Summary:
ZIP code 92308 has eight schools in Apple Valley Unified: six elementary schools, one high school and one alternative school, serving grades from kindergarten through grade 12. In 2025–26, their average proficiency was 30% in English language arts (ELA), 18% in math and 24% in science, compared with state averages of 49%, 38% and 36%. The clearest takeaway is the wide gap between schools: results range from near the state level or above it in some subjects to very low proficiency at the bottom.
Apple Valley High led in all-grades ELA at 49%, essentially matching the 49% state result. Among the K–6/K–8 schools, Rio Vista School of Applied Learning had the strongest ELA and math results, at 39% and 27%. Apple Valley Virtual Academy led in science at 46%, 10 points above the state. At the other end, High Desert Premier Academy had the lowest results in all three subjects: 10% in ELA, 1% in math and 5% in science. Its 73% chronic absenteeism was also the highest reported.
Area averages rose from 2024–25 to 2025–26 in math, by 2 percentage points, and science, by 6 points; ELA was nearly unchanged, so its gap with the state did not close. School-level changes varied: the Virtual Academy’s science result rose 26 points while its ELA fell 8, and Mariana Academy science rose 14 points. SchoolDigger places Sitting Bull Academy, Vanguard Preparatory and Sandia Academy below the 10th statewide percentile; the Virtual Academy is at the 9th percentile. Context differs too: 2024–25 free/reduced lunch eligible figures ranged from 63% at Rio Vista to 88% at Sandia, while their student–teacher ratios were 25.0 and 21.6, respectively—so these measures do not line up simply with test results.
