In addition to the intervention of José Manuel Rodríguez, the authors of the book will speak, along with Jaume Martínez-Bonafé, professor at the Faculty of Educational Sciences of the Universitat; Enrique Martín Criado, professor at the Pablo de Olavide University; and Francisco Murillo, professor at the Autonomous University of Madrid.

According to the author, education is a “total social phenomenon” and its knowledge requires specific analysis of its historical, legislative, economic, social, pedagogical and political dimensions. In this direction, it shows, from a legal-constitutional analysis, "the close relationship between the right of families to free choice of educational centre and school segregation in Spanish society". From the other historical, social and pedagogical dimensions, the study finds that the element that contributes most to high segregation is the existence of the double school network financed with public money, since charter schools favour in a decisive way the segregation of students by socio-economic level as well as by national origin or gender.

In the case study of the school map of the city of Valencia, the unequal distribution of the public spending in education, zoning policies, evaluation criteria, the student admission process, the inequality of education opportunities and the process of school segregation are analysed. The proposal includes an action plan with the latter in particular, and actions in fundamental fields of the school process.

The research is the result of an agreement between the Valencia’s City Hall and the Universitat de València that responds to a model of non-commercial collaboration between universities and the public administration that assumes research in public universities as a "common good" and implies an explicit commitment to its democratisation through its transfer to the different social agents involved. The book ends with a sociological analysis of the process of political and legal persecution and media criminalisation of the research itself. An unprecedented process in Spanish sociological research since the end of General Franco's dictatorship.
