Summary
Old Mill Elementary School serves 591 students in prekindergarten through grade 5 in Mount Washington, in Bullitt County. Its results are mixed: it stands out in writing and fourth-grade math, but reading, science, and fifth-grade math are weaker. The central concern is that its overall standing and results across several subjects have declined in recent years.
Writing is the clearest strength compared with the state, district, and nearby schools: Old Mill’s grade 5 score was 42%, versus 35% statewide, 27% in the district, and a nearby-school average of 37%. Mathematics averaged 45% across grades 3–5, above the state’s 43% and the district’s 39%, but below the nearby average of 47%. That average hides a large grade-level split: fourth-grade math was 59%, 16 points above the state, while fifth-grade math was 33%, 10 points below it. Reading averaged 46%, below the state’s 50% and nearby schools’ 51%; science was 34%, compared with 40% statewide and 40% nearby. Old Mill’s chronic absenteeism rate, 13% in 2025–2026, was below the nearby average of 15%.
Old Mill is at the 47th statewide percentile with 2 stars in the latest SchoolDigger rankings, down from the 85th percentile and 4 stars in 2021–2022. From 2022–2023 to 2025–2026, average proficiency fell 10 points in math and 12 in reading; science, writing, social studies, and editing and mechanics also declined over that period. Its student–teacher ratio was 17.9:1 in 2024–2025, compared with a nearby-school average of 16.9:1. In 2024–2025, 33% of students were free/reduced lunch eligible, below the nearby average of 46%; these figures are context, not an explanation for results. SchoolDigger’s ranking for Low Socio Economic Status Students was at the 25th percentile in 2025–2026, compared with 47 overall, and fell from the 51st percentile in 2023–2024. Its Female Students ranking also dropped sharply, from the 81st percentile to the 38th over those years.
