When choosing a profession or occupation, the interests, the abilities, the inclination, innate propensities and, last but not least, health must be considered. Being fit for the job prevents dropouts in vocational education and from giving up the occupation, and avoids cases of employment rehabilitation. Before the decision on a vocational training is taken, a medical examination and consultation of an occupational and sociomedical expert should be mandatory. The results of a study on the reasons of the vocational education dropouts or for giving up the occupation are presented and conclusions for improvement are discussed.
