They'll probably do a full battery of neuropsychologial testing, inluding things like an IQ test, the Wechsler Memory Scale (which includes language memory, visual memory, tapping blocks, recalling stories), attention testing, problem solving testing, and maybe the MMPI (a personality test). If you request, they may do the ADOS or if you have a family member present, the ADI-R to test for an ASD. The ADOS is really the gold standard of autism testing, so if you want to be tested for AS, I recommend requesting that they do it.
