Summary:
ZIP code 53191 is served by a single middle school — Williams Bay Middle — which enrolls about 145 students in grades 6 through 8 as part of the Williams Bay School District. Because it is the only middle school in the area, there is no side-by-side local comparison to make, so the school's own profile stands alone. It reported a dropout rate of 0.0% for 2024–2025, chronic absenteeism of 8.5%, free/reduced-price lunch at 22.76%, per-student spending of $17,629, and a student-teacher ratio of 12.1.
Williams Bay Middle's clearest strengths are attendance and its lower grade levels. Its 8.5% chronic absenteeism rate is below the district's 11.1% and well below the state's 17.3% — less than half the statewide figure. In 2025–2026, 6th-grade English language arts (70.59%) and math (64.71%) were both comfortably above state averages of 54.95% and 53.60%, and 7th-grade ELA (62%) topped the state's 55.33%. Seventh-grade math also improved sharply from the prior year, though at 52% it stayed slightly under the state's 55.67%.
The main concern is 8th grade, where results fell below state in every tested subject. Eighth-grade math was 26.67% proficient against 53.67% statewide — a gap of about 27 percentage points and a 15.33-point drop from the year before. Eighth-grade social studies slid to 46.67% from 78%, and science came in at 37.78%. The school ranked 385 of 643 statewide (40th percentile, 2 stars) in 2025–2026, while the Williams Bay School District ranked 162 of 432 (62nd percentile, 3 stars). With roughly 48 students per grade, percentages can swing widely year to year, so single-year changes — especially in 8th grade — should be read with caution.
