Dave and Amy Carson are residents of Glenburn, Maine, and have been since they were married 22 years ago. Dave and Amy have sent their daughter, Olivia, now a sophomore, to Bangor Christian Schools—which serves kids from K-12 grades—for her entire school career. The Town of Glenburn is prohibited from paying for Olivia’s tuition 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.
