Summary

Adele Harrison Middle is a public school serving 334 students in grades 6-8 within the Sonoma Valley Unified district, which faces broader statewide challenges.

The school is navigating a period of change, with its statewide ranking having declined in recent years to the 41st percentile. This trend is occurring even as it maintains a significant strength in student attendance, with a chronic absenteeism rate of 13.8% that is better than both the district average and most nearby schools like Silverado Middle (31.8%) and Petaluma Junior High (17.4%). Academically, the school shows a notable performance gap between male and female students and has particular challenges in mathematics proficiency, which lags behind the state average. However, it performs science notably better than the district average.

When compared to other schools, Adele Harrison operates with considerably lower per-student spending than many peers, such as Altimira Middle in the same district, yet achieves better academic results. The contrast with exceptionally high-performing schools like Petaluma Accelerated Charter suggests instructional models and culture are key factors. The school's support for specific student subgroups has shown inconsistency in recent years, even as its efficient use of limited resources remains a point of distinction in the region.
