The development of interpersonal and intrapersonal competencies is crucial for the development of a self confident individual, competent for social exchange within the community. It is important to emphasize that the development of interpersonal and intrapersonal competencies does not happen by accident, but requires professional’s intervention. The encouragement and the development of the previously mentioned competencies should start from the child’s birth, especially during the preschool period which is crucial for the development of socio-emotional skills. The Montessori pedagogy is a valuable example of the organization, structure, and meaningfulness that fosters the development of interpersonal and intrapersonal competencies in children. Orientation to the child, freedom to choose adequate activities, stimulating atmosphere, prepared environment, didactic materials and dedicated educators are a prerequisite for satisfying all developmental needs of a child, but also for the development of the child’s socio-emotional competence. It is the role of the educator that is crucial for the successful functioning of such an organized approach, but also for understanding the needs of the child at all times. Therefore, the main objective of this research was to interview Montessori educators using interview methods on the ways in which they promote the development of interpersonal and intrapersonal competencies in children, and to examine the problems of these in general. The research has shown that Montessori kindergartens nurture and foster the development of interpersonal and intrapersonal competencies through all activities, by preparing a supportive environment, through a method of conversation and mutual respect. It has been shown that the role of the educator is crucial for achieving a comfortable and stimulating environment that provides a holistic approach to learning and teaching.
