Investment Index lands in the lower third of 9,998 scored California schools.
Among 462 similarly sized, similarly resourced-need California schools statewide, it ranks #344, in the lower tier once campus size and economic need are matched.
Its student body is led by Hispanic or Latino (69%) and African American (13%) (diversity index 49/100).
No Advanced Placement courses are reported for this campus in the federal data.
Counselor coverage runs a bit thin, about 294 students per counselor, somewhat past the ASCA-recommended 250:1 benchmark.
Chronic absenteeism is elevated: 36.2% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
The surrounding Siatech District spends $30,194 per pupil, 83% above the California average, a better-resourced district than most.

Siatech District is a single-school charter district, so Siatech operates independently rather than alongside district-mates.
