Dave and Amy Carson are residents of Glenburn, Maine. Dave and Amy enrolled their daughter, Olivia, at Bangor Christian Schools—which serves kids from K-12 grades—for her entire school career. The Carsons received no tuition assistance from the Town of Glenburn because Bangor Christian Schools is a religious school, even though Glenburn pays tuition on behalf of its other residents who select non-religious private schools for their children.
