Summary:
Zip code 57110 has one high school, Washington High School - 01, serving grades 9–12 with 1,819 students in the Sioux Falls School District 49-5. The school’s strongest result is all-grades English language arts (ELA), while its clearest current concern is 11th-grade ACT science: 39% were proficient, 6 percentage points below the state.
With only one school in the area, there is no school-to-school comparison; the strongest and weakest results are by subject. On 2024–2025 Smarter Balanced tests, Washington’s standout was ELA: 65% proficient, 14 points above the state and 15 above the district. Science was also above the state at 47%, compared with 44%. The weakest result was math at 35%, 8 points below the state’s 43%. On the 2025–2026 11th-grade ACT, ELA and math were essentially level with state results (49% versus 48% in ELA, and 34% versus 34% in math), while science lagged the district as well as the state: 39% versus 46% in the district.
SchoolDigger’s relative standing declined over the reported years: its percentile went from 69 in 2023–2024 to 55 in 2024–2025 and 38 in 2025–2026, while its star rating changed from 3 to 2. This ranking history signals a lower relative position, not a demonstrated decline in test proficiency; the different years’ results do not establish an achievement trend. Completion measures are mixed: the 2025–2026 graduation rate was 90%, about 2 points above both district and state rates, while the 3% dropout rate was about 1 point higher than both. As context, 53% of students were free/reduced lunch eligible in 2024–2025, and the student–teacher ratio was 15.1.
