Objective: This study examined the relationship between child care teachers’job satisfaction, teacher-parent partnership, and teacher- child interaction in order to improve the quality of child care. Methods: Self-report questionnaires were used on 321 child care teachers and data were analyzed using descriptive statistics, Pearson correlation and Structural Equation Modeling Analysis. Results: First, significant correlations existed among variables except the relationship between payment/promotion and other variables. The results showed that child care teachers’job satisfaction had a significant and direct influence on teacher-child interaction, and teachers’ job satisfaction was partially mediated by teacher-parent partnership on teacher-child interaction. Conclusion/Implications: The findings confirm that teachers’ job satisfaction and teacher-parent partnership are preceding factors for positive teacher-child interaction. Significant attention should be paid to child care teachers’psychological satisfaction and teacher-parent relationships to promote the quality of child care and the positive interaction between teachers and children.
