What is a requirement for an individual to qualify for SSI disability?

To qualify for Supplemental Security Income (SSI) disability benefits, an individual must not be able to engage in any substantial gainful activity (SGA) due to a medical condition that is expected to last for at least 12 months or result in death. This requirement focuses on the individual's functional limitations and ability to work, rather than their educational background, age, or part-time work availability.

The criterion of being unable to perform substantial work reflects the program's goal of providing assistance to those who are genuinely disabled and unable to support themselves through employment. While some individuals with disabilities may be able to work at a limited capacity, those qualifying for SSI need to demonstrate a significant impairment that prevents them from engaging in any meaningful work.

The options mentioning work capabilities, education, or age do not align with the fundamental eligibility criteria set forth by the Social Security Administration for SSI disability benefits, making the requirement of not being able to do any substantial work the key factor for qualification.
