The paper is structured in three parts. The first part of the paper defines language, the relationship between the individual and language, and the theoretical laws of language acquisition. Also, the difference between the language as a system and the language as a standard is explained, and the determinants of the standard Croatian language are explained. The second part of the paper deals with the features of communication as an essential determinant of any developed society. The components and forms of conversation as well as personal and psychodynamic aspects of conversation are described. It also determines what constitutes professional communication of educators, what are the communication competencies of educators and what the communication process in an educational institution looks like. Finally, modern and traditional forms of communication between educators and children, educators and parents, and in internal communication in kindergarten are listed. The third part of the paper presents a research whose goal was to determine the awareness of students of the Faculty of Teacher Education about the role of the standard Croatian language in professional communication. The problem of the research was to determine the differences in the awareness of first and third year students of the Faculty of Teacher Education about the role of the standard Croatian language in professional communication and satisfaction with the program content of the faculty on communication and speech. When researching the problem, two hypotheses were made. A survey was conducted on the awareness of students at the Faculty of Teacher Education about the role of the standard Croatian language in professional communication. The results of the survey partially confirmed the hypothesis that third-year students are more aware of the role of the standard Croatian language in professional communication, as well as the hypothesis that first- and third-year students are satisfied with the program's content on communication and speech.
