What other rankings don't show you

Most rating sites report "55% proficient" for Hidden Valley Elementary and stop there. Here's what that number hides:

24.4% of students exceeded standard while 30.9% merely met it. That exceeded rate is 3.4 points above the state average of 21.0%. That's 5.5 points above the Mt. Diablo Unified district average of 18.8%. Nearby schools (within ~3 miles) average 25.3% exceeded — about the same. The gap between "met" and "exceeded" is the difference between a school that clears the bar and one that raises it.

Proficiency drops by 7.0 percentage points from grade 3 to grade 5 — a signal that the school may not be sustaining early gains.

Chronic absenteeism is 14.4%, better than the state average of 18.7%.
