Validation research for educational achievement tests is often limited to an examination of intended test score interpretations. This article calls for an expansion of validation research in three dimensions. First, validation must attend to actual test use and its consequences, not just score meaning. Second, validation must attend to unintended…

Paper discusses advantages and disadvantages of using the Leiter International Performance Scale with autistic children and presents the results of a study comparing the performance of 18 autistic children on the Wechsler Intelligence Scale for Children-Revised and the Leiter. Results showed a high positive correlation between the WISC-R…

For mildly and moderately mentally retarded individuals, the Wechsler Adult Intelligence Scale-Revised measures at about the same level as the Wechsler Adult Intelligence Scale, and, consequently, it also produces much higher IQs than the Wechsler children's scales or the Stanford-Binet Intelligence Scale, Form L-M, despite high intertest…

Validity of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) intersubtest scatter as an indicator of cognitive impairment due to brain dysfunction was studied with 316 brain-damaged men. When compared with the WAIS-R standardization sample, intersubtest scatter was not greater for normal persons of similar intelligence quotient. (SLD)

Two studies involving 89 children were conducted to evaluate the validity of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) with African American students undergoing special education evaluations. Results were highly correlated with previously determined IQs, and the factor structure of the WISC-III was generally supported.…

The Wechsler Intelligence Scale for Children-Third Edition (WISC-III) is an individually administered test of intelligence for assessing children aged 6 through 16 years, 11 months. The WISC-III consists of several subtests, each classified into a verbal or performance scale. The child's performance on these measures is summarized in three…

Intelligence quotient profiles in 81 high-functioning children and adults with autism were examined. Profiles did not reveal the presumed typical pattern of a lower verbal IQ than performance IQ. Results found that individuals with autism demonstrated a wide range of ability levels and patterns on the Wechsler Intelligence Scales, without a single…

The concurrent validities of 3 short forms of the Wechsler Adult Intelligence Scale (WAIS) were compared for their prediction of full-scale IQ for 145 male and 159 female psychiatric inpatients. Results support previous research showing better predictive accuracy for L. C. Ward's (1990) seven-subtest short form than the others. (SLD)

The reliability and validity of three short forms of the Wechsler Intelligence Scale for Children III (WISC-III) were compared. Each of the short forms was a tetrad composed of two verbal and two performance subtests. The first tetrad was selected based primarily on practical considerations, particularly its brevity to administer and score. The…
