This article analyses the impact of social class on the process of school choice in Spain from the viewpoint of middle-class families. This practice must be seen in the framework of the new social context generated by the information society. The article begins by briefly describing changes in school choice policies in Spain. For a wider understanding, these changes are related to the broader process of the marketisation of education, which has been taking place in this country for the last 20 years. In the second part of the article, qualitative data are presented on how middle-class parents understand and experience the process of choosing a particular school for their children. In this study, 24 interviews were carried out in the city of Granada (southern Spain). They were fully transcribed and analysed using the methodology suggested by ‘grounded theory’ and Bourdieu's concept of social class. Aspects related to social and cultural capital are added to the traditional social class indicators, which are usually expressed in economic terms. Attention centres on the creation of reconversion strategies for these different forms of capital used by families to obtain positional advantage for their children. This research thus revisits the principles of social reproduction theories from the viewpoint of the ‘winners’, i.e. middle-class families.
