The purpose of this part is to provide financial assistance to States to—

(a) Develop and implement a statewide, comprehensive, coordinated, multidisciplinary, interagency system that provides early intervention services for infants and toddlers with disabilities and their families;

(b) Facilitate the coordination of payment for early intervention services from Federal, State, local, and private sources (including public and private insurance coverage);

(c) Enhance State capacity to provide quality early intervention services and expand and improve existing early intervention services being provided to infants and toddlers with disabilities and their families;

(d) Enhance the capacity of State and local agencies and service providers to identify, evaluate, and meet the needs of all children, including historically underrepresented populations, particularly minority, low-income, inner-city, and rural children, and infants and toddlers in foster care; and

(e) Encourage States to expand opportunities for children under three years of age who would be at risk of having substantial developmental delay if they did not receive early intervention services.
