SchoolDigger Rank ?

of 5,857 California Elementary Schools

Better than 24% of California elementary schools

Summary

Arroyo Elementary is a K-8 public school serving 493 students in the Ontario-Montclair School District, but its academic performance ranks in the bottom quarter of all California elementary schools.

When compared to other schools in the same district, Arroyo's academic results are significantly lower; for example, in English and Math, student proficiency rates are roughly half those of higher-performing schools like Edison Elementary. This gap exists even when comparing to schools with similar student populations, such as Corona Elementary, which achieves better results. A particularly concerning area is the school's services for students in special education, which rank in the bottom 10% statewide. While chronic student absences have improved recently, they remain higher than the district average.

Performance varies widely by grade, with middle school English scores nearing state averages but science and 6th-grade math scores being critically low. The school spends more per student than some top-performing peers, yet these resources have not translated into better academic outcomes. Parents may want to investigate how the school plans to address these specific challenges, especially in special education and consistent teaching quality across all grades.
