The aim of the article is to analyse the concept of social exclusion in EU lifelong learning policies: how the concept has evolved from the 1990s in terms of meaning, definitions and closely connected concepts, what are the implications of this evolution, and whether there is coherence between the conceptual evolution and lifelong learning policy. Using a qualitative methodology, this article focuses on policy documents that form the European Union's legal and political framework of reference in the lifelong learning area in the last two and a half decades. A total of 59 documents issued between 1992 and 2017 have been analysed using content analysis. The analysis of the documents has been complemented by 6 semi-structured interviews with EU lifelong learning experts. The results show that the concept is narrowly defined in terms of specific groups at risk of being socially excluded and in terms of employability, thus individualising the problem of exclusion and distracting attention from structural factors.
