The competitiveness of companies in the demanding market is achieved through various factors such as the quality of goods and services, compliance with deadlines, solvency, but human capital and organizational knowledge are increasingly becoming more important. In times when only change is a constant, human capital and organizational knowledge can be developed through employee education and training. The research of this paper was focused on business trainers and a better understanding of employee education that takes place within different organizations and companies. For an internal business trainer, sole professional knowledge in the field of business is not enough, but it is also necessary to work and improve in many areas and thus systematically adopt new skills and knowledge as well as improve competencies. The aim of the research was to examine which knowledge, qualities and competencies do business trainers consider desirable in their work and how they assess the degree of development of their own competencies. The research was conducted through an online survey on a convenience sample of 32 respondents who are business trainers in seven different companies. The analysis of the obtained results indicates that business trainers are significantly familiar with the desirable qualities and competencies of business trainers and that they are aware of the need for continuous development and improvement in this business role. This research has shown how business trainers perceive their own competencies and performance. However, for a more complete and objective picture, future research should also include participants in their training as well as other criteria for assessing the success of business education.
