From being the the Department of Education's favourite to having no space to teach. Three years ago, the Department of Education announced that it would double the number of all-through schools in Catalonia, a formula that brings together infant, primary and secondary education – as many chartered schools do – with the aim of trying to reduce segregation and absenteeism in secondary education. Most of the new centers were created by adding the first year of secondary education to a primary school, a measure that, as well as the pedagogical reasons, was also "of budgetary efficiency", since it is cheaper to have more groups in a school that already exists than to build one from scratch. Despite the fact that the Catalan Education minister at the time, Josep Bargalló, guaranteed that no prefabricated modules would be used, three years later secondary school students in some centres continue to be housed in temporary modules in the palyground.
