This study analyzed the characteristics of the examination essays of international students and statistically verified which of the characteristics of the examination essays influenced the evaluation. Firsty international student essays showed that the higher the linguistic accuracy, the longer the total length, the richer the semantic structure, the higher the coherence, while the less formality of the style. Second, the higher the linguistic fluency, the longer the answer and the richer the semantic structure. Third, the total amount of text was correlated with all of the richness, accuracy of content, and coherence of contents, and strong correlation between richness and coherence of contents. In addition, the factors influencing the evaluation were ‘average number of propositions per topic’ indicating the richness of contents and ‘morpheme numbers’ indicating the amount of text. After interviewing the evaluator and the learner, the evaluators found that linguistic accuracy was not a decisive factor but showed a lack of knowledge of the major if it was below a certain level. In addition, it was found that the precise use of the terminology and the use of the coagulation device are considered important factors. (Yonsei University)
