What other rankings don't show you

Most rating sites report "75% proficient" for Sonoma Mountain Elementary and stop there. Here's what that number hides:

47.1% of students exceeded standard while 28.3% merely met it. That exceeded rate is 26.1 points above the state average of 21.0%. That's 24.6 points above the Old Adobe Union district average of 22.5%. Compared to the 13 nearby schools within ~3 miles, this exceeded rate is 29.7 points higher (vs 17.4% 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 14.5 percentage points from grade 3 to grade 5 — a signal that the school may not be sustaining early gains.

Chronic absenteeism is 5.1%, better than the state average of 18.7%.
