Summary

Stanley G. Oswalt Academy is a high-performing K-8 public school serving 879 students in the Rowland Unified School District in Walnut, CA, that consistently ranks in the top quarter of all California schools.

The school stands out dramatically within its own district, ranking in the 82nd percentile statewide while neighboring Rowland Unified schools like Rorimer Elementary (24th percentile) and Yorbita Elementary (13th percentile) perform significantly lower. Oswalt achieves this with efficient use of resources, spending less per student than some district peers, and maintains an exceptionally low chronic absenteeism rate of 7.0%, less than half the district average.

Perhaps most impressively, the school demonstrates remarkable effectiveness with vulnerable student groups, with its homeless students ranking in the 96th percentile statewide and its low-income students consistently in the 89th-91st percentile. While it doesn't quite match the peak performance of some schools in the neighboring Walnut Valley Unified district, such as Leonard G. Westhoff Elementary, Oswalt Academy proves that strong academic outcomes are achievable across diverse student populations.
