Summary:
Zip code 86305 has two schools in the Prescott Unified District: Granite Mountain Upper Elementary School, serving grades K–8, and Abia Judd Elementary School, serving K–5. In 2025–26, both schools’ all-grades English language arts (ELA) and math results were above state figures. Their unweighted average was 52% in ELA and 48% in math, compared with state results of 41% and 33%. The clearest headline is that Abia Judd had the higher all-grades proficiency in both subjects.
Abia Judd leads with 59% proficient in ELA and 56% in math, ahead of Granite Mountain by 14 and 16 percentage points, respectively. Abia is also 18 points above the state in ELA and 23 points above in math. Granite Mountain’s results are lower than Abia’s, but still exceed the state by 4 points in ELA and 7 in math. At the grade level, Abia’s third-grade math result stands out at 67%, compared with 38% statewide; its fourth-grade math result is a relative dip at 47%, below the district’s 51% but above the state’s 40%.
SchoolDigger’s statewide percentile ranking rose for Abia, from 67 in 2023–24 to 77 in 2025–26, while Granite Mountain’s moved from 60 to 57, including a 7-point drop in the latest year. Abia has 471 students and a 14.7 student–teacher ratio; Granite Mountain has 512 students and a 17.1 ratio. Granite Mountain also recorded 45% proficiency in fifth-grade science, matching the district and exceeding the state’s 34%; no Abia science result is available. Because the schools serve different grade spans and have no tested grade in common, the schoolwide results are not a like-for-like comparison, and SchoolDigger ranking trends do not show changes in test proficiency.
