Pedagogical counselling is extremely important as one of the work areas of expert associate pedagogue. Hence it is very important that pedagogues constantly do professional development so they would improve their counseling competencies. One of the options for professional development is education in the field of psychotherapy, reality therapy. There is a very small number of scientific research that explains application of reality therapy in counselling in educational institutions, and in Croatia, there is only one scientific research about application of reality therapy at schools. Therefore, this research dealt with precisely this topic, in order to contribute new knowledge to pedagogical science and practice. Therefore, the aim of this research was to investigate the relationship between pedagogical counselling and reality therapy, and to find possible ways of using reality therapy in pedagogical counselling. A semi-structured individual interviews were conducted on a sample of five pedagogues. The results show that research participants estimate that they did not get key knowledge and skills for quality pedagogical counselling during pre-service training. However, all participants assess that they are competent for pedagogical counselling of students, thanks to additional professional training in the field of reality therapy. They see pedagogical counselling and reality therapy in their work intertwined into an indivisible entirety. Also, they see certain similarities and differences between pedagogical counselling and reality therapy. All of them believe that the application of reality therapy in pedagogical counselling is very effective and suitable for all situations. They conduct it through pedagogical-advisory conversation with students, individually, in pairs or in groups, using various additional methods of work, focusing on building a relationship of full trust with the student.
