Summary:
ZIP code 82833 has one listed high school, Big Horn High School, serving grades 9–12 and enrolling 169 students. Its reported student–teacher ratio was 12.4 in 2024–2025. The most important finding for parents is that Big Horn’s 2025–2026 proficiency rates were well above Wyoming’s in every reported test: by 30.1 to 35.8 percentage points across English language arts, math and grade 10 science.
There is no second school in the list to rank above or below Big Horn, so the data show no within-area school comparison. Big Horn’s five 2025–2026 proficiency results ranged from 78.6% in grade 10 math to 90.5% in grade 10 ELA; the matching state results ranged from 45.0% to 55.6%. SchoolDigger ranked Big Horn 2nd of 81 Wyoming high schools, in the 98th percentile, in 2025–2026. Its 2024–2025 graduation rate was 90.0%, above both Sheridan County School District #1 at 82.4% and Wyoming at 83.1%. These results make the sole listed school a strong performer on the available measures.
Overall proficiency improved between the two years, but not in every subject and grade: Big Horn’s average across the five matched tests rose from 79.7% to 84.32%, while the state average rose from 48.16% to 51.02%. The biggest school gains were 11.8 points in grade 9 math and 10.5 points in grade 10 ELA; grade 9 ELA fell 3.2 points and grade 10 math fell 3.9. SchoolDigger ranked Big Horn 1st of 80 in 2023–2024, then 2nd of 83 and 2nd of 81 in the following two years. The reported low-income measure was 11.2% eligible for free or reduced-price lunch in 2022–2023; it is context, not an explanation of results. Because only one school is listed, parents cannot compare schools within the ZIP code.
