The present investigation compared the PPVT‐R/WISC‐R scores of a “normal” or “nonexceptional population,” as well as whether prior administration of either of these instruments affected scores on the other. Forty public school second‐grade students served as subjects and were randomly assigned to one of four groups, with the order of test administrations determined by group assignment: WISC‐R/PPVT‐R (Form L): WISC‐R/PPVT‐R (Form M); PPVT‐R (Form L)/WISC‐R; PPVT‐R (Form M)/WISC‐R. The results indecate that, as with exceptional populations, normal school children tend to score lower on the PPVT‐R than on the WISC‐R. Scores from these two tests are moderately correlated, and prior adminstration of one of the instruments does not appear to alter scores on the other. Implications for practice are discussed.
