The purpose of the study was to examine the differences in personality, motivational factors and career decision-making difficulties between career decided and undecided students. The predictive value of some personality and motivational variables for secondary school students’ career decision-making difficulties was also investigated. 641 students of the fourth class of grammar school participated in the study. The results show that there are differences between career decided and undecided students in most of the personality variables. Career decided students make their decisions more self-confidently, are less panic-stricken and avoid decision-making less compared to undecided students. They are higher in extraversion, conscientiousness, openness and emotional stability, are more competent and report having more self-control and fewer career decision-making difficulties. The most important predictors of students’ career decision-making difficulties are: a less panic-stricken and impulsive decision-making style, extraversion, emotional stability and competence in self-regulation
