The top reported proficiency rate is 34% in English language arts. The lowest is 14% in Science.
Original Research by School Decision on Mirus Secondary
Mirus Secondary is a small charter school operating from Hesperia as a personalized, independent-study hybrid program now branded under the Altus Schools network. It enrolls students in grades from early secondary through high school, with enrollment concentrated in the ninth and tenth grades. The school serves a population that is predominantly Hispanic and economically under-resourced, with a substantial share of students qualifying for free or reduced-price lunch. The charter is newly rebranded as part of a broader Altus Schools consolidation, which means governance runs through a shared CEO Council and Charter SELPA structure rather than a standalone local board.
The academic results are notably weak across all tested subjects. Proficiency in English language arts sits in the mid-range for the school overall, with seventh and eighth graders showing slightly different performance levels. Mathematics proficiency is very low in both grades tested. Science proficiency is similarly low. On the statewide proficiency index that pools performance across subjects and grades, the school sits in the bottom quartile among the county's districts that report comparable data.
The school operates as a nonclassroom-based program with a flexible independent-study model, which appeals to families seeking alternatives to traditional classroom structures. This model may serve students with scheduling conflicts, medical needs, or learning preferences that fit self-paced coursework better than a conventional classroom. However, the program's legal footing is uncertain. The school was established within Desert Sands Unified boundaries but is authorized by Hesperia Unified, creating a geographic mismatch that triggered a charter authorization and validity dispute in 2024-2025. A petition tied to the school's renewal was submitted, then withdrawn, then resubmitted after staff review. For families considering enrollment, this uncertainty over whether and under what terms the charter will continue to operate is a material risk that a parent may want to look into directly with the school and its authorizer.
The school's enrollment is small, with the heaviest concentration in ninth and tenth grades. This means the school has limited peer diversity in terms of size and composition, and few students are present in the seventh and eighth grade cohorts or in the upper grades. The independence-study model may suit some families' needs, but it typically offers less peer interaction, structured extracurricular activity, and day-to-day social engagement than a conventional school. A parent interested in this setting should understand what in-person or synchronous support and peer connection the program actually provides.
State testing data for seventh and eighth grade students is available, showing proficiency rates in both English language arts and mathematics. Eighth graders were assessed in science as well. No multi-year trend data is available yet, so it is not possible to assess whether performance is improving or declining. Graduation rate data was not available, likely because the school's recent vintage or enrollment patterns mean that cohorts have not yet completed high school and been counted in graduation statistics. A parent seeking to understand outcomes for high school completers may want to ask the school directly about completion and transcription data for recent cohorts.
Housing in the Hesperia area is modestly valued relative to state benchmarks, with median home values below the California statewide benchmark and rents growing slightly year over year. The broader San Bernardino County economic context shows moderate unemployment and stable household income, with mortgage rates in the mid-to-high range, reflecting the cost environment families in the region navigate.
