Summary:
Wittmann has three schools in the Nadaburg Unified School District, serving students from prekindergarten through grade 12: Nadaburg Elementary School (PK–8), Mountainside High School (9–12), and Nadaburg Online Virtual Academy (7–12). The clearest difference in the available results is that Mountainside’s overall English language arts proficiency is above the state figure, while Nadaburg Elementary’s is well below it.
Mountainside High School stands out most positively: 44% of students were proficient in overall ELA, 3 percentage points above Arizona’s 41%; in grade 11, the school was 6 points above the state. Its overall math result was closer to the state figure, at 31% versus 33%. Nadaburg Elementary School was below the state in every reported overall comparison: ELA was 25% versus 41%, and math was 17% versus 33%—16 points below in each subject. Its grade-level results vary: grade 6 ELA was 37% versus 41% statewide, while grade 4 ELA was 29% versus 47%. The online academy has 8 students and no reported test results, so its performance cannot be compared.
Mountainside’s SchoolDigger percentile rose from 33 in 2023–24 to 54 in 2025–26, while Nadaburg Elementary’s slipped from 25 to 22; both currently share a SchoolDigger rating of 2 stars and a reported rank of 180 out of 267. Mountainside also had an 85% graduation rate, compared with 80% statewide. Student-teacher ratios were 11 at Mountainside and 8.3 at Nadaburg Elementary; no ratio was reported for the online academy. SchoolDigger rankings are not test-score trends, and the schools’ different grade spans—and the academy’s lack of test results—limit direct comparisons.
