School Overview

Alpha: Cornerstone Academy Preparatory sits in the heart of East San Jose, a culturally rich neighborhood that's home to one of the Bay Area's most vibrant Latino communities, and the school reflects that spirit while delivering a rigorous K-8 academic program that consistently outperforms most schools in the state. As a charter school, it draws families who are actively seeking out something beyond the default option — parents who want strong academics but also a close-knit school community where kids are known by name. If you're raising a family in the Alum Rock or Story Road corridor, this is the kind of neighborhood gem that makes staying in East San Jose an easy choice.
