What other rankings don't show you

Most rating sites report "15% proficient" for Mariano Castro Elementary and stop there. Here's what that number hides:

6.9% of students exceeded standard while 8.3% merely met it. That exceeded rate is 14.1 points below the state average of 21.0%. That's 34.5 points below the Mountain View Whisman district average of 41.4%. The 21 nearby schools within ~3 miles average 57.8% exceeded — 50.9 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 14.5 percentage points from grade 3 to grade 5 — a signal that the school may not be sustaining early gains.

Chronic absenteeism is 23.9%, above the state average of 18.7%.
