School Overview

Lafayette is one of those Lamorinda towns where the trails, top-notch schools, and tight-knit community all feed into each other, and Acalanes High sits right at the heart of that culture. Academics here are genuinely rigorous — strong across English, math, and science — making it a great fit for families who want a public school experience that keeps up with the best private options in the Bay Area. If you're drawn to a walkable, suburban feel with easy BART access to the city but a slower, more community-rooted pace at home, the Acalanes district is a big part of what makes Lafayette such a sought-after place to put down roots.
