Summary:
ZIP code 54630 is home to exactly one public high school, Galesville-Ettrick-Trempealeau High, which serves grades 9–12 and enrolls 411 students in Galesville, Wisconsin, as part of the Galesville-Ettrick-Trempealeau School District. Because there is only one high school in this ZIP code, there are no local head-to-head comparisons to make; the school is best measured against Wisconsin state averages and its own past results. In 2025–2026 it ranked 146th of 533 Wisconsin high schools, placing it at the 73rd percentile with 4 stars, and its district ranked 116th of 432, also at the 73rd percentile with 4 stars.
Academically, the school's 2025–2026 10th-grade ACT results were strong: 57.84% proficient in English Language Arts versus 48.47% statewide, 49.02% in Mathematics versus 42.93%, and 53.92% in Science versus 43.20%. Social Studies on the Forward Exam was the exception at 47.87%, essentially level with the state's 48.25% and down 4.61 points from 52.48% the prior year. Year over year, ELA rose 13.16 points, Mathematics 5.40 points and Science 10.30 points, mirroring a rebound from 46th percentile / 2 stars in 2024–2025 to 73rd percentile / 4 stars in 2025–2026.
Outcomes in attendance and completion are exceptional: a 99.0% graduation rate and 0.0% dropout rate in 2024–2025, compared with 92.0% and 1.1% statewide, plus 3.7% chronic absenteeism against 17.3% statewide. Per-student spending is $17,618 and the student-teacher ratio is 12.9:1. The main caution for families is volatility — the school moved from the 73rd percentile to the 46th and back to the 73rd over three years — so one strong year does not yet establish a long-term trend.
