In Ireland’s steadfast dedication to human rights, social equity and justice, the imperative to amplify the voices of all individuals, regardless of their unique experiences or age, stands as a paramount principle. Guided by both international agreements such as the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) and the United Nations Convention on the Rights of the Child (UNCRC), and national agreements such as the National Strategy on Children and Young People’s Participation in Decision-Making (2015), the National Framework for Children and Young People’s Participation in Decision-Making (2021), the Children and Young People’s Participation in Decision-Making Action Framework (2023-2028), and Young Ireland: The National Policy Framework for Children and Young People (2023-2028), this literature review – commissioned by the Department of Children, Equality, Disability, Integration and Youth (DCEDIY) – examines the available evidence concerning the participation of disabled children and young people in decision-making. This evidence is needed in order to inform the development of a toolkit on how to meaningfully and effectively involve disabled children and young people in the decision-making process and approach participative consultations and initiatives in the most accessible and inclusive way possible.
