Summary:
ZIP code 54139 has one public high school, Lena High, serving grades 9–12 in Lena, Wisconsin, with 124 students in the Lena School District; because it is the only high school in the area, the most useful comparisons are to Wisconsin statewide results and to the school’s own prior-year performance.
Lena High shows clear strengths and some uneven results. Its graduation rate is 94.8%, above Wisconsin’s 92.0%. In 2025–2026, 10th-grade ACT English Language Arts proficiency was 58.33% versus 48.47% statewide, and ACT Science was 50% versus 43.2% statewide. Chronic absenteeism is 15.4%, below the state’s 17.3% but more than double the district’s 7.5%; the dropout rate is 1.6%, slightly above the district’s 1.0% and the state’s 1.1%. Social Studies proficiency was 35.48% versus 48.25% statewide, and math was 37.5% versus 42.93%, down from 48.15% the prior year. The school’s accountability trend is positive: it improved from 2 stars and the 33rd percentile in 2024–2025 to 3 stars and the 51st percentile in 2025–2026, while the district is ranked 300th of 432, at the 31st percentile with 2 stars.
For parents, the key context is that this is a small school: 124 students, a 10.7:1 student-teacher ratio, 29.03% free/reduced lunch, and $17,217 per-student spending. At this size, a few students can shift proficiency percentages several points, so multi-year trends are more reliable than a single year’s number. Overall, Lena High is improving, with strong graduation, ELA, and science outcomes, but social studies, recent math performance, and attendance-related measures are areas to watch.
