Peoria Unified School District

Peoria Unified School District includes 43 schools—33 elementary, eight high schools and two alternative schools—serving students from elementary through high school grades in the Peoria area. Across 41 schools with all-grade scores, the unweighted averages are 42% in English language arts (ELA) and 35% in math, compared with state averages of 41% and 33%. The most important finding is how widely results vary from one school to another: all-grade scores span 24% to 80% in ELA and 12% to 80% in math.

Peoria Traditional School is the clearest standout, with 80% proficiency in both subjects—39 percentage points above the state in ELA and 47 points above it in math. SchoolDigger ranks it 32nd of 900 Arizona elementary schools and awards it five stars. Among conventional high schools, Sunrise Mountain High School leads in all-grade ELA at 53%, while Liberty High School leads in math at 45%. At the lower end, Sun Valley Elementary School reports 24% ELA and 16% math; Ira A. Murphy has the lowest reported math result, 12%. SchoolDigger places Sun Valley and Country Meadows Elementary School in the 9th and 10th statewide percentiles, respectively.

SchoolDigger’s ranking history is broadly flat for elementary schools but weaker for conventional high schools: among schools with results in both years, elementary rankings changed by an average of about 1 percentile point from 2023–24 to 2025–26, while high-school rankings fell by an average of 13 points. Individual schools moved in different directions: Copperwood School rose 19 percentile points, while Heritage School fell 16. Grade-level results can also differ sharply from a school’s overall picture: Centennial High School reports 95% eighth-grade ELA, and Sunrise Mountain reports 97% eighth-grade math. A low student-teacher ratio alone does not signal stronger results: Coyote Hills Elementary School has a ratio of 11.7 and 52% ELA, while Peoria Elementary School has a similar ratio of 12.8 and results of 33% ELA and 24% math. SchoolDigger rankings show relative standing rather than changes in test scores, and the supplied data include no usable free/reduced-lunch rates.
