This study explores the environmental factors that affect the transfer of training among technical education instructors in Nepal. In the exploration, a scale with 40 items was constructed by utilizing Delphi technique. Then, a survey was carried out on 251 instructors who completed instructional skills-related training. The result of Exploratory Factor Analysis (EFA) retained 26 items and showed six factors affecting the perceived transfer of training accounting for 58.8% of the total variance explained which are: (i) organizational transfer intervention, (ii) external monitoring and evaluation (M&E), (iii) local school governance, (iv) management support, (v) social support and, (vi) curriculum standard. Further using Confirmatory Factor Analysis (CFA), the study confirmed the model-fit of three constructs that affect training transfer: organizational transfer intervention, external M&E, and social support. The study concluded that the training transfer is affected by internal and external environmental factors, which are represented by two major driving forces of support and control.
