Summary:
Williams Bay Elementary is the only elementary school in ZIP code 53191, serving grades PK–5 with 282 students as part of the Williams Bay School District in a small lakeside community in Walworth County. Because it is the sole elementary school in the area, parents have a single option to consider, and the most useful comparisons are between this school and statewide averages, as well as year-over-year trends.
The school's academic results are consistently strong. It earned 4 stars in each of the last three school-rank years and placed between the 76th and 83rd percentiles among roughly 1,040 Wisconsin schools, peaking in 2024–2025 at 182 of 1,044. On the Forward Exam, it exceeded the state proficiency rate in every reported subject and grade in both 2025–2026 and 2024–2025. Mathematics is the standout: grades 3–5 averaged about 72.9% proficiency in 2025–2026 versus roughly 53.1% statewide, a gap of nearly 20 points. Fourth-grade social studies is similarly impressive at 82.50% (2025–2026) and 81.08% (2024–2025), each about 17 points above the state. Science is only modestly above the state, at 55.00% versus 53.46% most recently. Note that school and district proficiency figures are identical at each grade and subject, so the statewide comparison is the more informative one.
Attendance is mixed: chronic absenteeism of 13.2% is 4.1 points below the state's 17.3% but 2.1 points above the district's 11.1%, making it a possible area for improvement. Context includes 22.7% free/reduced lunch eligibility, $17,291 per-student spending, and a 12.4 student/teacher ratio, though no state benchmarks are provided for spending or staffing. Year-over-year scores moved in both directions, which is expected with small grade-level cohorts and should be interpreted cautiously rather than as a trend.
