The study aimed to investigate the Emotional Intelligence (EI) and its relationship to self-efficacy among school managers. The study was conducted to determine whether school managers develop their EI and whether EI would increase their levels of self-efficacy. The participants of the study were composed of 50 school managers. The participants were selected via randomly method. Mainly due to the study a multidimensional instrument for school managers’ emotional intelligence competence scale (EIC) was developed and validated. Therefore, the present study has used an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to establish the construct validity of the EIC model. The data were collected using quantitative model. For the data analysis Pearson Product-Moment Correlation, Simple Linear Regression and a series of Mann Whitney-U test were conducted (ANOVA non-parametric test) were utilized. The results revealed that there was a positive significant correlation between perceived EI and self-efficacy (r = 53).Thus, it can be stated that EI competence of school managers predicts strong power on their self efficacy perceptions of them. Meanwhile, the study showed that school managers' EI competence and self-efficacy perceptions were high. These findings were compared the samples of female and male. When dealing with result, the perceptions of females on self efficacy were higher than males.
