In Sweden there are several different professions that work within the welfare sector. Two of these are social pedagogues and socionoms. This article examines the similarities and differences between these professional fields by exploring four areas in more detail: education, the history of ideas and theory, research and practice. The results show that there are not only many differences but also some similarities. In practical work, social pedagogues and socionoms often work side by side and perform similar tasks. They are located in the same areas and often use the same methods. When it comes to the differences in educational history and current educations, they are large although they can also be found in, for example, the history of ideas. Furthermore, research in the various areas differs. In social pedagogy the interest has to a greater extent been focused on an understanding of the discipline through studies of the history of ideas, while in social work today one often focuses on studies of professional methods. Today’s challenges in the welfare sector require new knowledge, ways of thinking and understanding. Here, social pedagogy with its philosophical roots and humanistic values can play an important role.
