There has been continued debate regarding educational policies and practices regarding the lifelong learning social order with significant focus upon the preparation of educators of children and youth for this global lifelong learning society. However, there has been limited discussion and research regarding the professional preparation of lifelong learning adult educators. This article investigates the current status of graduate professional programs to prepare lifelong learning adult educators (individuals who are prepared and credentialed through a professional graduate master's degree in adult education and human resource development). Because of differing international policies and structures of graduate education, this discussion will present a comparative examination of current structures and characteristics of master's degree programs at two institutional sites located in Denmark and the USA. Current objectives, characteristics, and understandings of graduate professional preparation programs will be delineated between these two case studies. Contextual issues and influences in the preparation of lifelong learning adult educators will be discussed, with comparative discussions of cultural norms and policies regarding graduate professional preparation, innovative programmatic and instructional efforts, engagement of theory and best practices in lifelong learning, and comparative cultural differences between program students and faculty.
