Summary:
Groton Area School District 06-6 has one high school, Groton Area High School - 01, serving grades 9–12 with 168 students. The school’s 11th-grade results are above South Dakota’s in every reported subject in both years, its clearest overall strength.
Groton Area High School - 01 is the sole school in the list, so there is no meaningful local top or bottom to compare. In 2025–2026, 67% of students were proficient in English language arts, 53% in mathematics and 70% in science—18, 19 and 25 percentage points above state results, respectively. In 2024–2025, proficiency was 86% in English language arts, 43% in mathematics and 59% in science, exceeding state results by 23, 7 and 10 points. Graduation was 100% in 2025–2026, compared with 88% statewide; the dropout rate was 0%, versus 2% statewide.
SchoolDigger’s school ranking improved from 28 of 141 in 2023–2024 to 22 of 166 in 2024–2025 and 5 of 130 in 2025–2026; its district record is 6 of 126 with five stars. The subject with the largest state advantage varied: English language arts in 2024–2025 and science in 2025–2026, while mathematics had the smallest margin in both years. These results are not a simple year-to-year trend, and no school-to-school comparison is possible because the area has only one high school. Context figures include a student–teacher ratio of 12.5 and 11.9% free/reduced lunch eligible in 2024–2025.
