Summary:
This analysis examines four elementary schools (grades K-5) in the San Dimas, CA area (zip code 91773), all part of the high-performing Bonita Unified school district, which ranks in the 87th percentile statewide.
Among these schools, Arma J. Shull Elementary stands out as a top-tier institution, consistently ranking in the top 5% of California elementary schools with exceptional test scores and a 5-star rating. The other three schools—Gladstone Elementary, Fred Ekstrand Elementary, and Allen Avenue Elementary—perform well above the state average but show notable variation. Gladstone maintains a solid 4-star rating, while Ekstrand and Allen Avenue have lower proficiency rates in core subjects.
Key factors differentiating these schools include chronic absenteeism, which is remarkably low at Arma J. Shull (6.3%) but higher at others, and per-student spending, which is similar across all four. Interestingly, Arma J. Shull achieves its top results despite having the largest class sizes. The data suggests that while all schools in this area are strong, parents should note specific strengths, such as Allen Avenue's relatively high science scores, and consider the strong correlation between regular attendance and academic success observed across the district.
