Aim: The goal of the presented research is to describe the dependency between the motivation for achievement and the perception of family in emerging adults. Methods: The Family Relations Questionnaire – 1; Family Perception (by M. Plopa and P. Połomski) and The Achievement Motivation Inventory – LMI (by H. Schuler, G.C. Thornton, A. Frintrup and M. Prochaski) were used in the research. The sample included 100 high school students aged from 19 to 19, 54 from cities and 46 from the country. Results: The results proved that the achievement motivation level is connected to the perception of family. Moreover, the use of the Achievement Motivation Inventory allowed the tested emerging adults to expand their knowledge of values and personal choices. It is presumed that their personal values may grow more independent from both the environment and the effects of upbringing in the future. Conclusions: Achievement motivation pertains both to attitudes and values shaped in the home and at school. It constitutes defining one’s goals that derive from one’s personal interests, in an autonomous manner. It manifests itself in acting in a socially defined way and is a standard of our thoughts, attitudes and behaviors, which describe who we are and how we treat other people. It is a criterion of our evaluations, decisions and choices. The dependencies obtained in the study indicate young people’s need for independence. In addition, statistically significant, directly proportional correlations of weak strength between the degree of satisfaction with family communication and the general motivation for achievement and its following dimensions: self-control, perseverance, internalization, performance satisfaction, compensatory effort, goal orientation, enthusiasm for learning, tendencies to domination, faith in success, preference for difficult tasks, courage in predicting the effects of actions and flexibility, allow the supposition that the researched emerging adults strive to achieve a satisfying sense of identity and purpose – to take on the tasks posed by the school and early adulthood.
