The North Carolina Early Intervention Branch (NCEI) is a part of the N.C. Division of Public Health. It is the lead agency for the N.C. Infant-Toddler Program (ITP). The Infant-Toddler Program provides supports and services for families and their children, birth to three who have special needs. Research shows that this time period is critical. It offers a window of opportunity to make a positive difference in how a child develops and learns. Eighteen Children's Developmental Services Agencies (CDSAs) across North Carolina work with local service providers to help families help their children succeed.
