Summary
Fond du Lac High is a large public high school serving grades 9–12 in Fond du Lac, Wisconsin, a mid-sized city in the Fox Valley, and with 1,917 students it is by far the biggest school in its local comparison group. It belongs to the Fond du Lac School District, which ranks 226th of 432 districts in Wisconsin (48th percentile, 2 stars). In 2025–2026, the school ranked 258th of 533 high schools statewide (52nd percentile, 3 stars) — a big jump from 2024–2025, when it placed 324th of 431 (25th percentile, 1 star), and its best result since 2020–2021.
Its test-score profile is mixed. Social Studies is a clear strength at 57.66% proficiency, well above the state's 48.25%. ELA (46.89%) and Math (42.49%) are essentially at the state average (48.47% and 42.93%). Science is the weak spot: 33.16%, about 10 points below the state's 43.20%, and lower than nearly every nearby school except North High and Horace Mann High. Fond du Lac STEM Academy, West High, Campbellsport High, Lomira High, Laconia High, and Oakfield High all score higher in Science.
Outcomes are also a blend. The 93.0% graduation rate tops the district (92.8%) and state (92.0%), but the 1.7% dropout rate is above the state's 1.1%, and chronic absenteeism of 23.4% is higher than the district (18.2%), the state (17.3%), and most nearby schools — only North High (26.2%) is higher. On the positive side, English Language Learner students rank in the top 7% of schools statewide for effectiveness, and students in special education and from low-income families also rank above the school's overall percentile, with low-income results climbing from the 19th percentile a year earlier. Note the context: 42.72% of students qualify for free/reduced lunch and the student-teacher ratio of 16.5 is the highest among nearby schools, compared with much lower poverty rates in smaller nearby districts like Lomira, Laconia, and Oakfield.
