Summary:
Zip code 83113 has one elementary school, Big Piney Elementary, serving kindergarten through grade 5 and enrolling 138 students. Its tested-grade results are mixed: English language arts (ELA) is stronger overall than mathematics, while grade 4 science is the clearest area of concern, at 33.3% proficient compared with 56.2% statewide.
There is no meaningful local top-to-bottom comparison because Big Piney is the only school in the list. Within the school’s 2025–2026 results, ELA grades 3 and 5 stand out positively: 64.7% and 69.7% proficient, respectively, or 9.0 and 8.4 percentage points above state results. Grade 4 science is the lowest result and trails the state by 22.9 points; grade 4 mathematics is also notably low at 44.4%, 18.2 points below the state. Across all three tested grades, the equally weighted ELA average was 3.1 points above the state average, while the mathematics average was 11.0 points below.
Results improved notably in ELA and mathematics over the latest year, but science moved in the opposite direction. Big Piney’s ELA average rose from 38.8% to 59.6%, and its mathematics average rose from 39.4% to 50.6%; grade 4 science fell from 37.8% to 33.3%, widening its gap with the state. SchoolDigger ranks Big Piney 109th of 148 Wyoming elementary schools, in the 26th percentile, with 1 star for 2025–2026; its ranking improved from 132nd of 149 and the 11th percentile the prior year. The reported student-teacher ratio is 7.8 for 2024–2025, and 50.7% of students were eligible for free or reduced-price lunch that year; these figures provide context, not an explanation of results. Because the list includes only one school, it cannot show how Big Piney compares with other nearby schools.
