What are the physical and mental demands of a claimant’s past relevant work as the claimant performed it?
SSR 82-62 provides that “statements by the claimant regarding past work are generally sufficient for determining the skill level, exertional demands and nonexertional demands of such work.” Therefore, your client’s testimony can establish the skill level of his past work. However a vocational expert is usually asked by the Administrative law judge to describe the claimant’s past work. Such evidence may be helpful in supplement or evaluating the accuracy of the claimant’s description of his past work. 20 C.F.R. Section 404.1560(b)(2).
