School Overview

Tucked away in the high desert of Lassen County, Mt. Lassen Charter serves the small community of Herlong — a remote Sierra Army Depot town where the student body is tight-knit by necessity and the school truly is the center of community life. Academics here are a work in progress, with test scores sitting in the lower ranges statewide, so families who prioritize strong fundamentals in English and math may want to weigh their options carefully. That said, for military and working families rooted in Herlong with few nearby alternatives, this K-12 charter offers the continuity of keeping kids in one place from kindergarten through graduation in a setting where teachers and staff tend to know every student by name.
