Summary:
Niagara School District contains a single high school: Niagara High, a combined middle and high school serving grades 7–12 with 184 students at 700 Jefferson Ave in Niagara, WI. Because it is the only high school in the district, there is no cross-school comparison to make — everything below describes Niagara High. The district itself ranks 245 of 432 Wisconsin schools, at the 43rd percentile with 2 stars.
Niagara High's clearest strength is its trajectory. Its school rank climbed from 316 of 431 (27th percentile, 1 star) in 2023–2024 to 279 of 431 in 2024–2025 and 213 of 533 (60th percentile, 3 stars) in 2025–2026 — a 103-position gain against a larger pool of schools. Completion measures are also strong: a 94.4% graduation rate versus Wisconsin's 92.0%, a 0.5% dropout rate versus 1.1%, and chronic absenteeism of 11.3% versus the state's 17.3%, though above the district's 9.0%. In 2025–2026, 10th-grade ACT results are above state in English Language Arts (60.61% vs. 48.47%) and Math (51.52% vs. 42.93%), and 8th-grade proficiency is above state in ELA (63.64%), Social Studies (68.18%) and Science (59.09%).
Gaps remain. Seventh-grade ELA (36.11% vs. 55.33%) and Math (44.44% vs. 55.67%) are below state, as is 8th-grade Math (40.91% vs. 53.67%) and 10th-grade ACT Science (33.33% vs. 43.20%). Tenth-grade Social Studies is near parity at 48.15% vs. 48.25%. Across the nine tests reported in both years, Niagara High's average proficiency rose from roughly 49.9% to 52.5% while the state moved from about 52.0% to 52.8%, narrowing the gap. With 184 students, a student-teacher ratio of 12, per-student spending of $15,717 and 42.39% eligible for free/reduced lunch, year-to-year swings should be read with caution.
