High Schools in Mount Vernon School District 17-3

High schools in Mount Vernon School District 17-3 are represented by one school, Mount Vernon High School- 01, serving grades 9–12 with 87 students. Its latest reported graduation rate was 91%, equal to the district rate and above South Dakota’s 88%, while its dropout rate was 5%, higher than the district’s 4% and the state’s 2%. The clearest academic finding is that the school was above the state in math and science, but below it in ELA, in the latest reported results.

There is no other listed high school to rank above or below it within the district, so the useful comparisons are with South Dakota. In 2025–2026, Mount Vernon High School- 01 was 12 percentage points above the state in math and 9 points above in science, but 2 points below in ELA. In 2024–2025, it was above the state in all three subjects: by 4 points in ELA, 14 in math, and 19 in science. Its three-subject average was 12 points above the state average that year and 6 points above in 2025–2026, though these results do not establish a year-to-year trend because the assessment changed.

SchoolDigger’s ranking was lower in its latest listed year than in the two preceding years: the school ranked 40th of 130 schools, at the 69th percentile, in 2025–2026, compared with 23rd of 166 (86th percentile) in 2024–2025 and 24th of 141 (83rd percentile) in 2023–2024. The school’s student–teacher ratio was 13.1:1 in 2024–2025, and 32% of students were free/reduced lunch eligible that year. These figures offer context, but the single-school list cannot show how the school compares with similar schools.
