Summary:
ZIP code 85215 has one listed school, K-8 STEM Academy at Red Mountain Ranch, serving prekindergarten through grade 8 and enrolling 473 students. Its 2025–26 all-grades AASA proficiency was higher than Arizona’s in both reported subjects: ELA was 53% versus 41%, and math was 46% versus 33%.
The school also exceeded Mesa Unified District averages, by 14 percentage points in ELA (53% versus 39%) and 15 points in math (46% versus 31%). Grade-level results show strengths as well as variation: every reported grade 3–7 result was above its state counterpart, but ELA ranged from 42% in grade 5 to 63% in grade 7, while math ranged from 36% in grade 7 to 57% in grade 4. Grade 5 was closer to state results—4 points higher in ELA and 6 points higher in math—while grade 7 ELA was 20 points higher. The 2024–25 fifth-grade science result was 37%, just 3 points above the state’s 34%.
SchoolDigger’s overall percentile ranking edged down over the three reported years, from 73 in 2023–24 to 72 in 2024–25 and 68 in 2025–26; its reported rank shifted from 247 of 912 to 288 of 900. The student-teacher ratio was 15.7 in 2024–25. Because this is the only listed school, there is no comparison with other ZIP-code schools; ELA and math results cover one year, the free/reduced-lunch figure is not provided, and the ranking history is not a test-score trend.
