Summary:
ZIP code 85259 has one listed high school, Desert Mountain High School, serving grades 9–12 with 1,905 students in the Scottsdale Unified District. With no other high schools in the list, families can compare the school with district and state figures, but not with local peers. Its clearest strength is that proficiency rates are above state rates in every subject-and-grade comparison provided.
Desert Mountain is both the top and bottom school in this ZIP code by default, so those labels do not indicate a meaningful local ranking. In 2025–26, all-grade ELA proficiency was 72%, 31 percentage points above the state and 11 above the district; mathematics was 62%, 29 points above the state and 6 above the district. Grade 11 showed a similar pattern: ELA was 72% and mathematics 62%, respectively 34 and 31 points above state rates. The 2024–25 graduation rate was 97%, compared with 80% statewide and 94% in the district—about 17 points above the state and 3 above the district.
SchoolDigger’s statewide ranking improved in the latest reported year, though rank history is not a record of changing test scores: the school went from 40 of 270 (85th percentile) in 2023–24 to 52 of 271 (81st percentile) in 2024–25, then to 21 of 256 (92nd percentile) in 2025–26; SchoolDigger gives it 5 stars. Grade 11 science is a more modest, positive state comparison: 27% proficiency in 2024–25, 8 points above the state and 5 above the district. The student–teacher ratio is 20.5, and no free/reduced-lunch figure is provided. Because only one school is listed, the data cannot show local school-to-school differences.
