Summary:
Zip code 82426 has one listed high school, Greybull High School, serving grades 9–12; it enrolls 136 students, making it a small-school setting with no nearby school in this list for comparison. Its strongest broad outcome is graduation: 96.7% of students graduated in 2024–25, matching the Big Horn County School District #3 rate and exceeding Wyoming’s 83.1% by 13.6 percentage points.
Because Greybull High School is the only school listed, there is no local top or bottom school; its clearest standout in the latest test results is grade 10 science, where 70.0% were proficient in 2025–26, 16.7 points above the state. Results differ notably by grade and subject: grade 9 ELA and math were 8.0 and 6.6 points above state results, while grade 10 ELA was 9.5 points below and grade 10 math was 3.1 points below. Graduation is a positive indicator, but the latest academic results are mixed rather than uniformly above state levels.
Performance has shifted unevenly: grade 10 science rose 21.5 points from the prior year, while grade 10 ELA fell 12.4 points and math fell 12.7; across the five matched grade-subject results, the school’s average advantage over the state narrowed from 6.28 to 3.74 points. SchoolDigger’s statewide ranking moved from 26th of 80 schools in 2023–24 to 32nd of 81 in 2025–26, and its rating changed from 3 stars to 4 and back to 3. Context figures include a student–teacher ratio of 9, 59.6% of students eligible for free or reduced-price lunch, and spending of $26,699 per student; these describe the school but do not explain its results. Test results cover only grades 9 and 10, and small tested groups may make year-to-year results less steady.
