This article briefly reviews the history of intellectual assessment of children and youth in the United States of America, as well as current practices and future directions. Although administration of intelligence tests in the schools has been a longstanding practice in the United States, their use has also elicited sharp controversy over time.…

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…

Data on the magnitude of significant Wechsler Intelligence Scale for Children-Revised Verbal-Performance Intelligence Quotient (IQ) discrepancies (specifically the nondirectional aspect of significant frequencies) within the normal population are often misunderstood by clinicians. Suggestions for remedying inaccuracies in reporting discrepancies…

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…

The Wechsler Intelligence Scale for Children (WISC) has a long history, dating back to the 1930s, when it was devised specifically for measuring the intelligence of children through verbal and performance subtests. Intelligence quotients (IQs) are developed for verbal and performance skills. The subtests, their factors, indices derived from them,…

Scores on the Wechsler Adult Intelligence Scale (WAIS) were compared with reevaluation scores obtained four years later on the WAIS-Revised for a group of 108 mildly and moderately retarded adults. The moderately retarded subgroups (N=22) demonstrated significantly higher WAIS-R intelligence quotients. Implications for use of the WAIS-R are…
