Best Public Schools in Zip Code 85310

Zip code 85310 has seven schools serving students from elementary through high school: four elementary schools, one middle school and two high schools; six are in Deer Valley Unified District, while Heritage Academy Pinnacle is part of Heritage Academy Inc. On 2025–26 all-grades results, the schools average 61% in English language arts (ELA) and 55% in math, compared with state averages of 41% and 33%. The clearest area-wide takeaway is that six schools are at least 16 percentage points above the state in both subjects, while Heritage Academy Pinnacle is only 2 points above in each.

Mountain Ridge High School leads in ELA at 73%, 12 points above the next-highest result, 65% at Sandra Day O’Connor High School. In math, Las Brisas Elementary School is highest at 66%, ahead of Mountain Ridge’s 63%; Las Brisas also has the strongest reported fifth-grade science result, 70%, versus 53% at Copper Creek Elementary School and 50% at Desert Sage Elementary School. Heritage Academy Pinnacle is lowest in both all-grades subjects, at 43% in ELA and 35% in math. Desert Sage also has a specific grade-level weakness: its fifth-grade ELA result is 40%, compared with 49% for the district and 38% for the state.

SchoolDigger ranking percentiles show mixed movement rather than a broad upward or downward trend: Mountain Ridge rose from the 90th to the 93rd percentile and O’Connor from the 86th to the 91st, while Copper Creek, Desert Sage and Las Brisas declined; the six schools’ average percentile was about 86% at both endpoints. School size and student-teacher ratios do not offer a simple guide to results: Mountain Ridge has 2,823 students and a 23.9 ratio, while similarly sized O’Connor has 2,658 students and a 24.4 ratio, with lower scores in both subjects. Among the traditional elementary schools, Las Brisas has the lowest ratio at 13.7, but Copper Creek scores higher than Desert Sage despite its higher ratio. Free/reduced-lunch figures are blank, and earlier test scores are not provided, so the data cannot show whether proficiency is changing over time or support comparisons by income.
