Summary

Tri-Valley High School - 01 serves 297 students in grades 9–12 in Colton, South Dakota. Its 2025–2026 graduation rate was strong at 99%, compared with 88% statewide, but the clearest concern is math: only 20% of students were proficient, 14 percentage points below the state and 9 points below the nearby-school average.

Science is the school’s strongest current subject compared with nearby schools, its district and the state: 47% were proficient, versus 45% statewide, 46% in the Tri-Valley School District 49-6 and 42% across comparable nearby schools. ELA was closer to the middle: 45% proficient, about 1 point above the district and nearby-school average, but 3 points below the state. The graduation result also stands out locally: Tri-Valley’s 99% rate was the highest among five nearby regular high schools with reported results.

Graduation improved 7 percentage points from 2021–2022 to 2025–2026, while SchoolDigger’s statewide percentile fell from 86 to 31 over that period. In 2025–2026, SchoolDigger ranked the school 90th of 130 statewide, at the 31st percentile with two stars. Contextual measures include a 15.2:1 student-teacher ratio in 2024–2025, below the 16.5:1 nearby-school average, and 15% free/reduced lunch eligible in 2024–2025, below the nearby average of 19%. SchoolDigger’s 2024–2025 subgroup rankings indicate stronger results in serving Foster Care Students, at the 91st percentile compared with the school’s overall 47th, and weaker results for Military Connected Students, at the 11th percentile; group counts were not supplied.
