What organization joined the ICC in 1986?

The International Federation for the Persons with an Intellectual Disability (INAS-ID) is indeed the organization that joined the International Commonwealth of organizations (ICC) in 1986. This federation was established to promote and develop sports for individuals with intellectual disabilities, facilitating their participation in athletic events and competitions. By joining the ICC, INAS-ID gained recognition and support, allowing for an increased focus on inclusivity in sports and the opportunity for athletes with intellectual disabilities to participate at both national and international levels.

The other entities mentioned, such as the International Committee of Sport for the Deaf, International Paralympic Committee, and International Wheelchair Basketball Federation, play crucial roles in the sports landscape, each with their own missions and focuses on different groups of athletes, but they do not share the same timeline regarding the ICC.
