This article addresses the issue of supporting the development of children diagnosed with speech disorders, while also providing information on speech therapy prevention for children who do not exhibit speech-related difficulties. The aim of the article is to outline how teachers can support the development of their students, both those with speech disorders and those without any difficulties. The article emphasizes the importance of an interdisciplinary approach to child development, in which the child’s immediate surroundings, including the teacher, play an essential role. Speech development is a crucial aspect of human life, beginning in the prenatal period. To effectively support a student with speech difficulties, it is necessary to understand the process of speech acquisition, the pathomechanisms underlying common speech disorders in children, and the basic therapeutic interventions used by speech therapists.
