The ability of the National Adult Reading Test (NART; Nelson & Willison, 1991) and the revised NART (NART‐R; Crawford, 1990) to estimate IQ was examined in a healthy sample ( N = 47) using the Wechsler Adult Intelligence Scale‐Revised (WAIS‐R) scores as the criterion. Mean estimated IQs from the NART‐R were not significantly different from the WAIS‐R Full Scale and Performance IQ, but the NART‐R significantly overestimated Verbal IQ by 2.5 points. Nelson & Willison's (1991) NART equations significantly overestimated Full Scale and Verbal IQ by 5.3 and 5.5 IQ points respectively. The NART‐R had significantly higher correlations with Full Scale and Verbal IQ than the NART.
