Kevin is a student at St. Jerome's Catholic School.
He was in Sister Thomasina's class when Bart was enrolled to the school after he was being falsely expelled from Springfield Elementary by Seymour Skinner for the prank, which was really actually caused by Groundskeeper Willie who was the one should have been fired.
Later, when Father Sean asked the class about transubstantiation, Kevin knew the right answer. However, Homer who joined the class too, answered faster than Kevin. Kevin then accused him to cheating, because Homer had an answer written on his arm.
