A supportive work climate is critical for successful transfer of learning. Influences in the work environment affect the trainee's ability to apply new skills to the job.

The purpose of this study was to identify differences in trainee and supervisor self-perceptions of the factors affecting transfer climate. Additionally, this study examined the effects of supervisor participation in the training program on perceptions of transfer climate. The participants in this study were trainees in a union-sponsored instructor training program and their supervisors. The study found perception gaps between the overall perception of transfer climate and supervisor support. The level of supervisor participation in the training program was not to be a factor in the differences between the trainee and supervisor perceptions. No statistically significant difference exists in the perception of other transfer climate factors: supervisor sanctions, peer support, resistance/openness to change, and feedback/performance coaching. In addition, the study found that supervisor participation in the training made little difference in the perceptions of transfer climate by supervisors and trainees. Studies comparing …
