Summary:

The Rialto Unified school district serves nearly 20,000 students across 29 schools in Southern California, ranging from elementary through high school, within a community where the vast majority of students qualify for free or reduced-price lunch.

When comparing schools, standout performers include Samuel W. Simpson Elementary, which ranks in the top quarter of all state schools and excels in English and math, and Wilmer Amina Carter High, the district's highest-ranked high school with strong graduation rates and science scores. In contrast, schools like Charlotte N. Werner Elementary and Warren F. Frisbie Middle face significant academic challenges and rank much lower statewide.

Key district insights show high schools generally perform better than elementary and middle schools, particularly in English, but math proficiency is a major concern across all grades. Chronic absenteeism is a strong indicator of performance, with schools like W.J.C. Trapp Elementary having excellent attendance and high rankings, while others struggle. Interestingly, higher per-student spending does not automatically lead to better results, suggesting other factors are critical for student success.
