The Modified WAIS is an approach for shortening the total administration time of the WAIS by approximately 25%. The Modified WAIS uses the Information subtest as a criterion for raising the point at which initial questioning begins on 5 of the 11 subscales. The Modified WAIS was shown to correlate quite highly with the Standard WAIS: .999 for Verbal, Performance, and Full Scale IQ (N = 200). While the number of cases for which the Modified WAIS is applicable will vary from setting to setting depending on the number of cases that meet the criterion, the Modified WAIS appears to be a viable alternative to short forms.
