Past studies find that disadvantaged students in the United States are often misinformed about college costs and financial aid opportunities and thus may make sub-optimal decisions regarding college. This information problem may be even more serious in developing countries. We therefore conducted a cluster-randomized controlled trial to examine the effects of providing information on college costs and financial aid to high school students in poor regions of northwest China. We find that information increases the likelihood that students receive some types of financial aid. Information also positively affects the choice to attend college but does not seem to affect more specific college choices.
