Correlations of WPPSI IQs with concurrently administered subtests from the WRAT were compared with analogous WISC‐R/WRAT correlations in a group of children referred by regular classroom teachers for school psychological services. Although the magnitudes of all correlations were reduced, due to restriction of range, the comparisons indicated no significant differences in the magnitudes of the correlations of the WPPSI and the WISC‐R with the WRAT. These results support the use of the two instruments as equivalent predictors of achievement.
