The document provides information about disability benefits for children and adults through the Social Security Administration (SSA). It discusses the 3-step process for determining if a child qualifies for SSI disability benefits, including whether they have a severe medically determinable impairment, and whether their impairment meets or equals a listing or functionally equals a listing based on limitations in functional domains. It also reviews common childhood impairments, the growth of the children's SSI program, and factors considered in evaluating medical opinions.
