School Overview

Tucked into the hills of San Diego County, Mountain Oaks is a K-8 charter school that draws families who want something a little different from the traditional public school experience — and delivers strong results across the board, with English and math scores consistently landing in the top 10% statewide. The school has a tight-knit feel that's hard to find at larger campuses, making it especially appealing to families who value smaller communities and engaged parent involvement. Encinitas itself is one of those rare places where surf culture, outdoor living, and an emphasis on wellness all coexist, and Mountain Oaks fits right into that ethos.
