Although the literature on school choice rationalities is extensive, different authors interpret the processes of school choice for poor families in different ways. Positions vary between those that consider that poor families have the same capacity to choose as middle class families and those that value structural factors as constraints for choice. The objective of this article is to identify different school choice rationalities of low income families in the context of a highly marketized education system such as Chile. Beyond the restrictions of a different nature that poor families face, this social group mostly expresses high levels of reflexivity and complex sets of preferences when it comes to choosing schools for their children. This article tries to overcome the dualistic division that prevails in school choice literature between choice as an outcome of utility maximization for all, and choice as a denial for deprived groups.
