The present study shows that training motivation acts as an essential mediating variable in the relationship between the training environment and tacit knowledge transfer. This study was carried out at a policy-making government organization in Malaysia. 185 survey data were included in the analysis and seven scales were used to collect data. The study sample has satisfactorily met the criteria of measuring and testing the study model. The study data was analyzed using SPSS and SmartPLS programs. The findings of the structural equation modeling show that training motivation mediates the effect of the training environment on tacit knowledge transfer. According to this study's findings, management's ability to create an environment of encouragement and interactive communication during training will be a significant precursor to eventual favorable employee outcomes.
