Summary

Quail Summit Elementary is a top-performing K-5 public school with about 696 students in Diamond Bar, part of the high-achieving Walnut Valley Unified district, consistently ranking in the top 5% of all California elementary schools.

The school excels academically, with over 81% of students proficient in math and 69% in science, significantly outpacing state averages and performing strongly even within its competitive district; it is comparable to Walnut Elementary and slightly outperforms Evergreen Elementary, though Maple Hill Elementary holds the top spot. Quail Summit's most distinctive strength is its exceptional effectiveness in supporting historically underserved student groups, such as English Language Learners and students from low socioeconomic backgrounds, ranking in the 99th percentile statewide for helping these students succeed.

Notably, the school achieves these excellent results with efficient use of resources and maintains very low chronic absenteeism at 6.4%. An interesting finding is that performance isn't strictly tied to district or spending, as seen with Pantera Elementary in the Pomona Unified district, which performs similarly despite being in a lower-ranked district, highlighting that individual school practices are crucial.
