Parents of deaf children are immediately confronted with an unfamiliar reality that quickly occupies a significant part in their lives. This is due, amongst other things, to the almost immediate arrival of a range of professional services, which calls for the parent’s engagement. In this article, we analyze the engagement of hearing parents of deaf children from the theory of social representations. Twenty-nine hearing parents with deaf children from the province of Quebec (Canada) participated in our research combining the evocation technique and semi-structured interviews. Our results have shown how social representations of deafness, parenthood and professional services shape the intensity and direction of the parent’s engagement process with their child.
