Summary

CarsonvillePort Sanilac High School is a small, rural public school in Carsonville, MI, serving 187 students in grades 6-12 within the Carsonville-Port Sanilac School District.

The most remarkable thing about this school is its perfect graduation record. For four of the past five years, 100% of seniors have graduated, and the dropout rate has been 0% for five straight years. This is especially impressive given that nearly 60-70% of students qualify for free or reduced lunch, and the school consistently ranks in the 86th percentile or higher for supporting students from low-income backgrounds. Academically, the school shines brightest in science and social studies—recent 11th-grade science proficiency was 52.2% versus the state average of 35.2%, and social studies hit 65.2% compared to 43.2% statewide. When compared to nearby schools, CarsonvillePort Sanilac outperforms Peck JrSr High School and Deckerville Community High School in nearly every subject, and it beats Sandusky JuniorSenior High School by a wide margin in science (52.2% vs. 20.3%) and social studies (65.2% vs. 33.8%).

However, there are some challenges to be aware of. Chronic absenteeism affects about one-third of students—higher than the state average—though it's better than the district's overall rate. The school's small size means performance can swing noticeably from year to year as different cohorts move through; recent rankings dropped from the 89th to 74th percentile. Also, while female students currently outperform male students, both groups score above the state median. The school spends about $16,261 per student, and class sizes are relatively large for a small school (20:1 student-teacher ratio). For context, the district's alternative program, the CarsonvillePort Sanilac Learning Center, serves students who need a different setting and has a 50% graduation rate—making the high school's perfect record even more notable. Overall, this is a school that clearly prioritizes making sure every student finishes, with particular strengths in science and supporting economically disadvantaged learners.
