Schooling transitions are often challenging experiences for students with intellectual disability and/or autism spectrum disorder (ID/ASD), their families, and their teachers. Transition processes, particularly planning, can facilitate successful transitions from primary to secondary schools, and to postschool settings. Bronfenbrenner's ecological model served as a theoretical framework to examine parents’ and teachers’ experiences with transitions for students with ID/ASD attending special schools. The authors interviewed 14 carers and 13 teachers of students with ID/ASD attending special government schools in New South Wales. The interviews were analysed using content analysis. The findings of this small-scale Australian study indicate that although transition practices varied widely by school, both parents and teachers perceived that more can be done to support students with ID/ASD during these times. School–home collaboration and access to information about postschool settings were areas that were emphasised by both groups. Furthermore, the lack of student involvement in transition meetings was of great concern, given that student-focused planning is a well-established evidence-based transition practice. The processes that are implemented to support students with ID/ASD require closer scrutiny, as results revealed inconsistencies in transition planning across schools, and both parents and teachers suggested ways to strengthen transition processes.
