Summary:
Marion, South Dakota, has three schools serving 208 students from prekindergarten through grade 12: Marion Elementary - 02, Marion Middle School - 03 and Marion High School - 01. The clearest shared pattern is stronger math than English language arts (ELA): elementary and middle math averaged 53% proficient in 2025–26, 9 points above the state average, while their ELA averaged 41%, 8 points below the state. The high school’s 11th-grade math was 8 points above the state, while its ELA was 15 points below. Overall, math is the strongest common academic result, and ELA is the clearest area of concern.
Marion Middle School - 03 had the highest all-grades math result, at 53%, just above the elementary school’s 53%; both exceeded the state’s 44% by 9 points. The elementary school’s fourth-grade math was a particular bright spot at 73%, 24 points above the state, while fifth-grade math was 31%, 11 points below. Middle-school ELA varied by grade: eighth grade was 6 points above the state, but sixth grade was 21 points below. At the high school, graduation was 100%, compared with 88% statewide, and dropout was 2%, below the state’s 2%. SchoolDigger ranks the elementary school 144th of 203 (29th percentile, 1 star), the middle school 91st of 151 (40th percentile, 2 stars), and the high school 72nd of 130 (45th percentile, 2 stars).
Recent results moved in different directions: the elementary and middle schools’ average math proficiency rose 8 points from 2024–25 to 2025–26, while their average ELA fell 8 points. Science is a notable exception to the math strength: fifth-grade elementary science dropped 29 points year over year, and eighth-grade middle science fell 47 points. Context differs across schools: student-teacher ratios were 9.4 at the elementary school, 11.7 at the middle school and 8.9 at the high school; free/reduced lunch eligible shares in 2024–25 were 38%, 52% and 48%, respectively. These context measures do not explain achievement differences. The high school’s test changed between years, and school-wide results cover different grade spans, so some comparisons are not like-for-like.
