What other rankings don't show you

Most rating sites report "48% proficient" for Centennial High and stop there. Here's what that number hides:

20.5% of students exceeded standard while 27.8% met it. That exceeded rate is 5.0 points above the state average of 15.5%. That's 2.2 points below the Corona-Norco Unified district average of 22.7%. Compared to the 3 nearby schools within ~3 miles, this exceeded rate is 10.0 points higher (vs 10.5% average). The gap between "met" and "exceeded" can reveal how much a school's curriculum challenges students beyond proficiency.

The graduation rate is 98.2% — above the state target. 56.5% of students complete A-G requirements for UC/CSU eligibility — a strong college readiness signal. 57.7% of graduates go on to college within a year.

Chronic absenteeism is 14.9%, better than the state average of 34.0%.
