To receive accommodations, you would need a neuropsychological evaluation. The neuropsychological evaluations are eight hours long, intensive, and consist of many tests (memory, IQ, executive functioning, processing speed). Aside from tests of cognitive and academic performance, these evaluations include clinical interviews with clients and families. All the information gathered is utilized to provide an in-depth overview of your cognitive strengths and weakness. The neuropsychological testing culminates in a 25-page report, which you can use to seek accommodations.
The Sachs Center provides both diagnostic and neuropsychological evaluations.
