[Principles of medical expert testimony regarding adolescents' capacity for practical vocational training and work].

The presented approach to adolescents' vocational guidance is based on the ILO principle that work should conform to psychophysical conditions of the worker which should be evaluated before the beginning of work. In the paper the main health problems influencing the work capability have been discussed. It is suggested that the student, his parents and tutor should be informed about his health impairments, the degree of disability and therapeutic possibilities. The psychophysical features characteristic of the adolescence justify the health protection against occupational exposure to harmful agents as well as the activities, for health education and health promotion at school.
