Summary:
Williams Bay Elementary is the only elementary school in the Williams Bay School District, serving grades PK–5 to 282 students in Williams Bay, Wisconsin. Because it is the district's sole elementary campus, there are no other local elementary schools to compare it with, so the most useful comparison is between this school and the state of Wisconsin as a whole — and by that measure, it performs well.
The school has earned 4 stars in each of the three recorded years and has never fallen below the 76th percentile of Wisconsin elementary schools, ranking 237 of 1,039 (77th percentile) in 2025–2026 after a stronger 182 of 1,044 (83rd percentile) in 2024–2025. Math is the clearest strength: in 2025–2026, 3rd grade math was 75.68% proficient, 4th grade 70%, and 5th grade 72.97%, each double digits above state rates in the low 50s. Fourth grade social studies is similarly strong at 82.5%, versus 65.51% statewide, and has stayed in the low 80s for two years.
English language arts remains above state in every tested grade, though the average slipped from about 68.8% to about 64.1% in the latest year. Science is above state but by the narrowest margin — 55% versus 53.46% in 2025–2026 — making it the most likely target for growth. Chronic absenteeism was 13.2%, better than the state's 17.3% but above the district's 11.1%. Per-student spending was $17,291 with a 12.4 student-teacher ratio. Overall, this is a small, stable, top-quartile school with math and social studies strengths and a few areas worth watching.
