TCAT McMinnville’s outstanding student of the year personifies a popular term in higher education. But to call Mary Arthur nontraditional is an understatement and tells only part of her persistent story.Nontraditional means different things to different people. Most of the student body at Tennessee College of Applied Technology-McMinnville is considered nontraditional because they are working adults, many with children.Arthur certainly did not come to TCAT straight from high school.
