Summary:
Williams Bay High is the only public high school in the Williams Bay School District, serving grades 9–12 to about 170 students — roughly 40 per grade level — at 500 W Geneva St in Williams Bay, Wisconsin. Because there is just one high school here, the district-level figures in this data are essentially a mirror of the school's own, so any small school-versus-district gap is a rounding or small-cohort artifact rather than a comparison between campuses.
The school has climbed sharply in state rankings: from 279 of 431 schools and 2 stars in 2023-2024, to 132 of 431 and 3 stars in 2024-2025, and to 136 of 533 — the 74th percentile and 4 stars — in 2025-2026. Reading and social studies are its clearest strengths. In the most recent year, 10th graders scored 67.5% proficient in ACT English Language Arts against 48.47% statewide, and 68.57% in Forward Exam Social Studies against 48.25% statewide. Completion and attendance are similarly strong: a 100.0% graduation rate versus 92.0% statewide, a 0.5% dropout rate versus 1.1%, and 10.2% chronic absenteeism versus 17.3% statewide.
Math and science tell a different story. Math came in at 42.5% proficient, essentially level with the state's 42.93%, and science fell from 52.27% to 40% — moving from above the state to slightly below it. With only a few dozen tested students, year-to-year swings can reflect just two or three students, so these shifts are worth monitoring rather than treating as settled trends. Resources are above average, with $20,097 in per-student spending and a 12.4 student-teacher ratio, while 31.76% of students qualify for free or reduced lunch. Overall, this is a small, well-funded school with outstanding reading and social studies results, near-perfect completion rates, and room to grow in math and science.
