What other rankings don't show you

Most rating sites report "81% proficient" for San Marino High and stop there. Here's what that number hides:

49.8% of students exceeded standard while 31.4% merely met it. That exceeded rate is 34.3 points above the state average of 15.5%. That's 11.2 points below the San Marino Unified district average of 61.0%. Compared to the 6 nearby schools within ~3 miles, this exceeded rate is 30.5 points higher (vs 19.3% average). The gap between "met" and "exceeded" is the difference between a school that clears the bar and one that raises it.

The graduation rate is 97.1% — above the state target. 85.7% of students complete A-G requirements for UC/CSU eligibility — a strong college readiness signal. 93.7% of graduates go on to college within a year.

Chronic absenteeism is 0.7%, better than the state average of 34.0%.
