This study was performed with a view to examine the nature and difference of EFA(Exploratory Factor Analysis) and CFA(Confirmatory Factor Analysis), and to compare the analysis process and result of EFA and CFA with the same data. The result of empirical analysis was as follows. Meanwhile, p.1, p.3 was removed owing to hampering the convergent validity in EFA, p.3 was removed owing to hampering the discriminent validity in CFA. EFA was reduction process of muti measurement variables to a few factor, but CFA was understanding and confirmatory process of measurement and latent variables' relation. Eventually, this study showed that EFA and CFA used different methology, thus the different outcomes appeared although using the same data, and implicated resonable application of methology according to given data.

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.
