High Schools in Ortonville Public Schools

Ortonville Public Schools has one high school, Ortonville Secondary, a combined middle/high school serving grades 7–12 with 228 students. Because it is the only high school in the district, it is the sole focus of this analysis. It is also the district's only provider for those grades, so the grade 7–12 results are identical for the school and the district. Note that district all-grade figures include younger students from elsewhere in the district, which makes those numbers a different comparison than a high-school-only view. The student-teacher ratio is 12:1, and 33.77% of students qualify for free or reduced lunch.

Completion outcomes are the standout strength. The graduation rate is 97.1% for 2024–2025, far above the state's 84.9%, and the dropout rate is 0.0% compared with 4.2% statewide. Eleventh-grade math is another bright spot: 44.4% proficient in 2025–2026, 9.1 percentage points above the state's 35.3%, which points to real strength in upper-grade math. The school also hit a high in 2024–2025, ranking 57th of 450 schools with 4 stars (87th percentile).

Academic proficiency is the main concern. In 2025–2026 the school trailed the state in all-grade math (36.9% vs 44.9%), reading (41.9% vs 48.6%), and science (19.8% vs 25.5%), and it declined in all three subjects year over year. Reading showed the sharpest drop, from 50% to 41.9%. Eighth-grade science is the clearest red flag at 5.4% proficient versus 16.7% statewide, an 11.3-point gap. Rank history is also volatile: 193rd of 473 (59th percentile, 3 stars) in 2025–2026, after the 2024–2025 peak, and 193rd of 480 in 2023–2024. The district itself is ranked 135th of 458 (71st percentile, 4 stars), differing from the school's current standing, likely because the two rankings use different grade spans and methods.
