Summary

Gladstone Elementary is a K-5 public school serving 518 students in San Dimas, operating as a solidly performing 4-star school within the highly-regarded Bonita Unified School District.

Academically, Gladstone consistently outperforms state averages, with particular strength in mathematics where it even exceeds the district average; however, its science scores are an area for improvement. The school demonstrates exceptional effectiveness in supporting specific student groups, ranking in the top percentiles statewide for Hispanic students and those from low socioeconomic backgrounds. Parents should note the school's chronic absenteeism rate, while improved from pandemic highs, remains higher than some neighboring schools and is a recognized focus area.

Interesting comparisons within the same district reveal that school-level factors matter greatly. For instance, Arma J. Shull Elementary, located less than a mile away, achieves higher proficiency and lower absenteeism. Meanwhile, Gladstone's math performance is a standout compared to other Bonita Unified schools like Fred Ekstrand Elementary and Allen Avenue Elementary. Overall, being part of the strong Bonita Unified district is an advantage, as its schools generally outperform those in neighboring districts like Charter Oak Unified.
