This article describes a collaborative action research project developed over the course of the 2011/12 academic year in the Faculty of Education at Cordoba University (Spain). The RIECU school-continuing professional development centre for teachers-university learning network is part of this research process. The aim is to create and consolidate a community of practice made up of continuing professional development advisers to teachers, infant education teachers, university students who are training to become infant education teachers and university teaching staff. The most relevant findings, which respond to the questions raised, are: the action research conducted indicates that teamwork between teacher, adviser, researcher and university student is an effective strategy to facilitate the acquisition of professional competences among student teachers; and student-teachers involved in the case study have evolved in their conception and approach to childhood and have had the opportunity to learn by modelling the professional conduct of their mentor teachers.
