Summary:
Ipswich Public School District 22-6 has one high school, Ipswich High School - 01, serving grades 9–12 with 103 students. The school’s 11th-grade results were above South Dakota’s reported results in five of six subject comparisons: its largest advantages were 33 points in Smarter Balanced ELA and 26 points in Smarter Balanced mathematics. The clearest takeaway is that Ipswich performed above the state in most reported subjects, with mathematics a consistent strength.
There are no other high schools in this group, so Ipswich is the only school at the top or bottom; parents can compare its results with the state instead. In 2024–2025 Smarter Balanced tests, Ipswich scored 97% in ELA versus 64% statewide, 63% in mathematics versus 36%, and 72% in science versus 49%. In the 2025–2026 SD ACT, it scored 63% in ELA versus 48% statewide and 56% in mathematics versus 34%. Science was the exception: 44% at Ipswich compared with 45% statewide, a 1-point gap below the state. Graduation was 97% versus 88% statewide, while dropout was 0% versus 2%.
SchoolDigger’s ranking rose from 27 of 141 schools, in the 81st percentile with four stars, in 2023–2024 to 4 of 166, in the 98th percentile with five stars, in 2024–2025; it then stood at 28 of 130, in the 78th percentile with four stars, in 2025–2026. The results cannot establish a year-to-year score trend because the reported assessments and years differ. As context, the school’s 2024–2025 free/reduced lunch eligible measure was 16%, and its student-teacher ratio was 14.2:1; these figures describe the school but do not show how it compares with peer schools.
