This study compared the WISC‐R and PPVT scores for a group of 65 students classified as mentally retarded, ranging in age from 7.5 to 14.5. Pearson product moments (r) and correlated t values were employed in the analysis of data. The evidence from the present study indicated that for this sample of mildly retarded children and youth, the PPVT IQ score is significantly higher than the Full Scale IQ from the WISC‐R. The current findings indicate that the same general pattern exists for the WISC‐R and PPVT as for the WISC and PPVT scores.
