This research is on the relationship between mothers and fathers in child-rearing attitudes, and parents' child-rearing was conducted to examine the variables that affect attitudes. The research study group in the relational screening model consisted of the mothers and fathers of 324 children (n=648) 36-72 months old children attending preschool education institutions. The Parent Child-Rearing Attitudes Scale (ABTÖ-A) form was used as a data collection tool in the study. Spearman-Brown Correlation Coefficient and CHAID algorithm, one of the decision tree algorithms, were used to analyse the data. As a result of the research, it was determined that democratic attitudes of mothers decrease and repressive-authoritarian attitudes increase as their over-tolerant attitudes towards their children increase; democratic attitudes of fathers decrease as their over-tolerant attitudes towards their children rise, and their democratic attitudes increase as their repressive-authoritarian attitudes increase. Again, it was determined that there is a positive and significant relationship between parents' child-rearing attitudes. It has been determined that the most important factors affecting the parenting attitudes of the parents are the birth order of the children, the education level of the mother, the education level of the father, the working status of the mother and the family structure.
