Summary:
Lancaster, Wisconsin is served by the Lancaster Community School District, which contains three public schools covering the full PK–12 span: Winskill Elementary (PK–5, 435 students), Lancaster Middle (6–8, 231 students), and Lancaster High (9–12, 325 students), for a total enrollment of 991. The district ranks 111th of 432 in Wisconsin, placing it in the 74th percentile with 4 stars — but the three schools are moving in very different directions.
Winskill Elementary pairs strong achievement with excellent attendance: 5th-grade math proficiency is 87.5% versus 51.81% statewide, 5th-grade ELA is 82.14% versus 53.63%, and chronic absenteeism is just 5.2%, far below the district's 12.4% and the state's 17.3%. Its rank sits at the 73rd percentile with 4 stars, down from the 86th percentile a year earlier. Lancaster Middle is the clearest improver, climbing from the 55th percentile in 2023–2024 to the 83rd percentile with 4 stars in 2025–2026, with 6th-grade math at 84.13% and 8th-grade social studies at 80.46%. Notably, it achieves this with the lowest per-student spending ($10,693) and the highest student-teacher ratio (15.7) of the three.
Lancaster High shows strong completion outcomes — a 95.2% graduation rate versus 92.0% statewide and a 0.9% dropout rate — and its ACT subjects remain above state averages. However, chronic absenteeism is 20.3%, the only Lancaster rate above the state's 17.3%, and 10th-grade social studies (46.84%) falls below the state (48.25%). Its rank slipped from the 74th to the 60th percentile, dropping from 4 stars to 3 stars. Across all three schools, attendance declines sharply as grade level rises.
