Transition to adulthood for young people with diabetes is a critical milestone in their lives. It is a time when many facets of life are changing simultaneously. It is most important to recognize the special needs of adolescents with diabetes during this period. A successful and smooth transition of diabetes care should be based on a well-organized plan that includes the young person and the family. The process should be facilitated by collaboration between the pediatric and adult clinics. It should be guided by structured policies and guidelines, including posttransition evaluation. Finally, it should be a process, not an event. The school nurse can play a critical role in its success.
