This study is aimed to analyze the relationship between teacher efficacy and teacher attitude toward inclusive education reviewed by teaching experiences in private elementary schools in Jakarta and Depok. Ninety-seven private elementary teachers are involved in this research. This quantitative study uses the Teacher's Sense of Efficacy Scale (TSES) to measure teacher efficacy and the Multidimensional Attitudes Towards Inclusive Education Scale (MATIES) to measure teachers' attitudes. The result reveals that there is a significant positive correlation between teacher efficacy and teacher attitude towards inclusive education (r (97) = 321, p < .01). It shows that when the teachers have high efficacy about their competence, their attitude towards inclusive education increases. On the other side, the relationship between two variables, when reviewed by teaching experiences, varies. This study also shows there is no differences in teacher efficacy (F(94)= .212, p > .05) and teacher attitude (F(94) = .335, p >. 05) for the teacher with different teaching experiences. This study reveals that teacher with different teaching experiences have the same belief about their competence as a teacher and have the same attitude toward inclusive education.
