Kim, Hye-jeung Evaluation is considered as systemic and politic aspects in sociocultural aspects as well as internal structure of curriculum. This paper's aims are to survey the ways how Korean language evaluation is performed in this korean social cultural context and how the problems of evaluation is improved. So far, two thema of ‘Performance Assessment’ and ‘Problems and their Improvements of Korean Language Evaluation in high school’ are studied much. And so its study may not have significance, whatever it is principle or progressive. However, its findings show us that lack of expert-knowledges and experiences in development of multi choice test items, and that lack of expert-knowledge of evaluation in various performance assessment making. To solve these problems, first, pre-conference of assessors is planed and harmonious communications is accomplished. And there, plans of evaluation is achieved and viewpoints of evaluation is mediated. Performance assessment and multiple choice test are operated complementary.
