(a) As used in this part, infants and toddlers with disabilities means individuals from birth through age two who need early intervention services because they—
(1) Are experiencing developmental delays, as measured by appropriate diagnostic instruments and procedures, in one or more of the following areas:
(i) Cognitive development.
(ii) Physical development, including vision and hearing.
(iii) Communication development.
(iv) Social or emotional development.
(v) Adaptive development; or
(2) Have a diagnosed physical or mental condition that has a high probability of resulting in developmental delay.
(b) The term may also include, at a State's discretion, children from birth through age two who are at risk of having substantial developmental delays if early intervention services are not provided.

Code of Federal Regulations
Note 1:The phrase “a diagnosed physical or mental condition that has a high probability of resulting in developmental delay,” as used in paragraph (a)(2) of this section, applies to a condition if it typically results in developmental delay. Examples of these conditions include chromosomal abnormalities; genetic or congenital disorders; severe sensory impairments, including hearing and vision; inborn errors of metabolism; disorders reflecting disturbance of the development of the nervous system; congenital infections; disorders secondary to exposure to toxic substances, including fetal alcohol syndrome; and severe attachment disorders.
Code of Federal Regulations
Note 2:With respect to paragraph (b) of this section, children who are at risk may be eligible under this part if a State elects to extend services to that population, even though they have not been identified as disabled.
Under this provision, States have the authority to define who would be “at risk of having substantial developmental delays if early intervention services are not provided.” In defining the “at risk” population, States may include well-known biological and environmental factors that can be identified and that place infants and toddlers “at risk” for developmental delay. Commonly cited factors include low birth weight, respiratory distress as a newborn, lack of oxygen, brain hemorrhage, infection, nutritional deprivation, and a history of abuse or neglect. It should be noted that “at risk” factors do not predict the presence of a barrier to development, but they may indicate children who are at higher risk of developmental delay than children without these problems.
