The IDA was instrumental in establishing the International Disability Caucus, the network of global, regional and national organisations of persons with disabilities and allied NGOs, which became a key player in the negotiation of the UNCRPD. The IDA is now a major international player in support of the UNCRPD at international, national and regional levels. The IDA governing body is composed of the chairs of all its member organisations. It meets at least twice annually, usually in Geneva or New York. The IDA, with its unique composition as a network of the foremost international disability rights organisations, is the most authoritative representative voice of persons with disabilities and is acknowledged as such by the UN system both in New York and Geneva. The IDA is also committed to building the capacity of national DPOs with special attention to the global South, in order to support national efforts toward ratification, implementation and monitoring of the UNCRPD.
