Determine about the National Adult Reading Test

The National Adult Reading Test (NART; Nelson, 1982) allows the researcher to obtain an estimate of an individual's IQ prior to damage or disease onset. This may be useful if a neuropsychologist is making an initial assessment of a person who has been brain damaged or ill for some time. The NART comprises 50 words that sound different to their spelling (such as yacht, ache and thought). The respondent reads through the list until they begin to make pronunciation errors. Such words were almost certainly learned before the onset of illness or brain damage, and because this test has been referenced against the WAIS, the cut off point can be used to estimate IQ prior to illness, disease or accident
