What other rankings don't show you

Most rating sites report "47% proficient" for Sumner Elementary and stop there. Here's what that number hides:

20.3% of students exceeded standard while 26.7% merely met it. That exceeded rate is near the state average of 21.0%. That's 8.4 points below the Claremont Unified district average of 28.7%. The 16 nearby schools within ~3 miles average 25.8% exceeded — 5.5 points higher. The gap between "met" and "exceeded" is the difference between a school that clears the bar and one that raises it.

Proficiency drops by 5.4 percentage points from grade 3 to grade 5 — a signal that the school may not be sustaining early gains.

Chronic absenteeism is 16.2%, better than the state average of 18.7%.
