This article presents a study on a Primary and Secondary Education teacher training network from Catalonia for the implementation of the Reading in pairs program. The goal is to describe, analyse, and assess the training model’s characteristics in relation to the learning promoted among participants, as well as the possibilities of actually incorporating educational innovation in the schools. The results suggest that this formative ecosystem permits a degree of learning and understanding of the program and its conceptual foundations that is relevant to the ability to implement it creatively and to adapt it to each school so that its sustainability is guaranteed.
