Making a Referral to Early Intervention

Anyone can refer a child to early intervention – parents, physicians, other health care providers, child care providers, social service agencies, early learning programs, etc.  Once a referral is made, it is up to the family to decide whether they want to participate.

Call your local Child and Family Connections (CFC) office to request a developmental evaluation. To find your local CFC office, call (800) 843-6154.

Families should receive a call back within two business days.
