Summary
Henry A. Coffeen Elementary serves 325 students in kindergarten through grade 5 in Sheridan County School District #2, among nearby schools from both Sheridan County districts. Its 2025–2026 proficiency rates were above Wyoming’s in every reported grade and subject. Its clearest strength is science: fourth-grade proficiency was 82%, compared with 56% statewide and 66% districtwide.
Across grades 3–5, the school averaged 75% in ELA, 83% in math, and 82% in science—about 19, 22, and 26 points above the state, respectively. Its science result also topped the other reported nearby fourth-grade results, which ranged from 47% to 79%; it was 19 points above their average. The school’s advantage over its district was much narrower in ELA and math—about 2 points in each—than in science, where it was 16 points higher. ELA is the most uneven subject: fifth-grade proficiency was 67%, below the district’s 73% but above the state’s 61%. That result was lower than at nearby Sagebrush Elementary, Meadowlark Elementary, and Big Horn Elementary, and about even with Woodland Park Elementary.
