Summary:
ZIP code 57101 has one listed public high school, Jefferson High School - 67, serving grades 9–12 in the Sioux Falls School District 49-5; it enrolls 1,888 students. Because it is the only school in the ZIP-code list, there are no local school-to-school comparisons. The clearest overall finding is that Jefferson’s results vary by assessment: it was well above the state in Smarter Balanced English language arts and science, but below the state in all three reported ACT subjects.
Jefferson’s strongest comparisons with the state were in 2024–2025 Smarter Balanced results: 67% were proficient in English language arts, 16 percentage points above the state, and 53% in science, 10 points above. Math was the exception, at 42%, 2 points below the state. On the 2025–2026 grade-11 SD ACT, the school was below state results in every subject: English language arts was 38%, 10 points below; math was 31%, 3 points below; and science was 40%, 5 points below. Math is the most consistent relative weakness because it was below the state on both assessments. There is no top or bottom school within this ZIP-code list.
SchoolDigger’s ranking history rose from the 63rd percentile and 3 stars in 2023–2024 to the 73rd percentile and 4 stars in 2024–2025, then fell to the 27th percentile and 1 star in 2025–2026—a 46-point percentile drop from the prior year. The graduation rate was 87.9%, nearly the state’s 87.8%, while the dropout rate was 3% versus 2% statewide. In 2024–2025, the student–teacher ratio was 16.1 and 49% of students were free/reduced lunch eligible; these are context, not explanations for results. The test snapshots cover different years and grade spans, so they do not show a direct test-score trend.
