Discourse on professionalisation and professionalism is a longstanding focus in adult education practice and research. Drawing on the theoretical framework of Freidson (2001) and Noordegraaf (2007, 2015), this qualitative research combined an explorative method and an in-depth analysis (Nutt Williams & Hill, 2012; Williams & Morrow, 2009). It focussed on the comparison of adult education programmes at the Master's level in three countries (document analysis), and the critical reflection on logics of action three adult educators of the referred countries themselves use to describe their work (semi-structured interviews). Thematic content analysis was used to examine data concerning academic professionalisation and professionalism in adult education. Findings showed that the extent of promoting professionalisation appeared differently in each country, depending on the social and historical contexts and the interplay among several factors within which higher education institutions offering programs on adult education are settled. In addition, the practice of adult educators expressed by themselves involved several logics of action. This study highlights the presence of hybrid professionalism in adult education.
