In highly structured VET-systems like the German dual system, the accreditation of informal learning is unusual because it endangers the VET-system. This is because the legal rights connected with an apprenticeship exam are devalued if the same qualification could be achieved without that examination. The social partners seek to protect those who have gained their qualifications through an apprenticeship by ensuring that the accreditation of informal learning is reduced to a minimum in order. The German “Externenprüfung” (External Examination) operates according to the normal rules for apprentices. The accreditation of informal learning is practised more in more in professional fields related to training for leisure time activities like horse riding, tennis, golf or sailing. In these sectors, the accreditation of informal learning is the common way of qualifying for the profession. The difference between the two types of qualifications is that the first is accredited a sports association while the apprenticeship exam is assessed through a state-run examination board.
