Old Adobe Union


Summary:

The Old Adobe Union School District in Petaluma serves about 1,734 students across five elementary schools (grades K-6), ranking in the 60th percentile among California districts, with significant variation in performance between its schools.

Sonoma Mountain Elementary stands out as the district's top performer, ranking in the 92nd percentile statewide with exceptionally high scores in English, math, and science, coupled with very low chronic absenteeism. In contrast, Miwok Valley Elementary Charter faces considerable challenges, ranking in the 10th percentile with proficiency rates well below district averages, particularly in science, despite having the highest per-student spending. The other three schools—La Tercera Elementary, Old Adobe Elementary Charter, and Loma Vista Immersion Academy—perform near or slightly above state averages, with La Tercera showing notable recent improvement.

Key takeaways for parents include a strong correlation between lower economic disadvantage and higher academic outcomes, as seen at Sonoma Mountain, and a clear link between lower chronic absenteeism and better performance. The data shows charter schools in the district have widely different results, indicating school-specific factors are crucial. While the district overall performs well, these internal disparities highlight both models of excellence and areas where families may want to seek specific information about support and programs.
