Most rating sites report "10% proficient" for Potrero Elementary and stop there. Here's what that number hides:
2.1% of students exceeded standard while 7.8% merely met it. That exceeded rate is 18.8 points below the state average of 21.0%. That's 5.6 points below the Mountain Empire Unified district average of 7.8%. The gap between "met" and "exceeded" is the difference between a school that clears the bar and one that raises it.
Proficiency drops by 0.9 percentage points from grade 3 to grade 5 — a signal that the school may not be sustaining early gains.
Chronic absenteeism is 41.6%, above the state average of 18.7%.
