The purpose of the study was to investigate the role of emotional intelligence in postgraduate supervision: Impact on student success and well-being: A global perspective. The integration of emotional intelligence in postgraduate supervision presents several challenges that can impact student success and well-being. Firstly, accurately assessing emotional intelligence is difficult, as it involves subjective perceptions that vary across contexts. Additionally, supervisors often have diverse emotional intelligence levels and supervisory styles, leading to inconsistent student experiences. Cultural differences further complicate the application of emotional intelligence principles, as emotional expression and expectations can vary significantly across backgrounds.
