Corporations are increasingly relying on cross-cultural training of expatriate managers to reduce personnel costs. Previous research has shown consistent validity for different training methods. This meta-analysis investigated the available empirical literature, identifying 16 studies for expatriate adjustment (total n=2270) and 25 studies for expatriate performance (total n=2490). Mean effect sizes were lower than in a previously published meta-analysis and were significantly different from zero for both performance (r=.26) and adjustment (r=.13). Until the effects of potential moderators are better understood, prescriptions for cross-cultural training design should be made cautiously.
