If the process specified in this paper is implemented as described, the outcome is an increased probability that a student, and his or her family, will be better prepared to deal with the demands of adulthood that the young adult will face upon leaving school. In the United States, the transition assessment and planning process is typically documented in the student’s IEP. However, the long-term impact of effective transition planning is reflected in successful adult outcomes for those students who benefit from systematic preparation for life after secondary school.
