What other rankings don't show you

Most rating sites report "72% proficient" for Mira Costa High and stop there. Here's what that number hides:

42.7% of students exceeded standard while 28.9% merely met it. That exceeded rate is 27.2 points above the state average of 15.5%. That's 15.2 points below the Manhattan Beach Unified district average of 57.9%. Compared to the 6 nearby schools within ~3 miles, this exceeded rate is 26.7 points higher (vs 16.0% 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 98.7% — above the state target. 84.3% of students complete A-G requirements for UC/CSU eligibility — a strong college readiness signal. 91.1% of graduates go on to college within a year.

Chronic absenteeism is 14.7%, better than the state average of 34.0%.
