School Overview

Tucked into the foothills of Clayton — one of the East Bay's quieter, more close-knit towns — Mt. Diablo Elementary punches well above its district's overall reputation, consistently landing in the top tier for both English and math. Clayton itself has a small-town feel that's increasingly hard to find in the Bay Area, with trails, a charming downtown, and the kind of neighborhood where kids still walk to school. Families drawn to strong academics without the pressure-cooker atmosphere of some neighboring districts tend to find a really good fit here.
