•The purpose of this review was to determine the importance of early diagnosis and intervention during infancy, leading to significant outcomes which include improvements in communication skills, receptive language and social interaction in children with ASD.

•Nass et al.,(2016) described ASD as a “heterogeneous group of biologically based, neurodevelopmental disorders characterized by impairments in two areas: deficits in social communication and social interactions and restricted plus repetitive patterns of behavior, interests, and activities”

•The findings showed that early diagnosis and referral to intervention makes a significant impact on children with ASD showing improvements in many areas of delay including receptive communication, adaptive behavior, social interactions, social approach, joint attention, and IQ.

•The finding found when applying early intervention children maintained the gains in all areas with no to minimal regression loss of skills after a two year follow-up.

•The findings indicated that most providers that incorporate screening tools into their practice are referring to early intervention centers and the children are starting intervention prior to official diagnosis.

•The findings showed that most children are being diagnosed at appropriate ages ranging from 30-120 months.
