The employment of parents and a fast paced lifestyle redirected care and education from parental sphere to educational institutions. That is why educators play a key role in the upbringing of a child. In order to provide safe and favourable conditions for children’s development, it is necessary to bring the relationship between parents and educators to the level of partnership. In the beginning, educators take the initiative, encourage parents and inform them, and then, with quality communication, parents gradually get more involved and actively participate. The highest level of cooperation is represented by a partnership, in which both parties have a common goal the wellbeing of the child. In a partnership relationship, parents do not hesitate to ask for advice, provede information or express their point of view, and educators are ready to encourage parents in their role. This brings into focus the importance of communication, which leads to the development of the partnership. In this paper all four communication styles are explained, namely: submissive, aggressive, passive- aggressive and assertive communication style. Consequently, it is emphasized that an assertive style of communication is the most suitable way of communication since its goal is to find a solution to a problem. Assertive communication does not focus on blaming either part on the personal level, but discusses their actions. In addition, it is important to respect onerself and the others when expressing one’s own views. This paper contributes to the understanding of the role of an assertive style of communication in developing a partnership between parents and educators.
