Summary:
Zip code 85540 has one high school, Morenci High School, serving grades 9–12 with 361 students. There are no other listed high schools for families to compare locally. In 2025–2026, Morenci’s all-grades proficiency was 28% in English language arts (ELA) and 18% in mathematics, compared with 41% and 33% statewide. The most important finding is that Morenci’s results are below the state level in both subjects, with the larger gap in mathematics.
Morenci is both the highest- and lowest-performing school in this list because it is the only one, so comparisons with state and district results are more informative. In 11th grade, ELA proficiency was 28%, 10 percentage points below the state’s 38%; mathematics was 18%, 13 points below the state’s 31%. The Morenci Unified District reported the same 11th-grade results as the school in both subjects. Science was a positive exception: in 2024–2025, Morenci’s 11th-grade proficiency was 22%, 3 points above the state’s 19%, and equal to the district’s.
SchoolDigger’s ranking percentile rose from 34 in 2023–2024 to 40 in 2024–2025, then fell to 29 in 2025–2026—a net decline of 5 percentile points over the period. The school has a student–teacher ratio of 6.8, and its free/reduced-lunch figure is not reported. Morenci’s reported graduation rate was 96% in 2021–2022, versus 80% statewide in 2024–2025; its dropout rate was 4% in 2022–2023, versus 5% statewide in 2024–2025. Because there is only one listed school and the graduation and dropout figures come from different years, these data do not allow a local school-to-school comparison or a same-year school–state comparison for those rates.
