In many regions of the world, professionalisation in adult and continuing education is brought into the focus of educational policy and research. Various fields of practice are looking for scientifical and political support in raising the level of professionalism. While there are no simple lessons to be learned from other countries, a closer analysis of international experience may reveal common and diverging interests. It may also provide worthwhile insights into opportunities and risks surrounding professionalisation. This edited volume is intended to further stimulate international exchange, cross-country approaches and comparative research in this field. It includes contributions to the theoretical debate and to the development of (comparative) research as well as reports on research findings and development activities concerning the professionalisation of adult educators.
