This research focused on the attitudes toward teacher trust, parent-teacher relationship, and parents engagement for parents of young children. It explores their configurations about parents' trust in teachers and teachers' recognition of educare thoughts of young children. The researchers were also examined the effects of parent-teacher relationship and parent-teacher communication on their engagement in preschool activities. The researchers developed the 'Questionnaire on Attitudes towards Parent-Teacher Communication and Engagement for Parents of Young Children' with five factors, including teacher trust, teacher-young children interaction, parent-teacher relationship, parent-teacher communication, and parent engagement. We used partial least squares to verify different latent factors and path models. The results showed that parents' attitudes regarding engagement in preschool practices and activities were heavily influenced by their perceptions of parent-teacher communication, and parent-teacher communication is framed by their perceptions of teacher-young child interaction, and parent-teacher relationship. These related attitudes were also affected by the parents' trust in teachers.
