Quality in the domain of preschool education is explained as constant advancement in the work and thinking of all the factors in the learning community, which is called that way because level of quality is something always rising and is always built on. It is not static category. Partnership, furthermore, is defined as a higher level of connection between caregivers and teachers where both sides clearly see that their joint influence affects the well-being of the child they raise. In this graduate thesis partnership in function of quality of institution is researched. The research was conducted in June 2018 in the kindergartens of Zadar County. There were 45 kindergarten teachers examined, one third of them working in nursery care, one third in regular program and one third in preschool program. High rate of contentment among teachers concerning achieved partnership with caregivers is established. A high level of teacher satisfaction has been established with partner relationships with parents. Furthermore, it can be seen from the results that a modern era characterized by a fast pace of life in this area requires flexibility and innovation, as emphasized in the National Curriculum for Early Childhood and Pre-school Education, which is currently in force in the Republic of Croatia. The results obtained show that the most common and desirable forms of partnership are individual meetings where both sides feel relaxed and can honestly talk. At the top of the ladder are workshops and parents angle while at least home visits, Facebook pages with parents, excursions and travel notes are at least accomplished. By comparing the responses of all three groups of preschool children and by grouping out results, it has been found that there are no major differences in work with regard to the program in which the educators work.
