Summary

Charleston Elementary is a public K-6 school serving 374 students in the Los Banos Unified school district, standing out as a relatively strong performer within a district that faces significant academic challenges across California.

Academically, Charleston consistently outperforms the district average in all subjects, with particularly notable leads in English and Math compared to nearby schools like Henry Miller Elementary and R. M. Miano Elementary. Its most exceptional strength is student attendance; the school's chronic absenteeism rate of 10.3% is less than half the district average and represents a dramatic, successful improvement from just a few years ago. This focus on attendance appears to be a key driver of its success, especially when compared to other schools with similar student demographics.

While the school's statewide ranking has fluctuated, it currently performs around the middle compared to all California elementary schools. It spends more per student than some higher-performing peers like Grasslands Elementary, which raises questions about resource efficiency. Overall, Charleston Elementary demonstrates that a strong focus on foundational supports like attendance can help a school achieve solid results for its students even within a challenging broader district context.
