Qualitative data were gathered from trainers regarding best practices for supporting training transfer. Using content analysis, findings suggest interventions for bolstering transfer are best carried out in the work context and design/delivery phase, take place after training or during, and involve trainers and supervisors. However, trainers across different job levels tended to disagree where and when to best support transfer. Supervisory support activities, performance opportunities, interactive training, measuring transfer, and job-relevant training garnered top attention.
