Emotional Intelligence is the ability to recognize, understand, and manage your own and others' emotions. In recent years, there has been a growing interest in Emotional Intelligence, particularly in education, as evidenced by numerous research studies conducted in this area. Throughout the literature, the results emphasize the idea that Emotional Intelligence is strongly correlated with variables such as teachers' and students' self-efficacy, job satisfaction, subjective well-being, and students' positive attitudes. The primary objective of this study is to investigate the relationship between teachers' Emotional Intelligence and Self— efficacy, employing a quantitative research design with a correlational method. Instruments used to measure this relationship are the Quick Emotional Intelligence Assessment for Emotional Intelligence and the Teachers' Sense of Efficacy Scale (short form). The hypothesis was held to explore if there is a positive relationship between teachers' emotional intelligence and self-efficacy. Moderate to strong positive correlations were found between Emotional Intelligence and Self-efficacy variables.
