Gilbert Unified District

Gilbert Unified District includes 38 schools—26 elementary, five middle and seven high schools—in Gilbert, Arizona. Across the 37 schools with reported results, average proficiency was 58% in ELA and 52% in math, compared with statewide rates of 41% and 33%. The biggest takeaway for families is that these averages hide a wide gap between schools: the strongest and weakest reported results differ by 62 percentage points in ELA and 55 points in math.

Gilbert Classical Academy 7-12 stands out at 91% ELA and 83% math; SchoolDigger ranks it first among 256 Arizona high schools. Among elementary schools, Neely Traditional Academy leads with 82% ELA and 78% math and ranks 18th among 900 elementary schools. Highland Junior High and Greenfield Junior High lead middle schools in ELA at 61% and 60%; Highland also leads in math at 56%. At the low end, Harris Elementary School has 29% ELA and Burk Elementary School has 28% math—below state rates by 12 and 5 points. Classical also leads in 11th grade, outperforming the other five high schools’ averages by about 48 points in ELA, 51 in math and 47 in science.

SchoolDigger ranking histories show improvement for many elementary and middle schools, though not all: the elementary average rose from 70 to 74 percentile points from 2023–24 to 2025–26, and the middle-school average rose from 70 to 77. Carol Rae Ranch Elementary gained 15 percentile points, while Burk fell 15; South Valley Junior High fell 7. Enrollment and student-teacher ratios do not neatly track results: Neely reports 805 students and a 16.3-to-1 ratio, while Harris has 383 students and a 10.8-to-1 ratio but much lower ELA proficiency. Free/reduced-lunch data are unavailable, so that measure cannot help distinguish schools.
