While in the United States, career counselling and school counselling are the most important fields of activities of the G.C.D.F., labour market integration has become an important issue in Europe. European activities and projects like E.Q.U.A.L., E.S.F. etc. have often a focus on labour market integration. In many European countries, a real, integration industry' came into existence during the last decades. However, there is still a great demand for qualified staff. Many agents who are active in the field of career services or labour market integration do not have an academic education or vocational training but are experienced practitioners with a lot of evidence-based skills and network resources. In this paper, five areas of activities are identified where these practitioners could profit from a G.C.D.F. training.
