Summary
De Forest High is a public high school serving grades 9–12 in DeForest, Wisconsin, a village just north of Madison, with about 1,137 students in the De Forest Area School District. In 2025–2026 it ranked 190th of 533 Wisconsin high schools — the 64th percentile, or 3 stars — putting it in the middle of the statewide pack.
Among nearby schools, De Forest High trails Waunakee High, Lodi High, and Monona Grove High, is roughly comparable to Sun Prairie East High and Poynette High, and ranks ahead of East High and Madison's smaller alternative schools (Shabazz-City High, Innovative High, Prairie Phoenix Academy). Its 10th-grade proficiency rates are above the state average in social studies, math, and science, but below the state average in English language arts — 47.40% versus 48.47% — making literacy the clearest academic weak spot. The school has also slipped recently, from the 71st percentile in 2024–2025 and the 77th percentile in 2023–2024 to the 64th percentile in 2025–2026, dropping from 4 stars to 3 stars.
Two things stand out for families. First, completion is a real strength: a 96.8% graduation rate and a 0.1% dropout rate, both well above state averages and close to the best nearby districts. Second, chronic absenteeism is a warning sign: 15.6% of students are chronically absent, below the state's 17.3% but well above the district's 9.3% and higher than Lodi, Waunakee, and Poynette. The rate is improving, down from 21.9% in 2022–2023. The school also spends less per student ($15,231) than most nearby high schools and has a higher student-teacher ratio (14.1) than Waunakee, Lodi, Monona Grove, and Poynette. Results also vary across student groups — one bright spot in 2025–2026 was the school's results for African American students at the 94th percentile, while English language learners and Asian students were at the 17th percentile — though small group sizes make these figures volatile.
