In the context of immigration, there are numerous challenges facing families living with a child with special needs. First, they require access to support services in order to provide continued adequate care to the child. In order to establish an update of the background knowledge on the use of support measures, a scoping review was carried out. Twenty scientific studies were selected from database queries to determine the types of services used, the components modulating this use and the evolution of needs in assistance measures. Informational support is found to be the most present in the studies. Among the factors defining the use of support services, communication and cultural components are distinguished by the number of studies in which they stand out. According to the selected studies, there is little documentation on the evolution of assistance uptake through time. Parents’ choice of support modalities should be explored further.
