Class loads run heavy: 32.2:1 is larger than about 97% of California schools and 50% above the 21.5:1 state mean, so each teacher carries more students than is typical.

With 418 students, its enrollment sits close to the California median campus size.

Its student body is led by Hispanic or Latino (60%) and White (15%) (diversity index 60/100).

Counselor access is stretched at roughly 523 students per counselor, well above the ASCA-recommended 250:1 ceiling.
