The Global Research Agenda for Children with Disabilities (the Research Agenda) is a strategic framework that identifies priority research areas -- defined through a global research prioritization exercise -- to close critical evidence gaps, inform inclusive policies and programmes, and guide effective investments that support children with disabilities. It outlines an implementation strategy to bridge the gap between research and practical, policy-relevant and programmatic outcomes. The Research Agenda offers a structured approach to evidence-based decision-making, ensuring that children with disabilities and their representative organizations of persons with disabilities (OPDs) are meaningfully engaged at global, regional and national levels. The Research Agenda also plays a key role in advancing the objectives of the United Nations Disability Inclusion Strategy (UNDIS), as well as agency-specific frameworks such as the UNICEF Disability Inclusion Policy and Strategy (DIPAS). By guiding the generation of robust evidence, identifying key research gaps, and promoting inclusive and participatory methodologies, the Research Agenda strengthens the capacity of donors, researchers and decision-makers -- including UNICEF, its partners and other agencies -- to embed disability inclusion across policies, programmes and evidence initiatives, including data, research and evaluation.
