Understanding parental response to non-test score attributes is crucial to design effective school choice systems. We study an intervention providing parents with hard-to-find information on the school environment while holding information on school performance constant. The provision of this information decreases the outflow to private institutions by 17% and increases enrollment at local state schools, particularly among high-income and high-performing students. This intervention encourages parents to expand their stateschool search without affecting their taste for academic performance, generating increased competition for schools with desirable attributes. These findings imply that simple, low-cost interventions may improve state schools' finances and composition.
