Summary:
Zip code 57384 includes three schools in Wolsey, South Dakota: Wolsey Wessington Elementary - 02 (PK–5, 145 students), Wolsey Wessington Middle School - 03 (grades 6–8, 75 students), and Wolsey Wessington High School - 01 (grades 9–12, 96 students). In 2025–2026, the high school’s 11th-grade ACT results were above state rates in ELA and math, while the elementary and middle schools’ all-grades results were below state averages in both subjects. The most important area-wide finding is that math is the largest reported proficiency gap in the elementary and middle grades: their average was 24%, compared with 44% statewide, a 20-point shortfall; in ELA, the average was 37% versus 49%, a 12-point shortfall.
The high school stands out on its reported measures: 11th-grade ELA proficiency was 57% versus 48% statewide, and math was 43% versus 34%—gaps of 8 and 9 points. Its graduation rate was 96%, 8 points above the state’s 88%. By contrast, the middle school’s grade-6 results were a low point: ELA was 19% versus 48% statewide, and math was 10% versus 42%, gaps of 29 and 32 points. Within the lower schools’ all-grades results, elementary led in ELA (41% versus middle’s 33%), while middle edged ahead in math (25% versus elementary’s 23%). SchoolDigger ranked the high school 44th of 130 (66th percentile, 3 stars), compared with elementary at 157th of 203 (23rd percentile, 1 star) and middle at 131st of 151 (13th percentile, 1 star).
Recent results show improvement in some areas but not others. From 2024–2025 to 2025–2026, elementary ELA rose 5 points and its gap to the state narrowed; elementary math fell 6 points. Middle math rose 1 point, but ELA fell 3 points. Grade-5 science at elementary rose 21 points to 45%, while grade-8 science at middle fell 16 points to 12%—a notable contrast across different grades. Elementary and middle chronic absenteeism remained below the state rate in 2025–2026: 4% and 8%, versus 20%. Context measures also differ: in 2024–2025, the share eligible for free/reduced lunch was 29% at elementary, 32% at middle, and 41% at high school; student–teacher ratios were 12.7, 13.1, and 11.3, respectively. These figures describe the schools but do not establish what explains their results.
