If a child has a severe impairment(s) that does not meet or medically equal any listing, the Social Security Administration (SSA) will then look to see if the child functionally equals the listings. To functionally equal the listing, the child’s impairments must result in marked limitations in two domains, or extreme limitation in one domain.
The first domain used by SSA is called 1. Acquiring and using information. In this domain SSA considers how well the child acquires or learn information, and how well you use the information the child has learned. Children learn through life experiences growing up. Using the concepts they have acquired through play and experiences, they should be able to learn to read, write, do math, and understand and use new information.
Thinking is the application or use of information that the child has learned. This includes perceiving relationships, reasons, and making logical choices. The child must also be able to use language to think about the world and understand others. SSA will consider all of the relevant information in the case record when deciding whether the child’s medically determinable impairment(s) result in marked or extreme limitations in this domain.
