Many studies emphasize the importance of students’ social skills, but the question is how everyday school practice affects the development of these skills. Socio-emotional skills, according to other authors, relate to the abilities by which a person regulates and manages his own thoughts, emotions and behavior, sets and achieves positive goals, how he experiences himself and respects the perspective of others, establishes and maintains positive social relationships and makes responsible decisions. In this paper, we point out the different components of teacher roles and their approaches that can influence the development of these skills. The results of various research show that changes in the sense of teaching the teachers their social skills, especially in initial education, but also later, increase the awareness of students’ social skills. Empirical findings indicate the key characteristics of successful socio-emotional skills development programs, emphasizing the necessary specific training and coaching of teachers as part of their initial education and professional development, as well as the need for systematic support during the implementation of programs that affect development of these skills in students. The importance of understanding emotions and social skills in students by teachers is emphasized, as well as the development of teachers’ awareness of ways that can influence the development of socio-emotional skills, how to create a positive atmosphere in the classroom and how to adequately respond to different emotions.
