This paper presents a large-scale field experiment assessing the impact of an intervention providing evidence -based information about costs and returns to higher education. Treatment impacts are evaluated through university enrolment, choice of field of study, and performance either at university or in the labour market. Thanks to the large sample size, treatment effects can also be assessed for subgroups (by gender and parental education).We find that treated females from high-educated families chose more economically rewarding fields of study, while treated males from low-educated families were more likely to enter the labour market. Although not necessarily in line with policy goals, choices induced by additional information were not detrimental to students' opportunities, as treated students displayed a similar academic performance and higher employment rates.
