The paper analyzes the education system of private security personnel in Slovenia. Through the presentation and comparison of education and training programs for obtaining national professional qualification (hereafter: NPQ) and secondary and post-secondary education programs, it indicates shortcomings and opportunities for improvement. The theoretical part used a descriptive method and an analysis of professional literature, legal, and by-laws in the field of private security and education. On this basis, the historical background and current regulation in the Republic of Slovenia were presented. The analysis and comparison consisted mainly of education programs and programs for obtaining NPQ. In the empirical work, the focus group included security personnel based on different ways of obtaining education, certification or ID card for security personnel, as well as security managers and lecturers at various levels of education and training. The findings show that the subjects in the field of private security in the training and education programs are very similar in content, they are also comparable in terms of duration and the ratio between theoretical and practical work. Since the programs are not adequately upgraded according to the level of education, it would be necessary to update the programs and at the same time ensure the competence of the practitioners of the pedagogical process. It would also make sense to regulate the conditioning of the approach to training for different NPQs with work experience. The findings are useful especially for creators of education and training programs and proponents of laws regulating private security, secondary and higher education, and NPQ. They could also be important for other countries that have a similarly organized private security personnel education system and/or want to reform their existing system.
