Partnership with parents is a developmental process that involves numerous activities aimed at involving parents in the work of the kindergarten and achieving better communication between parents and educators. Communication platforms are one of the tools for achieving better communication between parents and educators and better involvement of parents in the work of the kindergarten. By using a communication platform, parents can be involved in the work of the kindergarten regardless of the time and place they are in. Educators, by using a communication platform, have the opportunity to provide parents with insight into their child's activities in the kindergarten and inform them about the development of their child's competencies. Through communication via a communication platform, interaction between parents and educators, connectivity and collaboration, two-way communication, and partnership are achieved. The aim of the research is to explore the possibilities of establishing a partnership between parents and educators in the kindergarten using communication platforms. The research sought to determine the possibility of positioning parents as engaged subjects of the educational process and the use of communication platforms as tools for establishing a partnership between parents and educators. The theoretical part of the paper contains defined forms of cooperation between parents and educators and models of parental involvement. The theoretical determinants of society, communication, and previous research on the use of communication platforms are explained. The empirical part of the paper contains survey and action research. For the research, a questionnaire for parents and educators was used, formulated according to Hornby's model of parental involvement. The questionnaire included educators and parents of rural and urban kindergartens in the eastern part of the Brod- Posavina County. The results of the initial questionnaire provided guidelines for educators in planning the action research, which was conducted in one kindergarten in three educational groups. Six educators from a kindergarten located in the rural part of the Brod-Posavina County participated in the action research. By using communication platforms in the family-educator relationship, parents had insight into the educational process, equal opportunities for communication with educators, and the possibility of involvement. The research is important because activities through a communication platform enabled the positioning of parents as engaged subjects of the educational process and played a role in the development of partnership relationships. Since the survey provided a current insight into the state of partnership between parents and educators in the eastern area of the Brod-Posavina County, the possibility of determining the state of partnership using a questionnaire is possible on a larger sample. The action research provided a deeper understanding of the development of partnership relationships, insight into activities that contribute to the development of relationships, and the benefits that Facebook groups provide for the child, educators, and parents.
