Adolescence is a phase in life cycle in which the individual goes through a series of physical and psychological transformations. In this period there is the consolidation of identity and the youngster faces a range of choices that will define his future, including the professional choice. Many factors exert influence in this choice and the adolescent will make it based on his social, cultural and psychological context. The decision for a professional career is part of a continuous process that starts early on, with a great participation of family life history. This research had the goal to analyze family influence in professional choice, observing aspects of generational transmission. Two families (composed by father, mother, and one adolescent) were interviewed. The adolescents were students in the third grade in middle school; families lived in the city of Niterói, in Rio de Janeiro, and were from middle-class. Interviews were recorded, transcribed, and their content was later analyzed. From interviews’ content three categories of analysis emerged, which configured fundamental themes in participants’ reports. It was observed that the family exerts a great influence in the moment of professional choice, placing expectations, making demands in direct and indirect ways, and transmitting values about certain occupations. It was concluded that professional choice is not made by chance, but is related to professions for which values are transmitted by prior generations and to the roles that each person should play in the family dynamics.
