Transfer is a term used in many fields to describe a change process involving movement of knowledge, skills, or policy from one place to another. The central components of transfer invite the evaluator to conceptualize the change process in terms of a starting point, different understandings of what is being transferred, the medium or mechanism, the concomitant agents, the purpose, and the ending point. Technological models of transfer can be contrasted with learning models of transfer. This means that the educational technology of the intervention might be easily transferred, for example, but not the organizational engagement and inquiry process associated with it. Such scenarios are common in fields where capacity varies widely from place to place. It is therefore crucial to surface what was actually implemented, especially if programs have the same name in various sites, but in reality have replicated very different forms of the program. © Wiley Periodicals, Inc., and the American Evaluation Association.
