By working, an individual may demonstrate the ability to engage in SGA, at least for
the time worked. However, a finding that work was not SGA during a particular period
does not answer the ultimate question of ability to engage in SGA. To answer this
question, the DDS must consider all the medical and vocational evidence, of which
the work performed after alleged onset of disability is only a part. In some cases,
the complete evidence may show that (1) the individual's impairment is less severe
than alleged or (2) the person has the physical, mental and vocational qualifications
necessary for SGA. Other instructions furnish guides on how to evaluate the total
spectrum of medical and vocational evidence for this purpose.
