The purpose of this study was to validate Preschool Child Observation Record-II developed by High/Scope for Korean preschool children. The subjects of the study were 255 children aged three to six attending child care centers and their head teachers. They were observed for at least two months and completed the Korean version of Child Observation Record-II(K-COR-II). K-COR-II consisted of six categories and 32 items which had five-level-rubrics. The results from an exploratory factor analysis identified one dimension of the scale, there was no evidence of discriminant validity even after face validity was examined. The concurrent validity and internal consistency of the revised scale were relatively high. Also, the mean between the upper and lower groups with regard to item discrimination showed significant difference. It was concluded that K-COR-II can be used as a valid and reliable instrument to various aspects of preschool children's development.
