Heading: Onset before age twenty-two

Text: Hayes also relies on her school records to argue that her poor academic record demonstrates that she had intellectual deficits during her developmental years. For the reasons explained above, her school records prove little. Additionally, this Court has never held that poor academic performance, in and of itself, is sufficient to warrant a finding of onset of subaverage intellectual functioning before age twenty-two. Cf. Foster, 279 F.3d at 355 (“The only evidence in the record pertaining to this issue is that Foster left school after completing ninth grade, but why Foster did not continue her studies is unclear.”). Hayes offers no other evidence to establish onset before age twenty-two, and, without establishing this prong, she cannot equal Listing 12.05. See West v. -8- No. 09-5409 Lisa D. Hayes v. Commissioner of Social Security Comm’r of Soc. Sec., 240 F. App’x 692, 698 (6th Cir. 2007) (affirming, in part, because claimant offered no evidence of onset before age twenty-two).
