The development and promotion of competence is one of the most important theoretical and practical fields in initial and continuing vocational education and training. This book presents many detailed approaches and extensive experience derived from the model experiment series "Flexibility for Initial and Continuing Vocational Education and Training". 38 authors from the field of initial and continuing vocational education and training (practice, research and politics) present models of competence development, competence management and competence assessment that were developed, tested and researched within the framework of model experiments. Key terms such as change competence in fields of experience, ability to shape occupational biography, core competence of training specialists or validation and recognition of informally acquired competencies are covered in occupational contexts. The relationship to the German and European training framework as well as to ECVET and DECVET is also addressed. The book is further enriched by reports from Austria, the Netherlands, Denmark and Sweden. It thus offers not only stimulus for debate on educational science and policy, but suggestions for training of university students and inhouse educational staff as well.
