Summary

Willow Elementary is a K-6 public school serving 388 students in the Charter Oak Unified School District, consistently ranking as a 4-star school that outperforms its district and state averages in English and Math.

The school is a strong performer within its own district, particularly in mathematics and in effectively supporting students from economically disadvantaged backgrounds. Along with Washington Elementary, it forms a higher-performing tier compared to other district schools like Cedargrove, Badillo, and Glen Oak. However, when compared to high-achieving schools in neighboring districts like Arma J. Shull Elementary in Bonita Unified, Willow's results, while solid, appear more modest despite having higher spending per student.

Key challenges for Willow include a high rate of chronic student absenteeism and a noticeable drop in test scores in the upper grades, despite exceptional results in the early grades. Its main strengths are maintaining good academic performance despite a rapid increase in the number of students qualifying for free lunch, and its demonstrated success in teaching math and supporting specific student subgroups.
