The ineffectiveness of a quality accreditation mechanism can be attributed to the inability of the accreditation status to provide consumers with information they do not already possess. I present a structural model of demand allowing consumers to infer quality from both accreditation status and firm reputation. I then estimate this model to assess the effectiveness and the impact of the national accreditation system for childcare centers on consumer welfare. My results suggest that disregarding the endogeneity of firms' accreditation choices significantly underestimates the effectiveness of the accreditation system. However, on average consumers do not gain much information beyond what they have inferred from a firm's reputation. The estimates of structural parameters are then used to quantify the value of this information to consumers.
