It is the look at the that leads us to questioning and the answers guide us to updating and the production of knowledge. There is always, in the debates of social work professionals, the question of the search for an intervention project that gives a new meaning to the profession in order to respond, not only theoretically coherent but also efficiently, to the demands placed upon them. The purpose of this chapter is to highlight the importance of critical thinking in the training of social workers. The research is based on an exploratory study carried out with recently graduated university students, whose results point to the benefits of this soft skill in the ability to analyze, understand interactions, detect inconsistencies, systematic problemsolving, reflect on beliefs and values, and reintegrate information as a whole.2 social worker is a kind of a good Samaritan, and this is only one of the challenges students are going to face.Over time, reality is altered and new conceptions are incorporated into the way of living, learning, acting, interacting, and thinking. The new resources that are constantly added to the already existing ones have or should have the purpose of better serving the individual and society in general. Dealing with the new and complex situations of the contemporary world requires more and more expertise in ways of thinking and acting and relating. Faced with this reality of constant transformations, how can we find autonomy to decide on what is relevant, important, pertinent, and ethical? Critical thinking fits into this question, when it serves as a filter to select what should be harnessed or discarded in this actual avalanche of instantaneous information.Reflective analysis on the theoretical foundations and intervention models allows social workers to re-equate the directionality of professional action in the context of critical thinking that frames objectivity and questions the reality where it is intervened, as well as the meaning of this intervention in its micro, meso, and macro levels from local to global and from global to local, an exercise that social works constantly need.As Granja says: Knowing in Social Work means understanding the social problems as total social phenomena that arise from the operation of the structures and social relations, without denying the particularity of the individual processes and act with a mission to prevent and repair the structural inefficiencies that prevent the poorest from accessing indispensable resources for building themselves as full citizens [1].Knowledge about the transformation of social reality requires an investment that results from a reflexive activity involving professionals, in a link between theoretical knowledge and practice, through an interdisciplinary approach that requires a theoretical synthesis built with other areas of social sciences, namely psychology, sociology, anthropology and economics, law, public and social policies, among others, which aims to "change the systems of opportunities, promote social relations dynami...
