Summary:
ZIP code 54546 is served by a single school: Mellen Public School, the only school in the Mellen School District, serving students in grades PK–12 in this small northern Wisconsin community. The school enrolls 252 students and is classified as an Alternative school, with 45.63% of students qualifying for free or reduced lunch. It spends $16,186 per student and has a student-teacher ratio of 12.4 — figures typical of small rural districts where fixed costs are spread across fewer students. Because it is the only school in the district, all district-level results mirror the school's results exactly.
The strongest results are in attendance and completion. In 2024–2025 the graduation rate was 100.0% (state: 92.0%), the dropout rate was 0.0% (state: 1.1%), and chronic absenteeism was 12.4% (state: 17.3%). Early math is a repeatable bright spot: 4th-grade math (56.25%) and 5th-grade math (58.82%) both exceeded the state in 2025–2026, as they also did in 2024–2025. Tenth-grade social studies stood out at 75% proficient versus 48.25% statewide, and 6th-grade ELA reached 62.5% versus 54.95%. Fourth- and 8th-grade science and social studies were above state in 2024–2025 as well.
Challenges show up in college-readiness and middle-school measures. ACT results were far below state levels in ELA (13.64% vs. 48.47%), mathematics (9.09% vs. 42.93%), and science (18.18% vs. 43.2%). In 2025–2026, 8th grade trailed the state in every subject — ELA 28.57%, math 23.81%, science 38.1%, and social studies 47.62% — and science slipped from above state in 2024–2025 to below state in 2025–2026 at both grades tested. With only 252 students, individual grade cohorts are small, so year-to-year swings, such as 10th-grade social studies moving from 23.81% to 75%, are best read as suggestive rather than definitive trends.
