Early intervention services, also known as the Program for Infants and Toddlers with Disabilities, provide services for infants and toddlers with disabilities and their families. In some states, eligibility extends to those who are at risk for developing a disability. States’ eligibility criteria for early intervention services vary, as do the services they offer.
The numerator is the cumulative number of infants and toddlers with disabilities ages 0-2 who received early intervention services under IDEA, Part C during the most recent 12-month period for which data are available. The denominator is the number of children ages 0-2 in the population.
