In order to determine CSEB according to some variables which are gender. class level, type of high school, and giving lecture, the scale was implemented 116 prospective chemistry teachers. LISREL 8,71 and SPSS statistical programs were utilized to analyze the collected data. It was confirmed whether CSEB scale has two factors or not by calculating fit indexes. Independent and ANOVA t-tests were used to outline if there was a significant difference between self efficacies of prospective teachers according to gender, class level, type of high school and giving lecture. The results of confirmatory factor analysis showed that fit indexes values were found high and verified structure of the scale with two factors.
