Adult learning staff play a key role in making lifelong learning a reality. It is they who facilitate learners to develop knowledge, skills and attributes. At the European level there is a lack of information about various aspects of the profession, such as who they are, how they are recruited, what their specific roles and tasks are, what competences and qualifications they are expected or required to possess, what their employment status is, how their professional development is organised, how they are assessed, and how attractive their profession is. This article is meant to bridge this gap and describes the variety of contexts in which adult learning staff are working. Furthermore, it seeks to reveal the factors that promote or affect the quality of the work provided by these practitioners and will address a number of issues that should be on the agenda of policy makers. This article is based on the outcomes of a study that have been carried out by an international research group in the period 2007-2008, under guidance of Research voor Beleid and PLATO University Leiden under contract of the European Commission (DG Education and Culture).
