The current study tried to empirically examine the influence of enhancing Emotional Intelligence on writing skill. The method of doing the study was giving an "Interchange Placement Test" to the university students who majored in English (EFL learners) in Iran. After selecting intermediate level students for participating in the study, an IELTS test was administered to evaluate the proficiency of the participants at the beginning of the project. Next, the Emotional Quotient (EQ) of the subjects was measured and afterwards, teaching Emotional Intelligence (EI) was started. At the end of a one-educational-year course of simultaneously teaching EI and writing skill, the same EQ and IELTS test was given to the learners. The difference in scores of both EQ and IELTS test were statistically calculated to observe the progress in each issue. The results revealed a significant change both in EQ and in writing skill. The findings of the study could help further the knowledge in the related field.
