This monograph provides a review of the literature on the transition of students with disabilities into the adult world and an analysis of various models of transition that have emerged in western Europe in comparison with those in the United States. An introduction identifies key definitional issues in transition: defining the population, transition, integration, and paid work. The second section looks at approaches to transition policy and planning, including components of U.S. transition models and transition models from the following western European nations: Switzerland, United Kingdom, Holland, France, Italy, and Denmark. The third section discusses issues in transition policy. These include the extent of school integration, coordinated planning and follow-up from school to work and community living, the extent of integration in the post-school work and community living options, and the attainment of some form of competitive employment.
