Summary:
Schools in ZIP code 86323 include five schools, from early childhood and elementary grades through middle and high school. Across schools with reported all-grades results, the average is 35% proficient in English language arts (ELA), compared with 41% statewide, and 19% in math, compared with 33% statewide. The clearest area-wide concern is math: the reported school average is 14 percentage points below the state rate, a larger shortfall than in ELA.
Del Rio Elementary School has the strongest reported all-grades results: 43% in ELA, 2 points above the state, and 25% in math, though still 8 points below the state. Heritage Middle School has the lowest reported all-grades math result, 13%—20 points below the state—and its 8th-grade math result is 8%, compared with 30% statewide. Mingus Springs Charter School pairs the lowest reported all-grades ELA result, 26%, with the area’s highest supplied 5th-grade science result: 58%, versus 34% statewide. At Chino Valley High School, 11th-grade math is 20% versus 31% statewide, while graduation is a relative strength: 89% versus 80% statewide.
Recent SchoolDigger rankings show mixed movement, not a clear upward trend: from 2024–25 to 2025–26, Chino Valley High School rose 8 percentile points to the 41st percentile, Heritage Middle School rose 3 points to the 24th, and Del Rio Elementary School fell 7 points to the 40th; the three-school average rose just 1 point. These are ranking changes, not test-score changes. Ratios range from 16.7 to 26.2 students per teacher, but the figures do not show a simple link between ratios or enrollment and results; free/reduced-lunch rates are not reported. Grade spans differ, and some test scores are suppressed, so the results do not support a complete like-for-like comparison of every school.
