School Overview

Tucked into the Willow Glen-adjacent neighborhoods of southwest San Jose, Oster Elementary is the kind of school that draws families to this corner of the city on purpose. With math and science scores in the 97th percentile statewide, it's a natural fit for academically driven families who want rigorous fundamentals without the chaos of a bigger urban district. The surrounding area has a quiet, established feel — tree-lined streets, good parks, and easy access to both downtown Willow Glen's cafes and the broader South Bay — making it a genuinely livable place to put down roots.
