Summary:
ZIP code 84021 contains one high school, Duchesne High, a small school serving grades 7–12 with 408 students in the rural Duchesne area. The school is part of the Duchesne District, which ranks 67th out of 92 Utah districts. Because it is the only high school in the ZIP code, families cannot compare it with another nearby high school in the same area. Instead, the most useful comparisons are with district and statewide results.
Duchesne High has several encouraging academic results, especially in eighth grade. In 2025–2026, 62.8% of eighth-graders were proficient in science, well above both the district and Utah averages. Eighth-grade English language arts was also strong at 47.7%, exceeding both comparisons, while eighth-grade math was above the state average but slightly below the district. High-school English language arts is another relative strength: ninth-grade performance was higher than the district, and the reported tenth-grade range was also above the district result. The school’s 84.8% graduation rate was 3.2 percentage points higher than the district, although it remained below the statewide rate of 89.8%.
Results are more concerning in several other areas. Seventh-grade math and science proficiency were both 24.6%, well below statewide results, and high-school math remains the clearest academic challenge. Ninth-grade math proficiency was 21.9%, compared with 39.4% statewide, while high-school science also trailed Utah results. The school’s 15.2% dropout rate was close to the district rate but substantially higher than the state rate, and chronic absenteeism affected 27.3% of students, above the statewide figure. The school ranked in the 13th percentile statewide in 2025–2026, a slight improvement from the prior year but still low overall. Parents may want to focus on the school’s strong eighth-grade outcomes and graduation rate while asking about plans to improve attendance, reduce dropouts, and strengthen math and science instruction.
