• This thesis addresses these three research shortcomings. To determine where learning takes place in VET and the barriers to learning at the workplace that may occur, this thesis is guided by the overarching question, what are barriers to learning and how can they be measured? The following four sub-questions further structure the thesis: 1) What challenges and problems do VET professionals face in their professional development? (Study I) 2) What are the learning conditions and informal and formal learning activities of professional trainers and training managers? (Study II) 3) What are the experienced barriers to learning, and how can they be categorized? (Study II) 4) How can barriers to learning at the workplace be categorized and be measured? (Study III)
