Abstract: Early intervention plays a very important role in social adaption and learning of the children who are at risk.It has been moved to a more empirical direction,that is to say,there has been a substantial movement toward developing and implementing evidence-based services in the early intervention field.We introduce 3 concrete evidence-based programs targeting children who are at risk.Moreover,we will consider two issues in early intervention.

Key words: developmental disability, children at risk, early intervention, evidence-based services, review
