โฆ Synopsis
WISC-III IQ score changes, for a group of 70 educable mentally handicapped students, over a 3-year period were found to be significantly lower for VIQ, Information, and Vocabulary tests. Trait stability (based on an average 3-year retest interval) in intelligence measurement, as represented by the WISC-III FSIQ, VIQ, and PIQ, was considerably lower-as expected-than reported for the standardization sample (based on a 23 day retest interval) in the WISC-III manual. Significant individual variation was observed, with the FSIQ showing a 22 point range difference and the VIQ and PIQ showing even larger ranges between the first and second testing. Implications regarding profile analysis and program planning for EMH students are presented.
