Summary

Brewer Island Elementary is a highly-regarded K-5 public school serving 306 students in the family-friendly, planned community of Foster City, part of the San Mateo-Foster City School District.

This school is a consistent top performer, ranking in the 91st percentile of all California elementary schools and earning 5-star ratings for most of the past decade. Students here significantly outperform both district and state averages, especially in mathematics where 75% are proficient. The school also maintains a strong culture of attendance, with chronic absenteeism rates consistently lower than the district and state. Notably, Brewer Island has a proven record of effectively supporting economically disadvantaged students and English learners, ranking in the 97th percentile statewide for its low-income student subgroup.

While Sandpiper Elementary and Redwood Shores Elementary in the neighboring Belmont-Redwood Shores Elementary district achieve similar excellence, Brewer Island stands out within its own district. It is a top-tier school alongside Foster City Elementary, while other nearby schools in the same district, like LEAD Elementary and Fiesta Gardens International Elementary, struggle significantly. This contrast highlights Brewer Island's effective teaching practices and resource management, achieving outstanding results even as its student demographics shift.
