Trainee perceptions of transfer climate have been found to be an important predictor of transfer of training. Self-efficacy has also been identified as an important individual difference related to transfer. Few studies have examined how these variables work together to enhance or limit performance following training. In a field study of 37 trainees, supervisors were randomly selected for training in how to provide their subordinates with opportunities to use the learned skills on the job and reinforce attempts at application. It was found that trainees who had a supervisor who participated in the intervention perceived a better transfer climate than trainees whose supervisors did not participate in training. Transfer climate mediated the relationship between self-efficacy and transfer of training. (Contains 2 tables and 1 figure.)
