SchoolDigger Rank ?

of 130 South Dakota High Schools

Better than 11% of South Dakota high schools

Summary

Plankinton High School - 01 serves 86 students in grades 9–12 in the community of Plankinton, South Dakota. Its latest 11th-grade ACT results show a mixed picture: the school’s 2025–26 graduation rate was 96%, compared with 88% statewide, but its dropout rate was 9%, versus 2% statewide. The clearest academic concern is mathematics: 9% of 11th graders were proficient, 25 points below the state and 37 points below nearby Mount Vernon High School- 01.

English language arts has been a relative strength, while math and science have lagged. In 2024–25, ELA proficiency was 76%, 12 points above the state; math was 14%, 22 points below, and science was 38%, 11 points below. On the 2025–26 ACT, however, the school was below the state in all three subjects, with science closest (41%, 4 points below) and math furthest behind (9%, 25 points below). Mount Vernon had stronger 2025–26 ACT results in each subject, while Plankinton’s results matched those reported by the Plankinton School District 01-1. The graduation rate is encouraging, but the dropout rate—7 points above the state and 2 points above the district—stands out as a concern.

Smarter Balanced results show math proficiency declining from 21% in 2022–23 to 14% in 2024–25, while science fell from 47% to 38%; ELA rose from 74% to 76%.
