Purpose: This paper aims to identify the relationship between organizational learning culture, psychological contract breach, work engagement, training simulation and transfer of training, to examine the effect of transfer of training on organizational citizenship behaviour and to determine the mediating effect of transfer of training on the relationship between organizational learning culture, psychological contract breach, work engagement and training simulation with organizational citizenship behaviour. This study investigated these relationships in the context of public sector organizations in Malaysia. Design/methodology/approach: The data for this study were collected by using the purposive sampling from Malaysian Civil Defence Force or Angkatan Pertahanan Awam (APM) employees who attended a disaster preparedness training programme between March to May 2015. The questionnaire was the main tool for the data gathering. The data were analysed using structural equation modelling technique using AMOS 22 version software. Findings: The findings showed that work engagement and training simulation are the factors that influence the transfer of training, and there is a positive effect of the transfer of training on the organizational citizenship behaviour. The result also demonstrated that the transfer of training is the mediator in the relationship between work engagement, training simulation and organizational citizenship behaviour. Research limitations/implications: This study focuses on public sector areas which is Malaysia Civil Defense Force (APM). No interview session was conducted due to the time constraint in completing this study. Originality/value: This study extends the existing understanding of factors that influence transfer of training and the effect of transfer of training on employees and organization. In other words, through the positive transfer of training, organizations not only attain positive returns on their training investment but also improve the performance and the work attitude of the organization's employees.
