Best Public Schools in Mills, WY

Mills, Wyoming, has one listed school, Wyoming Classical Academy, which serves grades K–8 and has 298 students. With no other listed Mills schools, its results are the only local results available to families. In 2025–2026, the school’s unweighted average proficiency was above the state average in ELA and math across grades 3–8, and in science across the two reported grades. The most important takeaway is that overall results are favorable relative to the state, but vary considerably by grade.

Grade 8 stands out at the top: students were proficient at 88.5% in both ELA and math, respectively 27.6 and 34.6 percentage points above state results. Grade 3 was the clearest weak spot, with 40.5% proficient in ELA and 42.9% in math—15.2 and 18.3 points below the state. The school’s unweighted averages were 68.0% in ELA versus 58.0% statewide and 63.5% in math versus 58.1%. Science results were also above state levels in both reported grades: 66.7% in grade 4 and 76.0% in grade 8. These contrasts mean a school-wide average may not reflect the experience or results in a particular grade.

Matched-grade averages improved relative to the state between 2024–2025 and 2025–2026: the school’s ELA lead grew from 0.9 to 6.5 points, while its math average moved from 5.5 points below the state to 0.5 points below. Grade-5 math was an especially large change, rising from 26.9% to 76.7%; this year-to-year comparison does not track the same students. SchoolDigger’s ranking improved from 108th of 147 schools (27th percentile, 1 star) in 2023–2024 to 73rd of 148 (51st percentile, 3 stars) in 2025–2026.
