Building Alliances presents the core principles and practices of collaboration that best support transition-aged youth with disabilities—and their families. Val Mazzotti and Dawn Rowe discuss the key roles and responsibilities of youth and their families, school personnel, and community service providers. A series of “research in practice” vignettes illustrates how to implement evidence-based strategies and activities, providing a step-by-step approach to building and facilitating effective collaboration, teamwork, and networking. Building Alliances gives teachers, administrators, and every member of the “transition team” practical tools to facilitate collaboration, empower all participants, and, ultimately, improve post-school outcomes for youth with disabilities.
