Schools in Zip Code 82833

ZIP code 82833 has three schools in Big Horn Elementary (grades K–5), Big Horn Middle School (6–8), and Big Horn High School (9–12), all part of Sheridan County School District #1. Across the 19 reported 2025–26 grade-and-subject results, proficiency was above the Wyoming state result every time. The main exception to that broadly strong picture is relative performance: Middle School eighth-grade science was just 4.2 points above the state and 8.5 points below the district, making it the clearest area to examine closely.

Big Horn High School stands out most consistently in ELA and math: its average advantage over state results was 32.95 points in ELA and 34.25 in math. Big Horn Elementary also performed strongly, averaging 29.07 points above the state in ELA and at least 30.57 in math; its fourth-grade math result was at least 32.4 points above the state. Big Horn Middle School had the smallest average advantage in ELA and math, at 22.57 and 25.13 points, respectively. The high school’s combined ELA/math average was 9.75 points greater than the middle school’s, though these averages cover different grades.

Recent results improved overall relative to the state, but not in every subject: the average gap across the same observations increased by at least 1.57 points from 2024–25 to 2025–26, with ELA up 3.99 and math up at least 1.50, while science fell 4.67. Notable changes include Elementary third-grade ELA rising 15 points and Middle School eighth-grade science falling 15.9 points. SchoolDigger’s 2025–26 statewide rankings place Elementary and High School at #2 in their categories and Middle School at #3; each has remained near the top over the past three years.
