IASSIDD sponsors international congresses once every three to four years. These international meetings provide an exciting opportunity for presenting recent findings as well as keynote addresses about major advances in the biological, behavioral, and social sciences related to intellectual disabilities. These advances are also addressed in presentations concerned with progress in the provision of services and supports for persons with intellectual disabilities.

Between World Congresses, the Associations holds Regional Congresses, in Europe, Asia-Pacific, or the Americas.
