Schools in Zip Code 85248

ZIP code 85248 has eight schools—five elementary, one middle and two high—serving families in an area where every school exceeds Arizona’s all-grades averages in ELA (68% versus 41%) and math (63% versus 33%). That positive area-wide picture masks wide differences: results range from 46% to 86% in ELA and 42% to 88% in math. The most important takeaway is that the gaps between schools—40 points in ELA and 46 in math—make the area average a poor guide to any individual school.

BASIS Chandler and Chandler Traditional Academy–Independence lead in ELA at 86%; BASIS Chandler leads in math at 88%, followed by CTA Independence at 85%. BASIS Chandler Primary–South Campus is also strong, at 83% ELA and 80% math. At the lower end, Basha Elementary has 46% ELA and 42% math, while Bogle Junior High also has 42% math and 53% ELA. Basha’s ELA is 25 points below the other schools’ average; Basha and Bogle’s math is 28 points below the other six schools’ average. Both schools are still above state averages in these all-grades subjects.

Science results add important contrasts: fifth-grade proficiency is 69% at BASIS Chandler and 68% at CTA Independence, but 30% at Anna Marie Jacobson Elementary and 32% at Basha, below the state’s 34%. BASIS Chandler also leads in eighth-grade science (92% versus Bogle’s 43%) and 11th-grade science (98% versus Hamilton High School at 45%). SchoolDigger’s average percentile across seven schools with comparable histories rose by about 2 points from 2023–24 to 2025–26; Ira A. Fulton Elementary rose 7 points, while Basha fell 2. SchoolDigger’s latest supplied rankings include CTA Independence at 6th of 900 and BASIS Chandler Primary–South at 12th of 900. Enrollment and student–teacher ratios do not form a simple performance pattern: Hamilton has 3,444 students and a 20.3 ratio, while Fulton has a 14.9 ratio but does not lead in scores. School spans differ, and free/reduced-lunch figures are unavailable, limiting like-for-like and income-context comparisons.
