Summary:
Sublette County School District #9 has one middle school in this list: Big Piney Middle School, which serves grades 6–8 and enrolls 105 students. Since it is the only school listed, parents can compare its results with state results and look at differences among grades, but not compare it with another local middle school. The clearest concern is mathematics: in 2025–2026, proficiency averaged 40.5% across grades 6–8, 14.1 percentage points below the state average of 54.6%.
Within the school, grade 8 ELA stands out positively: 63.0% were proficient, 2.1 points above the state result. Grade 7 ELA is the sharpest weak spot, at 38.7%—17.8 points below the state’s 56.5%; grade 6 ELA was close to the state, just 0.3 points higher. Math was below the state in all three grades: by 18.0 points in grade 6, 11.0 in grade 7 and 13.2 in grade 8. Grade 8 science was closer to the state, with 46.4% proficient compared with 48.1%. ELA also varies considerably by grade, spanning 24.3 points from grade 7 to grade 8.
Results moved farther behind the state in the latest year-to-year comparison, although individual grades did not all follow the same pattern. Big Piney’s average ELA result fell from 60.3% to 54.3%, while the state average stayed near 59.4%; its math average fell from 45.7% to 40.5% as the state rose from 50.0% to 54.6%. Grade 8 science declined from 52.9% to 46.4%, while the state fell more modestly, from 49.3% to 48.1%. SchoolDigger ranked the school 58th of 76 schools, at the 24th percentile, in 2025–2026, compared with 40th of 77 at the 48th percentile the prior year. Context measures include an 11:1 student-teacher ratio and 42.9% eligible for free or reduced-price lunch in 2024–2025; these describe the school but do not explain its results. With only one school listed, there is no local school-to-school comparison.
