Original Research by School Decision on Mirus Secondary District
Mirus Secondary District is a single-charter district serving grades seven through twelve in San Bernardino County. The district operates one school, now branded as Altus Schools Mirus, a nonclassroom-based independent-study program that serves a small enrollment. The student body is predominantly Hispanic, with smaller populations of white students and students from other racial and ethnic backgrounds.
The school operates under a personalized, hybrid flex-based independent-study model. It is part of the Altus Schools network, a nonprofit charter school family that shares a common governance structure through a shared CEO Council and Charter SELPA rather than a standalone local board. This consolidation affects how families recognize and interact with the program, as the school now operates under the Altus Schools name and governance framework rather than as a standalone entity.
A significant and ongoing consideration for families relying on this program is a charter authorization dispute that emerged during the 2024-2025 school year. The school was originally established within Desert Sands Unified's boundaries but was authorized by Hesperia Unified, which is located outside that service area. California's geographic restrictions on nonclassroom-based charters created questions about the legality of this arrangement. A petition tied to the school's charter renewal was submitted to Desert Sands Unified in the summer of 2024, withdrawn after staff recommended denial later that year, and resubmitted with a revised budget. This uncertainty over the charter's legal footing is a material concern for families considering enrollment, as the program's continued operation and location depend on resolution of these authorization questions. A parent may want to contact the district directly to understand the current status and timeline of this dispute.
State testing data and four-year graduation rates were not available for the district, likely reflecting the nonclassroom-based nature of the program and the specialized reporting requirements that may apply to independent-study schools.
Among San Bernardino County's districts, chronic absenteeism is notably high, placing the district in the bottom quartile. Per-pupil current spending falls in the lower-middle range among the county's districts. These figures warrant direct conversation with the school about how it supports attendance and whether the independent-study format affects these metrics differently than traditional schools.
The district serves families seeking flexible, personalized learning outside a traditional classroom setting. For those considering enrollment, understanding the current charter status and the school's position within the Altus Schools network will be essential steps in evaluating whether this program is the right fit.
