Summary:
ZIP code 53549 is home to a single high school — Jefferson High — which serves grades 9–12 with 603 students and is part of the Jefferson School District in Wisconsin. Because it is the only high school in the area, there are no local peer schools to compare it against; instead, its performance can be measured against the district and the state as a whole, and its results largely define the local high-school picture.
Jefferson High's most striking story is a sharp rebound in 2025–2026. The school ranked 200th of 431 schools (54th percentile, 3 stars) in 2023–2024, slipped to 285th of 431 (34th percentile, 2 stars) in 2024–2025, then climbed to 163rd of 533 (69th percentile, 3 stars) in 2025–2026 — a 35-point percentile gain against a larger comparison group. Its 2025–2026 test results were strong: the school exceeded the state proficiency rate in all four reported subjects — Social Studies (59.23% vs. 48.25%), English Language Arts (49.11% vs. 48.47%), Mathematics (46.43% vs. 42.93%), and Science (49.11% vs. 43.20%). That contrasts with 2024–2025, when only Social Studies beat the state. The ACT gains were substantial: Math rose 12.64 points, Science 11.87 points, and ELA 5.66 points, turning three subjects from below the state to above it.
Outcomes are also strong. Jefferson High posted a 95.8% graduation rate in 2024–2025 — matching the district and exceeding the state's 92.0% — with a 0.8% dropout rate, below the state's 1.1% though slightly above the district's 0.6%. Chronic absenteeism was 17.1%, marginally below the state's 17.3% but above the district's 16.3%, making it a metric to watch. About 34.99% of students receive free or reduced lunch, per-pupil spending is $16,791, and the student-teacher ratio is 13.9:1. Overall, the latest data shows a school on an upward path.
