With some exceptions, most Mercer Island elementary school students attend the school closest to their home as defined by the Mercer Island School District’s boundary map.
There is only one middle school and one high school on Mercer Island, so starting in sixth grade, all Mercer Island public school students will attend the same school as other students in their grade.
If you are considering purchasing a home close to a boundary and have a desired elementary school in mind, you should confirm the elementary school assignment by visiting the school district’s Transportation Search page and by contacting the district’s transportation director.
