Elementary Schools in Rialto Unified

Summary:

This analysis covers 19 elementary schools (grades K-5) within the Rialto Unified School District in California, a district ranking in the 34th percentile statewide where academic performance and resources vary significantly from school to school.

There are notable standout schools, with Samuel W. Simpson Elementary and W.J.C. Trapp Elementary leading in test scores and having the lowest chronic absenteeism rates. In contrast, Charlotte N. Werner Elementary and Merle S. Casey Elementary face the greatest challenges, with the lowest proficiency rates and highest absenteeism. Nancy R. Kordyak Elementary is another consistent performer with strong math scores.

Key takeaways for parents include the strong link between attendance and performance, with top schools having much lower chronic absenteeism. Mathematics is a particular challenge across the district, with most schools scoring below the state average. Interestingly, higher per-student spending does not automatically mean better results, as some lower-performing schools have higher funding. The data shows that even within the same district, school-level factors create wide disparities in student outcomes.
