The current requirements of the professional training show a change in the process of teaching-learning and the need to have methodological tools in accordance to the 21st century skills. Within the constructivist model of learning, model adopted by the University of Atacama, one of the techniques applied for professional training is the project based approach, mainly for its didactic, applied and experiential characteristic. The results from an analysis of coherence between the formative proposal of the Social Work program from the University of Atacama are shown in this article. Specifically in the professional practice and the Project Based Learning approach which has been developing since 2019. Through a documental and scientific revision, the theoretical-conceptual components which ground a virtuous relation between the processes of professional practices and the project based approach are sought to acknowledge. A tacit coherence which enhances the formative propose of the program, which are the three elements that are overlapped in the development of the professional practice is evident. The elements are: graduate profile, with a transformative counseling; the PBL approach, part of the active methodologies; and the professional practice instance, as a final instance of the program. However, it is necessary for this encounter to be crossed by a clear and permanent intentionality.
