Best Public Schools in Zip Code 85225

Schools in ZIP code 85225 include 27 schools, from elementary through high school, along with alternative programs, and reported achievement averages are close to statewide results. Among schools reporting both subjects, average proficiency was 43% in English language arts (ELA) and 35% in math, compared with 41% and 33% statewide. The central finding is that those near-state averages conceal very large differences from one school to another.

Knox Gifted Academy led reported all-grades ELA at 92%, while BASIS Chandler Primary – North Campus led math at 94%; each was more than 50 points above its subject’s state result. SchoolDigger ranked Knox 2nd of 900 Arizona elementary schools and BASIS 3rd, with five stars for each. At the other end, AZ Compass Prep School reported 14% ELA, 27 points below state, and Primavera – Online reported 8% math, 25 points below. Galveston Elementary was also low, at 19% ELA and 17% math; SchoolDigger ranked it 872nd of 900, in the 3rd percentile, with zero stars.

SchoolDigger’s ranking history shows no common direction: among 13 schools with figures for both 2023–24 and 2025–26, the average change was essentially zero percentile points, with Frye Elementary gaining 14 points and Willis Junior High losing 12. School size and staffing ratios do not neatly predict results: Liberty Campus and Hartford Sylvia Encinas Elementary serve PK–6 and enroll similar numbers, but Liberty was 33 points higher in both ELA and math, despite Hartford’s lower student–teacher ratio (15 versus 18). Completion figures also distinguish high schools: Primavera’s graduation rate was 33%, compared with 80% statewide, while its dropout rate was 16% versus 5% statewide. Some results are suppressed, and differing grade spans limit direct comparisons.
