The study examines the topic of educators' competencies, primarily focusing on communication as a support for children's speech and language development. It provides a detailed analysis of the development of speech and language in children from the prenatal period up to school age, with particular emphasis on Albert Bandura's social learning theory. According to Bandura's theory of social learning, children learn by observing and imitating, which is an important aspect of language and speech development. The paper also outlines the competencies of educators that are crucial for effective communication with children, including the youngest ones who primarily use gestures and preschool-aged children who are already proficient in spoken communication and early literacy. The study highlights that high-quality educator communication plays a key role in encouraging children's language development. Stimulating activities in kindergartens used by educators to enrich children's vocabulary and improve their communication skills are specifically addressed. Activities such as storytelling, role-playing, singing songs, and engaging in conversations are described as methods that significantly contribute to children's speech development. The paper concludes that the quality of educators' communication with children is important for establishing a positive relationship between educators and children, achieving educational outcomes, particularly fostering children's language and communication development, and the overall development of children's language and communication skills.
