Most rating sites report "24% proficient" for Mary B. Lewis Elementary and stop there. Here's what that number hides:

5.9% of students exceeded standard while 17.9% merely met it. That exceeded rate is 15.1 points below the state average of 21.0%. That's 4.2 points below the Colton Joint Unified district average of 10.1%. The 22 nearby schools within ~3 miles average 11.8% exceeded — 5.9 points higher. The gap between "met" and "exceeded" is the difference between a school that clears the bar and one that raises it.

Chronic absenteeism is 29.7%, above the state average of 18.7%.
