Summary:
ZIP code 85255 has five schools spanning elementary, middle and high school grades: three elementary schools, one middle school and one high school. Among the four schools with reported 2025–26 results, every school is above Arizona’s average in both subjects: their average is 66% in English language arts (ELA), 25 percentage points above the state, and 60% in math, 27 points above. The biggest difference between schools is in math: results span 20 points, compared with 7 points in ELA, making school-to-school variation in math the most important distinction in this area.
Desert Canyon Elementary leads the reporting schools overall, with 70% proficient in ELA and 68% in math. Copper Ridge School has the lowest All Grades math result, 48%—16 points below the average of the other three schools—although its grade 4 results are strong at 78% in both subjects. In a same-grade comparison for grades 6–8, Desert Canyon Middle School averages 59% in math, compared with 40% at Copper Ridge, a 19-point gap; ELA tilts the other way, with Copper Ridge averaging 68% and Desert Canyon Middle 65%. Grayhawk Elementary School is also strong, with 65% in All Grades math and ELA.
SchoolDigger’s statewide percentile rankings improved overall from 2023–24 to 2025–26, but not at every school: Grayhawk gained 10 points, Desert Canyon Middle gained 5, Desert Canyon Elementary gained 2, while Copper Ridge fell 7. The four-school average rose from 84 to 87, though it was 3 points below its 2024–25 peak. School size and student-teacher ratios do not neatly track results: Desert Canyon Elementary has 453 students and a 13.1 ratio, versus Grayhawk’s 408 students and 14.0 ratio, yet Desert Canyon’s averages are about 4 points higher in both subjects; in grades 6–8, Copper Ridge has a lower ratio than Desert Canyon Middle (13.8 versus 15.1) but lower math results. The Online School of Arizona has suppressed test results, and proficiency data cover one year, so the multi-year comparison is based on SchoolDigger rankings rather than test-score trends.
