Emotional Intelligence (EI) has emerged as a critical factor influencing student success in educational environments. Beyond cognitive intelligence and academic skills, students require emotional competencies such as self-awareness, self-regulation, empathy, motivation, and interpersonal communication to navigate academic challenges effectively. This study examines the relationship between emotional intelligence and student success through a comprehensive review of contemporary literature. The findings suggest that emotionally intelligent students demonstrate higher academic achievement, improved mental well-being, stronger interpersonal relationships, enhanced resilience, and greater adaptability to changing educational environments. Furthermore, EI contributes to classroom engagement, stress management, leadership development, and lifelong learning. Despite growing recognition of its importance, emotional intelligence remains underemphasized in many educational systems. The study concludes that integrating emotional intelligence development into educational curricula can significantly enhance student outcomes and institutional effectiveness.
