The aim of this is to determine the quality of family functioning in the Republic of Croatia. The paper seeks to examine the quality of family functioning in terms of gender, age and parental education, place of residence and family structure. In order to determine differences and correlations in the quality of family functioning, the scale “Quality of family functioning in the Republic of Croatia” was used, which included 668 respondents from the territory of the Republic of Croatia. The results of the research show that there is a statistically significant correlation between the quality of family functioning and the age of parents. In the work, the family is viewed as a social, educational and ethical community whose primary function is to raise a child in accordance with the social and ethical values present in contemporary society. For the child, the family is of paramount importance because it encounters first life experiences in it and the child's family represents the environment in which it finds warmth. Throughout history, the family structure has changed due to historical, economic and cultural changes. Initially, families had one foster parent, while modern families have two foster parents, fathers and mothers, which is why the upbringing of children is left to third parties. Inside the family, upbringing represents an interpersonal relationship filled with love, understanding, honesty, trust, hope, desire, joy and disappointment, and the family represents the connection between the child and society and at the same time prepares the child for life in society. Upbringing within the family has an impact on the child's later progression. Educators, who represent childcare professionals, play an important role here. Namely, through their knowledge and skills, they can support parents with education and counseling to protect the best interests of the child.
