Investigated factor structures of Wechsler Intelligence Scale for Children-Revised (WISC-R) and Kaufman Assessment Battery for Children (K-ABC) for 212 normal children. Findings suggest correspondence between: (1) WISC-R Verbal Comprehension and K-ABC Achievement; (2) WISC-R Perceptual Organization and K-ABC Simultaneous Processing; and (3) WISC-R…

Although authors have varied opinions, it is the general concensus that the WISC-R is superior to the WISC. This author concurs. However, serious consideration should be given to the research findings before the WISC-R is substituted freely for the WISC as a criterion for special education placement. (Author)

The results of the present study suggested that PPVT and SIT IQs are not directly comparable to the WISC-R IQs when the moderate to low correlation coefficents are considered. In addition, the SIT appears to be more comparable to the WISC-R than does either Form A or Form B of the PPVT. (Author)

Because WISC users will inevitably need to shift from the WISC to the WISC-R, further research is needed to demonstrate the comparability of these two forms (and norms) of basically the same test. The present study provides data on EMR child children in the 12-1/2 to 14-1/2 year age range. (Author)

Error in assessing learning aptitude inheres much more in the users of the tests than in the tests themselves. Assumptions fundamental to such assessment are considered. It is particularly important that the tester constantly be sensitive to the nature of the relaionship between the psychological demands of test items or tests and the learning…

The present study examined the reliability of the WISC-R subtests and IQ scales when administered to Mexican-American children. In an effort to extrapolate these findings to the individual child, this study also attempted to ascertain the standard errors of measurement for each subtest and IQ scale. (Author)

The data suggest that the WISC-R Verbal, Performance, and Full scales are almost equally lacking in racial bias and that all three scales are less biased than the PPVT. If the PPVT is used for initial screening, it will be important to follow up with a more thorough psychological evaluation. (Author)
