In this study, I will look at data gathering methods in data-based studies for KAP and Corpus Development Activities for EAP in overseas, and then a design and criteria of corpus for KAP teaching is discussed in detail. a corpus criteria to propose in this study is as follows. 1) The corpus is to be multi-purposeful. 2) It is to be designed so that it is used to study a gap between registers in addition to study a characteristic of a specific register. 3) It is to be a principled collection of electronic texts. 4) It is to be dynamic and genre-independent so that additional data gathering is possible. 5) The depth and width of data sampling reflects a diversity of registers and a relative availability and importance of usage situation. The draft plan of a corpus design and corpus criteria like this implies the conversion of subjects from academic language into university Language, as well as the conversion of directions from in-register into inter-register.
