Pewaukee School District

Pewaukee School District is a four-school, PK–12 district in Wisconsin serving 2,907 students, and it stands out as one of the state's strongest systems — ranked 26th of 432 districts, in the 94th percentile, with a 5-star district rating. Each grade span is served by a single school, so the pipeline is clean: Pewaukee Lake Elementary (PK–2, 748 students), Horizon School (3–5, 647), Asa Clark Middle (6–8, 623), and Pewaukee High (9–12, 889). Pewaukee High is the academic flagship: 20th of 533 schools (96th percentile, 5 stars), a 98.1% graduation rate, and 10th-grade ACT proficiency roughly 29–33 points above the state in ELA, Science, and Math. Horizon School is the district's biggest riser, climbing from 129th of 1,044 with 4 stars to 85th of 1,039 with 5 stars, and posting the highest reported 2025–2026 score in the data — 87.5% in 4th-grade Social Studies. Asa Clark Middle remains strong in math (83.81% in 7th grade) but slipped from 5 stars to 4 stars, with 8th-grade Math, Science, and Social Studies all declining. Pewaukee Lake Elementary has no state test data because it serves PK–2, but it has the district's smallest classes (14.2 students per teacher). District-wide, chronic absenteeism is 7.9% — less than half Wisconsin's 17.3%. Horizon School is lowest at 5.5%, followed by Pewaukee Lake Elementary at 6.2% and Asa Clark Middle at 7.1%; Pewaukee High is highest at 11.3%, still well below the state. Low-income enrollment is tightly clustered (10.80%–11.63%) and spending ranges from $12,272 to $15,450 per student. The areas to watch are the high school's Social Studies decline and Asa Clark's recent softening in math and science.
