What other rankings don't show you
Most rating sites report "74% proficient" for Mountain House High and stop there. Here's what that number hides:
47.5% of students exceeded standard while 26.2% met it. That exceeded rate is 32.0 points above the state average of 15.5%. That's 2.3 points above the Lammersville Joint Unified district average of 45.2%. The gap between "met" and "exceeded" can reveal how much a school's curriculum challenges students beyond proficiency.
The graduation rate is 99.0% — above the state target. 69.8% of students complete A-G requirements for UC/CSU eligibility — a strong college readiness signal. 83.2% of graduates go on to college within a year.
Chronic absenteeism is 9.0%, better than the state average of 34.0%.
