Professional competency of the pre-school teacher plays a quite determinant role in enhancing the quality of pre-school education. This determinant role of the professional competency of the pre-school teacher is of great importance in teacher's planning and practice. The research aims to determine the extent to how teacher's sense of efficacy accounts for their classroom management skills. Two hundred twenty-three pre-school teachers who work at pre-school institutions participated in the study. Embedded mixed design, where both quantitative and qualitative methods were employed, was used in this study. It has been found that the level of teacher's sense of efficacy belief is a predictor of the classroom management skills of pre-school teachers. Quantitative analysis showed the relation between self-efficacy of pre-school teachers and their perceptions of classroom management skills in relational with the professional variables. It has also been noted that the findings of detailed interviews support the quantitative results.
