Comparisons were made between the PPVT-R and WISC-R with 59 school-aged students (25 females, 34 males) referred for academic underachievement. Pearson product moments (r) and related t-tests were employed in the data analysis. The sample ranged in age from 6-2 to 15-5, with a mean age of 10-1, and SD=2.8. There were no significant differences between PPVT-R standard scores and WISC-R IQs. PPVT-R scores correlated significantly (p<.001) with WISC-R Verbal subtest scores. Implications of these findings for the use of the PPVT-R are discussed.
