How can professional competence be measured? How can competences be detected early in vocational training so that European professional qualifications can be made comparable? The book examines the structure and scope of competences relating to competence requirements of business management. The author develops tools for measuring professional competences which allow for the systematic recording of job activities and argumentations. This is based on a business domain model which can be used for the development of instruments for measuring competences as well as for designing training programs. After an introduction to probabilistic test theory, the book presents psychometric models and procedures of vocational competence measurements in full time school and dual educational systems.weiterlesen
