Summary:
Zip code 48880 in Michigan is home to two high schools serving very different student populations: St Louis High School, a traditional public school for grades 9-12 within the St. Louis Public Schools district, and St Louis Correctional Facility, a small school of just 13 students operated by the Michigan Department of Corrections.
For parents, the clear focus is St Louis High School, which enrolls 244 students. The school presents a mixed picture. On one hand, its graduation rate is exceptional at 98% (state average is 84%), and its dropout rate is just 2% compared to 7.1% statewide. This suggests a strong commitment to keeping students on track to earn a diploma. However, academic performance on standardized tests is a concern, especially in mathematics. Only 11.5% of 11th graders scored proficient on the SAT math section, far below the state’s 26.5%. Reading and writing scores are also below average (45.9% vs. 52.1%), while science and social studies proficiency rates are closer to state norms. The school’s state ranking has dropped dramatically from 78th in Michigan (2023-2024) to 464th (2025-2026), reflecting a sharp one-year decline in test scores across nearly all subjects. For example, science proficiency fell from 56.5% to 31.1% in just one year.
Nearly 60% of students at St Louis High School are economically disadvantaged, and chronic absenteeism (27.8%) matches the state average. The school spends a relatively high $15,423 per student, yet math remains a persistent weakness across all grade levels. The St Louis Correctional Facility school offers no comparable academic data, so it cannot be evaluated against the public high school. Overall, parents should weigh the school’s outstanding graduation success against its below-average test scores and recent academic decline when making decisions.
