The higher Korea`s international status and global interest in Korean language get, the more needed Korean language instructors who are not only professional in teaching Korean but also cross-culturally sensitive are. Nevertheless, training or education programs for enhancing Korean language teachers` cultural competence have not been widespread enough. However, majority of instructors who teach Korean as a foreign language bump into many different kinds of cross-cultural scenarios interacting with their international students while still not being culturally knowledgeable enough to deal with cultural diversity in appropriate ways. Therefore, it is highly necessary to develope their own cultural competence and cultural intelligence(CQ) through which they will be able to overcome various cultural challenges they can experience. In this reason, I suggested ‘a Cultural Self-study Module’ for Korean language teachers and tried to testify to its effectiveness through an experiment. The results of the experiment have shown some positive aspects in the relation between cultural self-study and CQ enhancement. That is to say, 84% of 50 applicants obtained higher CQ after performing cultural self-study and the total CQ average also went up by 11.1%. When considering the importance of Korean language instructors` cultural intelligence, it is indispensable to do more research on what to teach and how to train them to develop their own CQ.
