We investigate the labor market payoffs to higher education in Brazil by leveraging the unintended effects of a policy targeting fraud in a national high-stakes high school exit exam. To prevent cheating, students are assigned one of four different examination books. While the only difference across groups is the order in which the questions are presented, some students are penalized since they randomly get easier questions later in the test. We observe striking differences in scores across examination groups, and subsequent differences in the rates of entrance to higher education.
