This year, for the first time in a decade, fewer high-school students admitted to cheating, according to a survey by the Josephson Institute of Ethics. Of students who participated in the poll, 51% said they cheated on an exam in the past year, down from 59% in 2010, and 55% said they lied to a teacher, a drop from 61% in 2010. Officials say the shift is due to a greater focus on character at home and at school.
