Summary:
ZIP code 54935 in Fond du Lac, Wisconsin is home to three middle schools — Sabish Middle, Theisen Middle and Woodworth Middle — each serving grades 6–8 as part of the Fond du Lac School District, with a combined enrollment of 1,289 students. The district overall is rated 2 stars, ranking 226th of 432 Wisconsin districts, yet all three of these middle schools earned 3-star ratings in 2025-26 and out-rank their own district.
Theisen Middle has been the historic high performer: it has the best attendance (16.5% chronic absenteeism, below both district and state), the lowest poverty rate (44.55% free/reduced lunch), and the highest scores in the data — 8th grade Math 80.15% and Social Studies 72.06% in 2024-25 — but its composite proficiency slipped from 63.27% to 58.36%. Sabish Middle is now the academic leader (58.94% composite) and the strongest in math (8th grade 68.29%), and the only school with three straight years of rank improvement (50th to 60th percentile), though it has the ZIP's worst absenteeism at 25.5%. Woodworth Middle improved more than anyone (+5.4 points, 49.86% to 55.22%) but still ranks lowest, while spending the most per student ($16,720).
Across the three schools, math is the clear strength, beating the state in every grade band, while 8th grade social studies lags about 6.8 points behind the state — a district-wide pattern — and Science trails slightly. Dropout rates are a non-issue here (0.3%–0.7%, all below district and state). For parents, the biggest shared opportunity is attendance: two of the three schools sit above the state's 17.3% chronic absenteeism rate.
