School Overview

Mojave River Academy's Marble City campus serves families across the high desert communities around Phelan, offering a K-12 charter experience that draws students from a wide stretch of San Bernardino County's more rural corners. As an independent study-based charter, it tends to appeal to families who want flexibility in how and where their kids learn — a common priority out in the Inland Empire's sprawling desert landscape, where commutes are long and community looks a little different than in denser suburbs. The academics here are still developing, and families who prioritize strong English and math scores may want to weigh their options, but for those who value structure within a non-traditional model and live in an area where choices are limited, it fills a real need.
