Contemporary social work is focused on constructing its scientific identity: its scientific and practical interests, definitions, theories and methodological procedures. Social work is related to many approaches present in socio-humanistic sciences eg. Sociology, social pedagogy, social psychology, cultural anthropology, social policy, as a result of its scientific interests and interdisciplinary. In context of international discourses it is needed to talk about new paradigm of social work as a (sub) discipline, because we have been already experiencing process of disciplinarization, besides some formal barriers. The aim of this paper is exploration of the phenomenon of social work in context of different research and practical processes, which conduct to new paradigm of social work as a (sub) discipline. Discussing formal criteria of disciplinarization shaping a framework for professional and scientific identity of social work - I hope to create more friendly climate for acceptance for its further academization in Poland.
