Summary
Williams Bay Middle is a small public middle school in Williams Bay, Wisconsin, serving grades 6–8 with 145 students as part of the Williams Bay School District. In 2025–2026 it ranked 385th of 643 ranked middle schools statewide (40th percentile, 2 stars), while its district placed 162nd of 432 districts (62nd percentile, 3 stars), so the middle school sits below its district's overall standing. It fell from the 78th percentile in 2015–2016 to the 27th percentile (1 star) in 2022–2023, recovered to 46th in 2024–2025, then slipped back to 40th.
Results vary sharply by grade. Sixth grade is a bright spot: 70.59% of 6th graders met ELA standards (state: 54.95%) and 64.71% met math standards (state: 53.6%), competitive with higher-ranked neighbors such as Karcher Middle School and Lake Geneva Middle. Seventh-grade ELA was also above state at 62%, but 7th-grade math (52%) was below the state's 55.67%. Eighth grade is the clear weak spot: math proficiency was 26.67% against 53.67% statewide, social studies 46.67% against 64.63%, and science 37.78% against 51.86%. That 8th-grade cohort has been weak in math across years — 35.42% as 6th graders, 31.82% as 7th, and 26.67% as 8th — pointing to a cohort effect, though the weakness has persisted.
The school has favorable inputs: 22.76% of students were eligible for free/reduced lunch in 2024–2025, per-student spending was $17,629, and the student-teacher ratio was 12.1. The dropout rate is effectively 0.0%, and chronic absenteeism of 8.5% is below the district's 11.1% and the state's 17.3%, though Karcher Middle School (3.2%), Elkhorn Area Middle (2.3%), and Lake Geneva Middle (6.1%) are lower. Subgroup results diverge: low-income students rank 41st of 513 (92nd percentile, 5 stars), while female students rank in the 26th percentile (1 star) and male students in the 59th percentile — a gap that has persisted for three years. Overall, the school outperforms Whitewater Middle and Phoenix Middle but trails East Troy Middle, Clinton Junior High, Elkhorn Area Middle, Lake Geneva Middle, and Karcher Middle School. Because enrollment is small, year-to-year results can be volatile.
