Summary
Williams Bay High is a small public high school serving roughly 170 students in grades 9–12 in Williams Bay, Wisconsin, part of the Williams Bay School District, which ranks 162 of 432 districts statewide while the high school itself ranked 136 of 533 high schools in 2025–2026 (74th percentile, four stars). Families considering it will find a school that combines small size, high per-pupil spending ($20,097), and a low student-teacher ratio (12.4) with strong completion metrics: a 100% graduation rate, a 0.5% dropout rate, and 10.2% chronic absenteeism, all better than state averages (92.0%, 1.1%, and 17.3%). Chronic absenteeism has fallen steadily from 29.2% in 2021–2022 to 10.2% in 2024–2025.
Academically, the school's signature is the humanities. In 2025–2026, 10th-grade proficiency was 68.57% in social studies and 67.50% in English language arts — the highest among nearby schools and far above state rates (48.25% and 48.47%). Math (42.50%) was essentially at the state level (42.93%), while science (40.00%) was below both the state (43.20%) and several neighbors. East Troy High outperformed Williams Bay in math (57.58%) and science (59.60%), while Williams Bay led in ELA and social studies. Big Foot High, only about 3.8 miles away, beat Williams Bay in science (48.78%) but trailed in social studies, ELA, and math.
One of the most distinctive patterns is how well the school serves students from low-income families: the low-SES subgroup ranked in the 88th percentile in 2024–2025 and the 84th percentile in 2023–2024, both four-star results. Rankings have been volatile, however — from the 92nd percentile in 2015–2016 down to the 35th percentile in 2022–2023 and 2023–2024, then back up to 74th in 2025–2026. With only 170 students, a handful of students can shift percentages by several points, so multi-year trends are more informative than any single year. Compared with nearby schools such as Clinton Senior High and Delavan-Darien High, Williams Bay shows higher proficiency, better attendance, and stronger graduation outcomes.
