In my paper I would like to focus on comparing of two groups of siblings in a different sibling positiron and their presisposition for the choice of the occupation and point out the qualities that an individual carries from the childhood and which can influence the choice of their future occupation. I want to make out and compare the changes in this theory in the course of a decade. According to the statistics I have assumed that the firs-bor will choose still occupations demanding accuracy, high conce thein perfectionism and thein will to achieve success. On the contrary, the youngest ones are supposed to be free thinkers and chaose flexible and independent occupations. Both the hypothes have proved true. For collection the date this thesis I use questionnaire. It was filled up with randon representatives with different age. I made a research by comparing the representatives of the oldest and the youngest siblings and partially also middle ones.
