This text will answer two questions: What are the characteristics of knowledge applied and produced within the framework of social pedagogy? And, how are theory and practice articulated in the production and application of social pedagogical knowledge? To this end, the article first presents some of the different types of knowledge existing in the framework of the social sciences and the characteristics that define them. Following that, an analysis is provided of how theory and practice are related to one another in the application and creation of (social) pedagogical knowledge, and then a proposal is made to define the three levels in this process, which we have called: (I) Research; (2) Integration; and (3) Relationship. Next section analyses how, when and where said social pedagogical knowledge is produced and applied at each of these three levels, and by whom and, it ends with some conclusions.
