Mary C O'Brien Accommodation District

Mary C O’Brien Accommodation District has two schools: Mary C O’Brien Elementary School, serving kindergarten through grade 6, and Villa Oasis Interscholastic Center for Education (VOICE), serving grades 9–12; there are no middle schools. The clearest academic finding is that the elementary school’s 2025–26 proficiency results are well above Arizona’s in both subjects: 74% in English language arts (ELA) versus 41% statewide, and 72% in math versus 33% statewide.

Mary C O’Brien Elementary stands out at the top of the reportable proficiency results, exceeding the state by 33 percentage points in ELA and 39 points in math; it also tops district results by 17 and 18 points, respectively. VOICE stands out for a different reason: its 2024–25 dropout rate was 19%, compared with 5% statewide, a 14-point gap. That flags a concern for families weighing the high school, but it does not establish its academic standing: VOICE’s 2025–26 proficiency results are suppressed, so the two schools cannot be compared academically from these scores.

Grade-level results at Mary C O’Brien Elementary show an advantage over the state in every grade with reported scores, but grade 4 has smaller gaps than grades 3 and 5. ELA gaps are 41 points in grade 3, 22 in grade 4, 45 in grade 5, and 24 in grade 6; math gaps are 48, 29, and 46 points in grades 3–5. The available figures do not show a test-score trend over time. SchoolDigger’s percentile ranking for the elementary school moved from 99th in 2023–24 to 96th in 2025–26; VOICE’s listed ranking rose from the 11th percentile in 2017–18 to the 22nd in 2021–22. The elementary school has 123 students and a 9.8 student–teacher ratio, compared with 75 students and a 7.1 ratio at VOICE; the schools serve different grade spans, so those figures alone do not indicate which is a better fit.
