Students with autism and intellectual disabilities experience many transitions during their schooling, and a large body of literature is devoted to best practices in transition planning and support. The Taxonomy for Transition Programming 2.0 is a research-based model that provides best practice suggestions to guide the planning of various transitions and contexts. The researchers aimed to use the current qualitative study to discover the transition planning practices used to support students with autism and intellectual disabilities in inclusive school settings when transitioning from primary to secondary schools and from secondary school to postschool life in New South Wales (Australia). The practices that emerged were then examined for alignment with the Taxonomy for Transition Programming 2.0. The inductive content analysis of interviews with 8 parents and 13 teachers indicated that although most of the areas of the Taxonomy are represented in the planning processes, there is room for improvement, particularly in the areas of formal individual education program and transition planning, student involvement, information sharing, and program assessment. The results highlighted the importance of formal student- and family-centred planning processes to the success of both transitions. The results were used to make further recommendations for future research, policy, and practice.

There are no Commonwealth or state laws in Australia that require educational authorities to provide individualised transition plans (ITPs) to secondary students with disabilities. It is argued that, in lieu of legislation, Australia's signed commitment to international treaties and national policies obliges educational jurisdictions to provide ITPs to secondary students with disabilities to improve the postschool outcomes for this vulnerable population. Document analysis methods were used to analyse these international treaties and national policies for statements aligned with evidence-based transition skills and predictors. Almost 90 transition-aligned statements were found, accounting for all evidence-based transition skill categories and most of the transition predictor categories. Implications for policymakers and educational jurisdictions are discussed.
