Mojave River Academy - Silver Mountain scores 33 of 100 on SchoolScope's Scope Score — the 25th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

Most rating sites would stop at “9% proficient” and call it done. Mojave River Academy - Silver Mountain deserves a closer read. The school sits in Barstow, where four in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

The headline number: 9.0% chronic absenteeism — versus 17.9% statewide. Attendance is the quietest strong signal a school can post.

As a charter, Mojave River Academy - Silver Mountain enrolls by application, not address — the score reads the same, the enrollment path doesn't.
