Abstract
Slosson Intelligence Test IQs (revised norms) and Peabody Picture Vocabulary Test—Revised (PPVT-R, Form L) standard scores for 100 black rural Headstart children were correlated and then compared by use of a one-way design for repeated measures. Although the correlation of .48 between the two tests was significant, Slosson IQs ( M = 100.27, SD = 14.82) were significantly higher than PPVT-R scores ( M = 74.80, SD = 14.23). These results suggest that the two instruments are not equivalent. There is a need for further research with these two instruments with black and with white children.
