This report outlines a method for learning about the internationalization processes at institutions of adult and higher education and then provides the analysis of data gathered from the researchers' own institution and from site visits to three additional universities in the United States and the United Kingdom. It was found that campus internationalization requires a deep understanding and appreciation of the institutional context. In addition, although elements of internationalization may be implemented, the findings indicate there is a need to underpin these approaches with (a) a shared understanding of what internationalization is and the ways it should ultimately impact student learning within an institution and (b) a collection of assessment methods for evaluating internationalization efforts and learning outcomes. Implications and recommendations for further research are also offered.
