What other rankings don't show you

Most rating sites report "28% proficient" for Rio Vista Elementary and stop there. Here's what that number hides:

11.8% of students exceeded standard while 16.0% merely met it. That exceeded rate is 9.1 points below the state average of 21.0%. That's 25.9 points below the Placentia-Yorba Linda Unified district average of 37.7%. The 20 nearby schools within ~3 miles average 17.3% 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 18.0 percentage points from grade 3 to grade 5 — a signal that the school may not be sustaining early gains.

Chronic absenteeism is 27.7%, above the state average of 18.7%.
