Summary
Simley Senior High is a public high school serving roughly 1,030 students in grades 9–12 in Inver Grove Heights, Minnesota, part of the Inver Grove Heights Schools district. For 2025–2026 it ranks 325th of 473 Minnesota high schools (31st percentile, 2 stars), a significant drop from a decade ago, when it ranked 143rd of 489 (71st percentile, 4 stars). Graduation is a real strength: 89.6%, above the district (87.2%) and state (84.9%). The dropout rate of 4.9%, however, is above the state's 4.2%.
Academics are the main concern. In 2025–2026, 13.7% of students met math proficiency, 32.4% reading, and 25.6% science, compared with state averages of 44.9%, 48.6%, and 25.5%. Math has declined four years in a row (from 25.34% in 2022–23) and now sits below one-third of the state average. Science is the bright spot, essentially matching the state and exceeding the district's 17.2%. Nearby schools show a wide range: Eagan Senior High posts 62% math, 65.6% reading, and 67% science; Two Rivers High School 45.4%, 43.8%, and 32.4%; and South St. Paul High School 17.3%, 38.4%, and 26.6%.
About 48.35% of students qualified for free or reduced-price lunch in 2024–2025 — similar to Two Rivers and South St. Paul — yet Simley's student-teacher ratio of 23.1 is the highest among nearby comprehensive high schools (16.8–19.8). Subgroup results have improved markedly since 2023–2024, with African American students moving from the 7th to the 68th percentile and Asian students from the 44th to the 85th, alongside gains for English learners, special education students, and low-income students. Multi-racial students remain in the 8th percentile.
