The mission of Illinois’ Early Intervention (EI) program is to assure that families who have infants and toddlers, birth to three, with diagnosed disabilities, developmental delays or substantial risk of significant delays receive resources and supports that assist them in maximizing their child’s development, while respecting the diversity of families and communities.

The target group is children under three years of age who are experiencing developmental delays in one or more of the following areas: cognitive development; physical development; language and speech development; psychosocial development; and self-help skills. The purpose is o support families in promoting their child’s optimal development and to facilitate the child’s participation in family and community activities. EI services include, but are not limited to: developmental evaluations and assessments, physical therapy, occupational therapy, speech/language therapy, developmental therapy, service coordination, psychological services and social work services.
