This research has further characterized the dimensions of the Five Factor Model (Big Five) in the context of entrepreneurship, based on several studies. Our survey shows that the analysed psychological skills in management, which are important for success in business, are perceived as important in two samples (entrepreneurs and managers in one group and students in second group). Research confirms the assumptions that entrepreneurs/managers and students are aware of the qualitative dimension of management psychological skills important for business. The striking fact was that the psychological variable respect of ethics was ranked in two study groups. The finding confirms the fact that while ethical issues are an imperative of our times, for many businessmen ethics is in last place. The top of the list of students' responses were in skills such as confidence, perseverance and the ability to persuade. Endurance, stress resistance and self-confidence were also identified as priorities in the group of entrepreneurs and managers. From the data, it can be seen that the skills required for business, identified in both study groups as important should be developed and improved through business education.
