Seventh and eighth grade students of primary school are experiencing many changes and soon they will face the biggest decision so far, the decision about what secondary school to choose. The goal of this research was to examine the relationship between fear of failure and emotional competence, emotional stability, fundamental beliefs about myself and support of people close to person. Moreover, we were interested whether students differ in variables mentioned when it comes to their sex and age. The research started with the assumption that less fear of failure will be connected with greater emotional stability, greater emotional competence, more positive fundamental beliefs about myself and with the feeling of greater support. Results showed that less fear of failure is connected with greater emotional stability, positive fundamental beliefs about myself and feeling of great support from family and peers. Based on these results, one can claim that there are no significant differences between seventh and eighth grade students of primary school but there are differences concerned with students' sex, claiming that female students will experience more fear of failure than male students. It is important to work with students so that they experience less fear and so that they could develop in an optimal way.
