Article 12 of the United Nations Convention on the Rights of Persons with Disabilities has been instrumental in driving the development of the concept and practice of supported decision making. An important feature has been the development of “supported decision making pilots.” This paper identifies, describes and analyses pilot programmes providing support for decision making for people with cognitive disabilities in Australia and internationally between 2016 and 2021. It finds that challenges included providing support for socially isolated people and adequately resourcing those programmes. However, most pilots reported positive outcomes for decision makers, adding to the evidence base for claims to be made about the positive impact of supported decision making on the lives of people with disabilities. The pilots demonstrate that, internationally, there is an emerging set of programmes that seek to promote supported decision making incrementally through developing focussed community awareness and practice. While still small‐scale, time‐limited and experimental, with different levels of rigour in practice and evaluation, they provide some foundation and a preliminary evidence base for larger interventions and reforms in the future.
