What other rankings don't show you

Most rating sites report "30% proficient" for Muir (John) Elementary and stop there. Here's what that number hides:

9.1% of students exceeded standard while 20.9% merely met it. That exceeded rate is 11.9 points below the state average of 21.0%. That's 3.1 points above the Antioch Unified district average of 6.0%. Compared to the 12 nearby schools within ~3 miles, this exceeded rate is 3.3 points higher (vs 5.8% average). The gap between "met" and "exceeded" is the difference between a school that clears the bar and one that raises it.

Proficiency drops by 4.3 percentage points from grade 3 to grade 5 — a signal that the school may not be sustaining early gains.

Chronic absenteeism is 31.7%, above the state average of 18.7%.
