In spite of its arguable limitations, Goldthorpe's class scheme seems to allow a more fine-grained way of measuring social class. However, only a few sociologists have undertaken an investigation of empirical validation of this class schema. This study attempts to assess the validity of the Goldthorpe class scheme in South Korean context, following Evans (1992) and Evans and Mills (1998)'s studies. After pre-examining a multi-cross table by class indicators, this study analyzes latent class models, and examines to what extent the latent class structure matches the types of occupational classes identified on theoretical grounds by Goldthorpe. The author finds that Goldthorpe class scheme is roughly applicable to class structure in South Korea in that there is a clear distinction between employment relations: service relationship versus labor contract. Definitely, a four-class latent model that this study used clearly shows the existence of manual workers regulated by labor contract in a similar way with Goldthorpe class schema. However, this does not mean that Goldthorpe class schema is clearly valid. There are a lot of inconsistencies that should be investigated in further study. In order more clearly to understand class structure in Korea and to assess Goldthorpe class schema, there needs the more accumulation of studies investigating this issue. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]
