This research is on sexual identity in Korea in the context of Korean education system. For this purpose, this research examines male and female title. Title has not been the main subject in Korean education, and only family title has been studied in a limited way. In Korean, female title is more advanced and diversified compared to male title. Female title is diversified based on age, appearance, and marital status, and many of them have lost its original meaning from a historical point of view. In Korean education material, male people are mostly identified by their social position or job title. On the contrary, most of female people are called clerk, employee, waitress, 아가씨 or 아주머니/아줌마. Also, in Korean education material, customary perception from traditional Korean society still exists with its 'title', 'occupation', 'behavior', and 'expression'. Although institutional discrimination between male and female has been diminished in Korea, dichotomy between male and female role has become more visible.
