Summary:
Eight elementary schools with differing grade spans are listed in ZIP code 86004: six are in Flagstaff Unified District, while Pine Forest School and STAR Charter School are in other districts. In 2025–26, the schools’ average all-grades proficiency was 29% in ELA, 12 percentage points below Arizona’s 41%; for the seven schools with reported math results, the average was 24%, 9 points below the state’s 33%. The most important finding is that the area’s overall results fall short of state proficiency levels, particularly in ELA.
Pine Forest stands out in fifth grade, while Thomas M. Knoles and Weitzel’s Puente de Hozho lead in all-grades results. Pine Forest scored 58% in fifth-grade ELA and 68% in math, 20 and 30 points above state rates; its 48% science result was 14 points above the state. Its all-grades results were 40% in ELA and 26% in math, however. Knoles had the highest reported all-grades math result at 33%, matching the state rate, while Puente scored 37% in ELA and 31% in math. At the lower end, W. F. Killip had the lowest reported all-grades ELA result at 21%; Killip and John Q. Thomas each had 17% in math.
SchoolDigger rankings show different recent trajectories: Puente rose from the 30th to the 37th percentile between 2023–24 and 2025–26, and Knoles from the 30th to the 39th, while Sturgeon Cromer fell from the 48th to the 16th percentile. These rankings are not year-to-year test-score changes. Results also differ among similarly sized schools: Killip, with 396 students, had 21% ELA and 17% math, compared with Knoles, with 395 students, at 36% and 33%. STAR’s student-teacher ratio was 4.9 and its ELA result was 22%; Pine Forest’s ratio was 11.9 and its ELA result was 40%. These figures show no simple pattern linking school size or ratio with proficiency.
