Since the early 1960ies, the Aachen Chamber of Skilled Crafts and Trades qualified thousands of people from all over the world. They completed technical training, management training or were trained as consultants. Responsible for these business activities is now QualiTec German Limited. In the last years, most of the training measures were performed in form of "train-the-trainer"- programmes; i.e. that the participants not only develop expert competence in the training course, but also are supported in additional courses to build up pedagogical competence. Thus, in many countries of the world, experts having successfully been trained in Aachen train other people professionally in their profession.
