Most rating sites report "23% proficient" for Merle S. Casey Elementary and stop there. Here's what that number hides:

7.6% of students exceeded standard while 15.4% merely met it. That exceeded rate is 13.4 points below the state average of 21.0%. That's 5.2 points below the Rialto Unified district average of 12.8%. The 25 nearby schools within ~3 miles average 12.0% exceeded — 4.3 points higher. The gap between "met" and "exceeded" is the difference between a school that clears the bar and one that raises it.
