Summary:
ZIP code 53811 is home to one public high school: Southwestern Wisconsin High, a small school serving grades 9–12 with 151 students in the rural southwestern Wisconsin community of Hazel Green, part of the Southwestern Wisconsin School District. Because it is the only high school in the area, there is nothing to compare it against locally, so its performance is best judged against state averages and its own past results.
The school's strongest points are graduation and English. Its graduation rate is 96.6%, equal to the district and 4.6 percentage points above the state's 92.0%. Tenth-grade English Language Arts proficiency was 56.76% in 2025–2026 and 56.10% in 2024–2025, both well above state averages of about 48%. Social Studies jumped sharply, from 46.15% (slightly below state) to 63.64%, which is 15.39 points above state. Chronic absenteeism is 14.3%, better than the state's 17.3%, and the school offers a favorable student-teacher ratio of 10.1 with per-student spending of $18,068. About 27.15% of students, roughly 41, qualify for free or reduced lunch.
The main concerns are math and science. In 2024–2025 both were well above state (Math +10.93 points, Science +17.56 points), but in 2025–2026 both fell below state: Math at 37.84% versus 42.93%, and Science at 37.84% versus 43.20%. Those are large one-year drops of 15.82 and 23.14 points. The school's rating slipped from 4 stars at the 75th percentile to 3 stars at the 61st percentile. Chronic absenteeism, while better than state, is higher than the district's 9.2%, and the dropout rate of 1.3% is slightly above the state's 1.1%. With only 151 students, a few students can swing percentages dramatically, so parents should watch whether these trends persist over several years.
