Summary

Mary B. Lewis Elementary is a K-6 public school serving 548 students in Bloomington, CA, as part of the Colton Joint Unified district, and it faces significant academic and attendance challenges compared to other local schools.

Academically, the school performs below both district and state averages, with particularly low proficiency in math (16.6%) and science (11.8%). It has the highest chronic absenteeism rate (29.7%) among nearby schools in its district, more than double the rate at Ruth Grimes Elementary. The school also spends less per student than most comparison schools in Colton Joint Unified, and there appears to be a relationship within the district where schools with higher spending, like Ruth Grimes Elementary, achieve better results.

Performance varies greatly for different student groups; while results for English Learners have fluctuated year-to-year, the school's effectiveness for students with special education needs is very low. A key finding is that higher achievement is possible in similar communities, as seen at Samuel W. Simpson Elementary in the Rialto Unified district, which earns much higher rankings. Within its own district, Mary B. Lewis consistently ranks below peers like Walter Zimmerman Elementary and Gerald A. Smith Elementary across all major subjects.
