School Overview

Riverside Preparatory is a K-12 charter school serving the small high desert community of Oro Grande, tucked along the old Route 66 corridor between Victorville and Barstow. Families out here tend to value the close-knit feel of a smaller school where kids aren't lost in the shuffle, and the all-grades-under-one-roof setup means siblings can stay together and staff get to know students over many years. If you're drawn to the Mojave's wide-open spaces and a quieter pace of life away from the city, and you're looking for a school that offers that continuity from kindergarten through graduation, Riverside Prep is worth a closer look — though families with strong academic priorities may also want to explore what additional enrichment options are available in the surrounding High Desert area.
