This research aims to locate the impact of integration in ordinary school schoolboys in situation of handicap on the social representation of the handicap of the other pupils of the class. The effect of the integration experience (the fact of to belong to a class which integrates or not a student with a disability) as well as the visibility of disability (visible handicap like the cerebral palsy versus nonvisible, such as severe disorders of the learning) were particularly studied. The results show that students have a common representation of disability primarily directed towards a deficit point of view.However, this representation varies on the level of its peripheral elements as if confrontation with the disabilities led the schoolboys to be detached from the medical aspect of the disability for more being interested in the personality of their handicapped comrades and becoming aware of the difficulties which the latter encounter.
