Summary:
ZIP code 54448 is served by a single middle school: Marathon Venture Academy, located at 100 Spring Valley Dr in Marathon, WI. It serves grades 6–8 with 173 students and belongs to the Marathon City School District. With a 15:1 student-teacher ratio, per-student spending of $11,172, and 26.59% of students qualifying for free or reduced lunch, the school has modest class sizes and a moderate poverty rate. One important data note for parents: the district's test results mirror the school's results in every reported grade and subject, so comparing the school to the state is far more useful than comparing it to its own district.
Eighth grade is the clearest strength. In 2025–2026, 8th graders scored 72.73% proficient in science, 78.18% in social studies, 74.55% in math, and 58.18% in ELA — all above state averages, with science and math roughly 21 points ahead. Every 8th grade subject improved year over year, including a 31-point jump in math. The picture is weaker in the lower grades. Sixth grade ELA (43.10%) and math (45.61%) both trail the state, and 7th grade ELA fell sharply from 66.67% to 40.82% — a 25.85-point drop that moved it from well above to well below state. Seventh grade math also declined to 59.18%, though it remains slightly above state.
Overall, the school outperformed the state on a simple average of its eight reported tests (59.04% vs 55.51%) and was above state in five of eight tests, up from three the prior year. Attendance is a real strength: chronic absenteeism is 12.2%, below both the district (14.2%) and state (17.3%), and the dropout rate is 0.0%. The school ranks 268 of 643 (58th percentile, 3 stars), an improvement over 2024–2025 but still below its 2023–2024 result of 176 of 641 (73rd percentile, 4 stars).
