Summary

Charlotte N. Werner Elementary is a public K-5 school serving 739 students in the Rialto Unified School District, but it faces significant academic challenges, ranking in the bottom 10% of all California elementary schools.

The school's academic performance is notably low, with only about a quarter of students proficient in English and less than 15% proficient in math, which are the lowest rates among nearby schools. A major concern is chronic absenteeism, with nearly one in three students missing too much school—a rate much higher than at neighboring schools like Samuel W. Simpson Elementary (14.5%) or Helen L. Dollahan Elementary (14.2%). Interestingly, Werner Elementary spends more money per student than these higher-performing schools, suggesting that resources alone are not solving its core issues.

Despite serving a community with high economic need, the comparison with Samuel W. Simpson Elementary shows that strong results are possible in similar settings, as that school ranks in the top quarter of the state. For improvement, Werner Elementary likely needs to focus intensely on improving student attendance and ensuring its substantial funding is directed toward the most effective academic and support programs for its students.
