With increased public awareness of developmental disabilities such as Autism Spectrum Disorder, there are more and more available diagnosis and therapy options for them. It is obvious that services on improving functionality of these children are beneficial. However, there are challenges existing in diagnosis, therapy and intervention service delivery for children with Autism Spectrum Disorder from culturally, linguistically diverse backgrounds due to language barriers as well as cultural differences. In this research synthesis barriers that children from culturally linguistically diverse backgrounds with ASD experienced were examined with discussions and recommendations to combat these challenges and further improve services provision for these children and their families.
