Mackinac Island Public School is a  Pre-K-12 school with an enrollment of 63 students. The elementary classes are divided so two grades are in each class (Prek-K, 1st/2nd, 3rd/4th, 5th/6th). The Middle/High school consists of grades seven through twelve. The average number of students in a class is about six with our largest class with ten and smallest with four.

In order for the students to get to school, they must either walk or ride their bikes in the fall and spring seasons. In the winter, however, snowmobiles are the most common means used to transport students. The average distance to school for most kids is around one mile.

The original structure of the present school building was completed in 1969 and consists of seven classrooms, an office, a kitchen, and a multipurpose room that was used as a gymnasium and dining area. In 1970 a portable classroom (which is still used as a storage building) was purchased and in 1974-75 a group of students constructed an industrial arts building that was attached to the portable. The Mackinac Island Public School has recently undergone additional modifications to the building. In 1992 a library and a science room were added to the main building. In 2000 a full-size gym (below) equipped with locker rooms and a balcony, which is used as a weight room, was added to the northeast end of the school. We also relocated the office, added a computer lab and a classroom, and remodeled many of the original classrooms. These recent additions have more than doubled the size of our school. In 2020 we put in a new gym floor and replaced our roof.
