Abstract-International assignment has become a significant concern for both MNCs' business and individual's career growth, therefore necessary efforts have to be taken in order to reduce expatriate failure and to ensure expatriate success. This study aimed at explaining the relationship between individual factors and expatriate performance in short-term assignment. It is intended to provide empirical evidence on how personal attributes, management and leadership skills, and language skills influence expatriate performance.Based on 419 sample of international assignees in 23 host countries assignment, this study reveals that management & leadership skills and language skills have direct and positive impact to performance. However, this study could not discover how personal attributes directly influence performance due to the model on personal attributes statistically not significant. Based on these findings, this paper provides discussion, implications for expatriate research, practical implications, and suggestions for further research.
