Transfer of learning from management development programmes has been described as the effective and continuing application back at work of the knowledge and skills gained on those programmes. It is a very important issue for organizations today, given the large amounts of investment in these programmes and the small amounts of that investment that actually translates into an improved individual and organizational performance. This paper describes the testing of the Holton model of learning transfer and suggests amendments to the model where appropriate. A sample of participants on a management development programme within the Irish health service completed the Learning Transfer System Inventory based on the Holton model. The data obtained were analysed using multiple regression and partial correlation techniques. Results indicate that the model does adequately represent the effects of its factors, although a slightly revised model is presented. Important relationships between factors are identified, and the central role of the learners' personal capacity for transfer (hitherto unreported in the literature) and their motivation to transfer in facilitating transfer is highlighted. In practical terms, the tested model can be used as a diagnostic tool by identifying individual, training design and work environment transfer issues in need of attention and by developing strategies to deal with them. It can also be used as a framework for the evaluation of training and development interventions, examining factors outside the traditional range of most training evaluation efforts and providing a more complete picture of the success or otherwise of that intervention.
