Summary:

ZIP code 57262 has four schools spanning prekindergarten through grade 12: Tiospa Zina Tribal School (K–12, alternative), Westside Elementary - 03 (PK–4), Sisseton Middle School - 02 (grades 5–8), and Sisseton High School - 01 (grades 9–12). The clearest academic concern is at Sisseton Middle: in 2025–2026, its all-grades proficiency was 23 percentage points below the state in ELA, 27 points below in math, and 15 points below in science, with math the largest gap.

Westside has the strongest state-relative profile in the latest results: its all-grades math proficiency was 46%, 2 percentage points above the state’s 44%, although its ELA result was 40%, 9 points below the state. Grade-level results add nuance: Westside math was 3 points below the state in grade 3 and 5 points below in grade 4. Sisseton Middle is furthest below state benchmarks overall, particularly in math (16% versus 44%). Sisseton High’s grade 11 ACT results were also below the state in every subject: 37% in ELA versus 48%, 13% in math versus 34%, and 35% in science versus 45%. Tiospa Zina has no test scores reported here.

Recent trends distinguish Westside from the middle school: from 2024–2025 to 2025–2026, Westside gained 6 percentage points in ELA and 8 in math, while Sisseton Middle fell 7 points in both ELA and math and 5 in science. SchoolDigger’s 2025–2026 statewide ranking percentiles were 27 for Westside, 7 for Sisseton Middle, and 9 for Sisseton High; these are rankings, not test-score percentages. In 2024–2025, free/reduced lunch eligible shares were 74% at Westside, 66% at Sisseton Middle, and 53% at Sisseton High; Tiospa Zina reported all students receive free meals (Community Eligibility) in 2024–2025, a different measure. Student-teacher ratios were 11.6 at Westside, 11.3 at Sisseton Middle, 14.8 at Sisseton High, and 9.5 at Tiospa Zina. These figures offer context, not an explanation for results. Because schools serve different grades, the high school’s latest results use the ACT rather than Smarter Balanced, and Tiospa Zina has no reported test scores, direct achievement comparisons have limits.
