Rapid City, S.D. – South Dakota’s graduating seniors continued a streak of academic achievement this year, with the class of 2026 posting an average ACT composite score of 21.1. That figure sits well above the national average of 19.2, marking the sixth straight year the state has outperformed the countrywide benchmark.
The South Dakota Department of Education reported that 56% of the state’s 2026 high‑school graduates took the ACT. Among those test‑takers, three students earned a perfect composite score of 36, highlighting the presence of top‑tier academic talent within the state.
Comparing the latest results with the previous year shows a modest increase for South Dakota. The average rose from 21.0 in 2025 to 21.1 in 2026, while the national average slipped from 19.4 to 19.2 over the same period. The state has maintained its position above the national average every year since 2021.
Methodology note
The department noted a key difference in this year’s reporting: the 2026 composite scores may include only the English, math, and reading sections of the ACT. In prior years, the science section was also part of the composite calculation. This change could affect direct year‑over‑year comparisons, but the overall trend of strong performance remains clear.
The ACT remains a widely used tool for college admissions, and its scores also provide insight into college and career readiness. Schools often use these results for course placement decisions and to help determine eligibility for financial assistance.
Looking ahead, the Department of Education plans to release its full accountability report card later this fall. That report will incorporate results from the ACT administered to South Dakota public‑school juniors in the spring of 2026, offering a more comprehensive view of student achievement across the state. Those junior scores are not included in the figures released on Wednesday.
State education officials have praised the consistent outperformance, emphasizing the importance of maintaining high academic standards and supporting students as they prepare for post‑secondary success. The continued upward trajectory underscores the effectiveness of local schools and the dedication of teachers, families, and communities throughout South Dakota.
