This study aims to investigate the relationship of parent attachment, tendency of attribution, and general teacher efficacy of pre-service early childhood teachers. Subjects were 277 students registered in the department of early childhood education at colleges. Data were analyzed with Pearson s correlation, and multiple regressions. The results of the study were as follows: First, teacher efficacy is positively correlated with all attachment of each parent and the communication-subfactor of attachment- and all subfactor of attribution except instability. And there were some significant correlations between parent attachment and tendency of attribution. Second, the factor affecting teacher efficacy of pre-service teacher is controllability, the subfactor of attribution. On the basis of these results, some implications about the plan for improvement of teacher efficacy in the teacher training course and suggestions for further study are proposed.
