Summary

Mariana Academy serves 781 students in kindergarten through eighth grade in Apple Valley, in the high-desert area of San Bernardino County, and is part of Apple Valley Unified. In 2025–2026, its all-grades proficiency rates were 22% in English language arts (ELA), 14% in math, and 21% in science. The most important takeaway is that results remain substantially below California’s rates in all three subjects, despite recent improvement.

Science is the school’s relative bright spot: its rate was 15 percentage points below the state and just 1 point below the district, compared with gaps of 28 and 10 points in ELA and 24 and 4 points in math. Among nine nearby schools with results, Mariana’s science was fourth-lowest; its ELA and math were each third-lowest. Nearby averages were 32% in ELA, 22% in math, and 26% in science, all above Mariana’s results. ELA is the weakest comparison with the district, while science comes closest to both the district and state.

Scores have risen over the four reported years, but not steadily: ELA and math each gained about 5 percentage points, and science gained 11; their gaps with the state narrowed by about 3, 1, and 5 points, respectively. Chronic absenteeism also improved, from 55% in 2021–2022 to 30% in 2025–2026, though the latest rate remains 12 points above the state. SchoolDigger rates Mariana at the 12th statewide percentile and 1 star, up from the 6th percentile and 0 stars the prior year. Its 2024–2025 free/reduced lunch eligible rate was 84%, and its student-teacher ratio was 25, tied for the second-highest among nearby schools with reported ratios; only Endeavour School of Exploration was higher, at 25.6. SchoolDigger’s subgroup rankings show stronger relative standing for Homeless Students (44th percentile in 2025–2026 versus 12th overall) and a weaker longer-term trajectory for English Language Learner Students, whose ranking fell from the 55th percentile in 2018–2019 to the 22nd in 2023–2024, after reaching the 10th in 2022–2023.
