Intellectual disability is a disability characterized by limitations in intellectual functioning and resulting in the need for extraordinary supports for the person to participate in activities involved with typical human functioning (Wehmeyer, Buntinx, Lachapelle, Luckasson, Schalock, Verdugo, , 2008).
