I review the literature on how parents select schools when participating in private choice programs in the United States. I address two sub-questions. First, do parents have the incentives and motivation needed to participate in a schooling market? Second, when selecting a school, what school characteristics do parents consider? I find three general patterns in the literature: (1) There is great consistency in parents' stated preferences of school characteristics across choice programs; (2) Parents value academic quality, but it is not always their most prized school feature; (3) Parents make trade-offs among their preferences when selecting a school.
