Summary

Altimira Middle is a public school serving about 324 students in grades 6-8 within the Sonoma Valley Unified district, but it faces significant academic challenges, ranking in the bottom quarter of all California middle schools.

The school's test scores in English, math, and especially science are well below both state and district averages, and it has shown a multi-year decline in its statewide ranking. While the school spends more per student than the higher-performing Adele Harrison Middle in the same district, it achieves notably weaker results. Performance gaps exist for different student groups, and science proficiency is a particular area of concern, with only about 6% of students testing as proficient.

Comparisons to nearby schools suggest these challenges can be addressed; for instance, Unidos Middle serves a student population with greater economic need yet achieves much stronger academic outcomes. The school's data shows some strengths, like a lower chronic absenteeism rate than the state average and a favorable student-teacher ratio, but reversing its academic trajectory will require focused attention on curriculum and resource effectiveness.
