Better than 25% of South Dakota elementary schools

Summary

May Overby Elementary - 09 is a K–5 school in Aberdeen, South Dakota, serving 327 students in the Aberdeen School District 06-1. Its results vary sharply by grade: third grade is a relative strength, while fifth grade is much weaker. In 2025–2026, third-grade proficiency was 54% in English language arts (ELA) and 70% in math, compared with 26% and 28% in fifth grade—the most important finding is that performance drops substantially in the upper elementary grades.

Third grade compares favorably with district and state results, especially in math: May Overby was 9 percentage points above the district and 18 above the state. By contrast, fifth-grade results were well below both. Across all grades, ELA is the clearer weakness: proficiency was 39%, below the district’s 47%, the state’s 49%, and the nearby same-district K–5 average of 50; May Overby also scored below all five peer schools. Math was 44%, equal to the state and just below the district, but 10 points below the nearby-school average; it was higher than one of the five peers. Fifth-grade science was another major concern at 23%, compared with 36% for the district, 41% for the state, and a 37% nearby-school average.

Math has improved over time, rising from 38% in 2022–2023 to 44% in 2025–2026, while ELA slipped from 41% to 39%. SchoolDigger ranks May Overby at the 25th percentile with 1 star for 2025–2026, the lowest standing among its five nearby same-district peers; its percentile was 38 in 2024–2025 and 34 in 2023–2024. The 2024–2025 student-teacher ratio was 11.4, below the peer average of 12.4. Free/reduced lunch eligible students made up 54% of enrollment in 2024–2025, above the peer average of 45%; this is context, not an explanation for scores. SchoolDigger’s group rankings also differ from the overall ranking: in 2024–2025, its Multi-racial Students ranking was at the 70th percentile, compared with the school’s overall 38th percentile. Its Special Education Students ranking fell from the 60th percentile in 2023–2024 to the 25th in 2025–2026, reflecting a notable shift in SchoolDigger’s measure of how well the school serves that group.
