Summary:
ZIP code 82833 has one middle school, Big Horn Middle School, serving grades 6–8 with 134 students. For parents comparing options, the clearest finding is that Big Horn’s 2025–2026 proficiency was well above Wyoming’s in both English language arts (ELA) and math, across all three grades.
There is no other middle school listed in the ZIP code, so Big Horn is both the highest- and lowest-performing local option by default. Its results compare favorably with the state: average ELA proficiency across grades 6–8 was 82.0%, versus 59.4% statewide, and math averaged 79.7%, versus 54.6%. In grade 8 science, however, Big Horn’s 52.3% was closer to the state’s 48.1% and below the 60.8% reported for Sheridan County School District #1. Science is therefore a relative weak spot compared with the school’s stronger ELA and math results.
Results over time show continued strength, but different patterns by subject: ELA average proficiency rose from 80.5% in 2024–2025 to 82.0% in 2025–2026, while math slipped from 80.3% to 79.7% and grade 8 science fell from 68.2% to 52.3%. Big Horn nevertheless remained ahead of the state in all three subjects in 2025–2026. SchoolDigger ranked it 3rd of 76 schools statewide that year, following 2nd of 77 the prior year, and lists the district at 3rd of 44 with five stars. The school’s reported student-teacher ratio is 11.7, and 10.5% of students were eligible for free or reduced-price lunch in 2022–2023; these are useful context measures, not explanations for test results. With only one school listed, the data cannot support comparisons among local schools.
