Summary

Arroyo Elementary is a K-6 public school serving 264 students in the Simi Valley Unified School District, currently ranking in the 34th percentile statewide and showing a recent decline in its academic standing.

The school faces significant challenges, with proficiency rates in English (36%), math (29%), and science (19%) well below both district and state averages. A major concern is chronic absenteeism, affecting over 25% of students, which is strongly correlated with lower academic performance across the district. While Arroyo serves a population with greater economic need than many neighboring schools, it spends more per student ($18,308) than peers like Hollow Hills Elementary ($13,513), which achieves much higher results. Performance also declines in upper grades, and there are notable gaps, with female students scoring significantly lower than male students.

Interesting comparisons within the community show a wide performance range. Schools like Vista Elementary (91st percentile) and Hollow Hills Elementary maintain high rankings with lower chronic absenteeism. Notably, Madera Elementary, located less than a mile away with a similar student demographic, performs significantly better, suggesting factors beyond funding and economics influence outcomes. This indicates Arroyo has potential models for improvement within its own district.
