Big Horn County School District #3

Big Horn County School District #3 serves 447 students across three schools in Big Horn County, Wyoming, covering PK–12. In 2025–26, results were mixed: across reported grades, ELA proficiency was about level with Wyoming’s results, while math and science were below. The clearest concern is math, where results averaged 49.8% compared with 55.0% statewide, and grade 4 at Greybull Elementary was especially low at 31.3% versus 62.6% statewide.

Greybull Middle School stands out for ELA: its grades 6–8 average was 62.0%, 2.6 percentage points above the matched state average, led by grade 8 at 72.2% versus 60.9%. Greybull High School had the strongest average math results, 47.5% versus 45.8% statewide, and a notable grade 10 science result of 70.0%, 16.7 points above Wyoming. Its 2024–25 graduation rate was also strong at 96.7%, compared with 83.1% statewide. The most pronounced weakness was elementary grade 4: ELA was 28.1% versus 52.6% statewide, while math was 31.3% versus 62.6%. Elementary results were not uniformly low, however: grade 5 ELA reached 76.9%, 15.6 points above the state.

Recent changes make math a particular area to watch: from 2024–25 to 2025–26, school math results fell by an average of 8.4 points across reported grades while state results rose 4.1 points. ELA moved in a more positive direction, with school results up an average of 2.9 points, though middle- and high-school ELA declined. SchoolDigger’s latest rankings place the high school 32nd of 81 (3 stars), the middle school 46th of 76 (2 stars), and the elementary school 107th of 148 (1 star); all ranked lower than in 2023–24. Context measures differ too: student-teacher ratios range from 9.0 at the high school to 12.7 at the middle school, and reported free/reduced-lunch eligibility ranges from 54.8% at the middle school to 63.3% at the elementary school. These figures offer context, not an explanation for school results.
