Accuracy of the Wechsler Test of Adult Reading (WTAR) and National Adult Reading Test (NART) when estimating IQ in a healthy Australian sample

Abstract

The recently published Wechsler Test of Adult Reading (WTAR) has been co-normed with the third editions of the Wechsler Adult Intelligence and Memory Scales (WAIS-III, WMS-III), and has been shown to reliably estimate intelligence in U.S. and U.K. samples. However, the suitability of the WTAR for use in Australia has not been established, nor is there any clear basis for determining whether to use U.S. or U.K. norms to convert WTAR raw scores to obtain estimates of IQ. This study examined the accuracy with which both the WTAR and the National Adult Reading Test (NART) estimated concurrent WAIS-III IQ performance in a sample of 93 healthy Australian adults who completed all three measures.
