The absence of mutual respect and tolerance in preschoolers is getting stronger. This research aims to elaborate on the manifestation and causes of intolerance and examine the effect of positive parenting on intolerance. This research is field research using survey and experimental methods. The survey was been conducted to identify teacher needs as a basis for developing a positive parenting module. Experiments were been conducted to see the effect of positive parenting on intolerance. The subjects of this research were 129 pre-school children in Yogyakarta who were been selected using a purposive sampling technique. Data analysis uses qualitative analysis techniques (reduction, display, and conclusion) and quantitative (t-test). The results showed Intolerance of many pre-school children occurs around religion and morals (blaming and hating the religion of different friends, not wanting to share and make friends with friends who are different from themselves). Causes of intolerance include imitating songs, watching television, and the internet, imitating parents, friends, or teachers. Positive parenting affects the intolerance of pre-school children, as indicated by the value of t = 3.396 and p = 0.000, which means that positive parenting can reduce pre-school children's intolerance. Therefore, sustainable positive parenting needs to be implemented within both the family, school, and community, so that intolerance in pre-school children does not arise.
