In other occupations—nuclear power reactor operators, for example—trainees take formal courses, often provided at the jobsite, to prepare for the required licensing exams. In addition, the category includes occupations in which workers typically need to possess a natural ability or talent—musicians and singers, athletes, dancers, photographers, and actors, among others—and that ability or talent must be cultivated over several years, sometimes in a nonwork setting.
