Leadership is a process in which one person influences others to achieve a common goal. This study aims to investigate the effect of authentic leadership practices on training transfer with proactive personality as the mediator. A sample of 420 participants out of 461 (response rate=91.1%) completed the survey that addresses authentic leadership, proactive personality and transfer of training. Out of the 420 participants, 385 clean data were used in the study after 35 data outliers were identified and removed to prevent distortion of statistical tests and inferences.
