The German Qualifications Framework for Lifelong Learning (DQR) offers a concept to evaluate formal and informal competences and to make those comparable within Europe.The contributions to this anthology are based on a series of lectures held at the Helmut-Schmidt University in the year 2010/2011. They deal with the structure and organisation of the DQR from different perspectives and look at implementation options. Further contributions provide stimuli for the development process and the future use of the DQR as a tool of reform.European experiences with the validation of non-formal and informal competences complement the anthology.
