OCS - South

Tucked into the foothills community of Altadena, OCS South is a K-8 charter school that draws families looking for something a little different from the traditional public school experience — and consistently delivers strong academic results across English, math, and science. Altadena has a distinct, unincorporated character that sets it apart from the more polished parts of the San Gabriel Valley: tree-lined streets, a tight-knit creative community, and easy access to hiking trails that spill down from the San Gabriel Mountains. Families who value a school that punches above its weight academically while still feeling rooted in a genuinely neighborhood-oriented community tend to find OCS South a great fit.
