Part C Eligibility
Part C eligibility is determined by each state's definition of an infant or toddler with a disability (34 CFR §303.21) which must include: an infant or toddler with a developmental delay and an infant or toddler with diagnosed physical or mental conditions with a high probability of resulting in developmental delay.
Developmental delay is "measured by appropriate diagnostic instruments and procedures" to determine the developmental functioning in each of the 5 developmental areas: cognitive, physical including vision and hearing, communication, social or emotional, and adaptive.
Included in the evaluation process is the use of the informed clinical opinion of professionals experienced with development of infants and toddlers.
An infant or toddler with diagnosed physical or mental conditions with a high probability of resulting in developmental delay include such conditions as chromosomal abnormalities; genetic or congenital disorders; sensory impairments; inborn errors of metabolism; disorders reflecting disturbance of the development of the nervous system; congenital infections; severe attachment disorders; and disorders secondary to exposure to toxic substances, including fetal alcohol syndrome.
States may choose to serve children at risk for disabilities in their eligibility definition (34 CFR §303.21).
State and Jurisdictional Eligibility Definitions for Infants and Toddlers with Disabilities under IDEA Part C
This database of State and Jurisdictional Eligibility Definitions for Infants and Toddlers with Disabilities Under IDEA Part C provides the following information about the state or jurisdictional eligibility policy:
- Definition of developmental delay
- At-risk for developments delay policy (if applicable)
- Link to state eligibility policy and additional links to other policies if available

Part C Child Count data is one measure that can assist states in determining performance related to early identification and provision of services to children with disabilities. Part C Child Count data reports reflect the number of children with IFSPs served by each state (e.g. birth to one, one to two, two to three and birth to three) and includes the National Average in each of these categories and over multiple years.
