Summary:
ZIP code 54935 covers Fond du Lac, Wisconsin and is home to 14 schools — 9 elementary, 3 middle, and 2 high schools — all within the Fond du Lac School District, which ranks 226 of 432 districts statewide (48th percentile, 2 stars). Combined enrollment is 6,226 students, from Fond du Lac High at 1,917 students down to Fond du Lac STEM Academy at 162 students in grades 6–12.
Lakeshore Elementary is the clear standout: a 5-star school ranked 12th of 1,039 Wisconsin elementary schools in 2025–26 and in the top 1–2% for three straight years, with math proficiency of 93.22% in 4th grade versus 52.87% statewide, plus the lowest chronic absenteeism (4.8%) and lowest free/reduced lunch rate (16.1%) in the ZIP. Roberts Elementary is the biggest upward mover, rising from the 44th to the 78th percentile and from 2 to 4 stars. STEM Academy is 4 stars and 84th percentile with strong ACT results, though its small size makes year-to-year scores volatile. Sabish Middle and Theisen Middle post above-state math results.
The clearest challenges sit at Parkside Elementary (15th percentile, 1 star, 79.38% free/reduced lunch), Pier Elementary (22nd percentile), and Chegwin Elementary, which is improving but from a low base. Chronic absenteeism splits the group sharply — under 10% at Lakeshore, Riverside, Waters, and Rosenow, but above 23% at Sabish, Pier, Chegwin, and Fond du Lac High. Notably, spending does not track achievement here: Lakeshore has the lowest per-pupil spending ($14,180), while the highest-spending schools rank in the 32nd and 46th percentiles.
