Summary
South High is a public high school in Sheboygan, Wisconsin, serving grades 9–12 with 1,075 students as part of the Sheboygan Area School District. It ranks 421 of 533 Wisconsin high schools in 2025–2026 (21st percentile, 1 star), up from the 5th percentile in 2021–2022 but still in the bottom quartile. About 66.7% of students qualified for free or reduced lunch in 2024–2025, a sharp rise from 49.6% the year before. Per-student spending is $14,246, and the student–teacher ratio is 14.9.
Test scores are the school's clearest weak spot. In 2025–2026, 10th-grade proficiency was 37.69% in social studies, 35.68% in English language arts, 27.31% in math, and 25.11% in science — below the district and state in every subject, with science 18.09 percentage points under the state and math 15.62 points under. All four subjects slipped from 2024–2025, though each is higher than in 2022–2023. North High, the district's other large high school, outperforms South in every subject (47.47% math, 46.98% ELA) and ranks 269 of 533 with 2 stars, while the much smaller Etude High ranks 67 of 533 with 4 stars.
Completion is a relative strength: South's 2024–2025 graduation rate was 91.3%, above the district's 88.1% and close to the state's 92.0%, and its 0.9% dropout rate beats both — and beats North High (89.9%) and Central High (70.6%). Attendance is the biggest concern: 34.5% of students were chronically absent, roughly double the state rate and far above Kohler High (3.7%) or Oostburg High (7.0%). Subgroup results are uneven — English learner and special education students ranked at the 57th percentile, while low-income students were at the 19th. Nearby suburban schools post far higher proficiency, such as Oostburg's 72.41% ELA, despite similar or only somewhat higher spending.
