Communication is an essential part of life, both private and professional. In educational institutions, communication is of great importance for business efficiency, like in all other forms of business management. Through communication, people share their views, needs, and intentions with other people. Each of us uses different style of communication and manners of expression. Every day, educators communicate with parents, children, other educators, professional associates and other employees. Without such cooperation, the educational system would not function well, which would have particularly negative impact on children and their welfare. Therefore, proper communication skills are fundamental for successful communication. Only good communication skills can create cooperation and thus improve the work of any educational institution. This paper attempts to explain the importance of different forms of communication and cooperation in educational institutions, as well as possible obstacles that may occur, both at the level of the individual and the entire organization. In order to avoid these obstacles, various authors have presented some of the methods for more effective communication.
