What other rankings don't show you
Most rating sites report "50% proficient" for Rio Americano High and stop there. Here's what that number hides:
22.1% of students exceeded standard while 27.6% met it. That exceeded rate is 6.6 points above the state average of 15.5%. That's 8.2 points above the San Juan Unified district average of 13.9%. Compared to the 4 nearby schools within ~3 miles, this exceeded rate is 15.2 points higher (vs 6.9% average). The gap between "met" and "exceeded" can reveal how much a school's curriculum challenges students beyond proficiency.
The graduation rate is 95.2% — above the state target. 56.2% of students complete A-G requirements for UC/CSU eligibility — a strong college readiness signal. 89.0% of graduates go on to college within a year.
Chronic absenteeism is 21.7%, better than the state average of 34.0%.
