As in many school districts around the world, prospective high-school students in Ghana are assigned through a centralized system. Using administrative data on applications, we report that virtually all students adopt a weakly dominated strategy, and matching outcomes show that more than 12\% of students end up unassigned, while almost a third of schools have at least one vacancy. To rationalize choices in this setting, we build and estimate a model where students engage in a costly search process to acquire information over school characteristics. The key insight of the model is that schooling decisions are exerted without the full examination of all available options, which may lead to sub-optimal choices. Using administrative data on choices and a survey on beliefs, we document a substantial welfare loss: distance traveled to schools could be divided by 4. Counterfactual simulations show that if a planner were to restrict choices and assign the highest test score student to the most selective school, welfare would increase by 80\%. We propose a mechanism design reform and show that collecting preferences over a limited number of school attributes rather than actual choices would recover most of the lost welfare.
