We run a field experiment in which we provide information to students about job opportunities and hourly wages of occupations they are interested in. The experiment takes place within a widely-used career orientation program in the Netherlands, and involves 28,186 pre-vocational secondary education students in 243 schools over two years. The information improves the accuracy of students' beliefs and leads them to change their preferred occupation to one with better labor market prospects. Administrative data that covers up to four years after the experiment shows that students choose (and remain in) post-secondary education programs with better job opportunities and higher hourly wages as a result of the information treatment.
