The purpose of this study is to examine the factorial validity of the Career Growth Scale (CGS), which was originally developed by Weng and Hu. Using a sample of 230 South Korean employees, we confirmed that Weng’s four-factor model was appropriate for assessing career growth. When comparing Korean with Chinese employees, Korean employees had relatively higher scores on two CGS subscales, Career Goal Progress and Promotion Speed. Results indicated that the CGS was a valid instrument to measure career growth in Korean employees, suggesting the possibility that the CGS could be used regardless of cultural background. Implications for future research, practice, and limitations are discussed.
