The purpose of this study is to offer an educational plan which will help Korean language learners to succeed in a Korean university setting through improved academic writing. To this end, this study analyses native Korean and foreign students' use of Korean composite forms. It is evident from the analysis of 48,000Eojeol texts written by Korean students and foreign exchange students in Korea that exchange students' use of composite forms is limited. The exchange student group performed overall at 76% the level of the native group for composite form usage frequency and range of expression. They made a high number of errors by substituting incorrect composite forms which had a similar meaning to the correct one. Based on these results, this study offers an index of 100 composite forms necessary for exchange students at Korean universities. Implementation of this index in the KFL curriculum will benefit foreign exchange students by improving their writing and furthermore, by improving their overall communicative competence.
