✦ Synopsis

In addition, in the Hamm. et al., study when the WISC-R was administered first the differences between the WISC and WISC-R scores were highly significant ( p < .001). When the WISC was administered first, however, the differences were not as significant ( p < .01 and p < .02). In the present research, all subjects were given the WISC first. Also, their research grouped the children homogeneously by age within groups with the youngest subject being 9-6. I n contrast, our sample included children ranging in age froni 6-12 years a t the time they were administered the WISC.

Results of this present. research show the WISC-R to be a valid instrument for classifying children as ERIR. This finding should be most reliable for EMR children who are similar in geographic and educational background to the ones used in this study. Due to the differential findings of the Hamm, et al., study and the present one, however, and the importance of this issue, a large scale research project is needed which would include the youngest school-aged children, with consideration given to geographic region and the effect of test-retest interval.
