The level of difficulty of each item of the Vocabulary scale of the WAIS—R was calculated for a British population. Discrepancies were shown between these and those in the US standardization that result in 14 per cent of British subjects recording correct answers beyond the official criterion for discontinuing the test. If these are ignored, the performance of 4 per cent of such subjects is undervalued by as much as two scaled score points. In order to minimize this it is suggested that the test be discontinued only after six consecutive failures.
