Summary

Merle S. Casey Elementary is a K-5 public school serving 563 students in the Rialto Unified School District, consistently ranking in the bottom quartile of California elementary schools despite recent increases in per-student funding.

The school faces significant academic challenges, with proficiency rates in English, math, and science that are well below both the district and state averages. A major concern is the school's high chronic absenteeism rate of 31.6%, which is the highest among nearby schools like J.P. Kelley Elementary (19.2%) and Georgia F. Morris Elementary (18.5%). Performance data also shows a notable gap between male and female students, with boys ranking significantly lower statewide.

While all schools in the area serve high-needs communities, Merle S. Casey Elementary has the highest percentage of students qualifying for free or reduced-price lunch. Interestingly, despite having higher per-student spending than peers such as A. H. Morgan Elementary, it yields the lowest academic outcomes, suggesting a need to examine how resources are used. The school's performance has been volatile year-to-year, particularly for special education and homeless student subgroups.
