Conducted study to examine whether practitioners err in administering and scoring Wechsler Adult Intelligence Scale-Revised (WAIS-R). Obtained WAIS-R protocols from 50 randomly selected psychological folders in records of 1 school district. Found that practitioners committed errors on all 50 protocols. Errors on 27 of 50 protocols were sufficient…

Analyzed 56 Wechsler Intelligence Scale for Children-Revised protocols completed by 1 certified and 8 licensed practitioners to examine administration and scoring mistakes. Observed numerous mistakes (failure to record examinee responses, assigning too few or too many points to answers, inappropriate questioning, and failure to obtain correct…

Investigated specific problem caused by traditional method of teaching students to administer Wechsler Adult Intelligence Scale-Revised. Analysis of 180 protocols by 26 graduate students revealed average of 8.8 mistakes per protocol. When errors were corrected, 81 percent of Full Scale intelligence quotients were changed. Students' performance…

This study, involving 64 students with specific learning disabilities, found positive correlations between the Wechsler Intelligence Scale for Children-III (WISC-III) and the Arithmetic subtest of the Wide Range Achievement Test-Revised (WRAT-R), the KeyMath-Revised, and the Peabody Picture Vocabulary Test-Revised, but not between the WISC-III and…

Investigated most frequent types of examiner errors made by graduate students (n=26) in administering Wechsler Intelligence Scale for Children-Revised (WISC-R) and examined on which items these mistakes were most likely to occur. Findings identified deficiencies in traditional methods of teaching students how to administer the WISC-R. Students…

Scores of 38 learning-disabled college students on the revised Wechsler Adult Intelligence Scale (WAIS-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) were compared. Results indicated significant correlations between the tests, though subjects tended to obtain higher scores on the WISC-R than on the WAIS-R. (Author/DB)

Investigation of the stability of Wechsler Adult Intelligence Scale Revised scores of 25 college students over a 4-year period found that global and subtest scores were highly stable. Subtest scores tended to be higher on the retest, but global scores were not despite four years of educational experiences between test administrations. (Author/DB)

This study, involving 47 deaf and hard-of-hearing school-age children, found that the Wechsler Intelligence Scale for Children-Third Edition Performance scale was highly related to the WISC-Revised Performance scale and moderately related to the Wide Range Achievement Test-Revised subscales. Performance IQs of students who communicated orally or…

Discrepancies between IQ and Index scores on the WISC-III were investigated for a sample of students with Specific Learning Disability (SLD) and with mental retardation and evaluated but not classified. Consistent with the WISC-R literature, the discrepancies between Verbal and Performance IQs and higher Performance than Verbal IQs (which…

WISC-III scores of 233 students (ages 9 to 13) with mental retardation were examined. Boys had higher Full Scale, Verbal, and Performance IQs than did girls. Boys also had higher scores on six of the 10 subtests. In addition, all of the statistically significant differences were in favor of boys. (Author/CR)

Comparison of Wechsler Intelligence Scale for Children (WISC)-Revised and WISC III IQs for 64 students with specific learning disabilities and 55 students with mental retardation (MR) found that correlations were lower than those reported in the WISC-III manual. Only Performance IQs for students with MR matched the correlations reported in the…

Studies have revealed significant problems in correctly scoring ambiguous verbal responses to test items on the Wechsler Intelligence Scale for Children-Revised (WISC-R). This study evaluated the effectiveness of an instructional design procedure developed to reduce examiner scoring errors on the WISC-R. Data concerning frequent sources of error…

Clinical psychology graduate students (N=14) administered Wechsler Intelligence Scale for Children-Revised. Found numerous scoring and mechanical errors that influenced full-scale intelligence quotient scores on two-thirds of protocols. Particularly prone to error were Verbal subtests of Vocabulary, Comprehension, and Similarities. Noted specific…

Investigated correlations between two intelligence measures for exceptional children. Corrected correlations between the tests indicated differences with correlations reported in one manual. Relationships were generally higher than those reported elsewhere. Implications are discussed, especially those involving the use of correlations between…

The Wechsler Intelligence Scale for Children III (WISC-III) Intelligence Quotients (IQs) of 49 students (ages 7-16) referred for a three-year reevaluation were analyzed. Correlations of WISC-III IQs to WISC-III IQs three years previously were high for the Full Scale, Verbal, and Performance IQs. Even so, IQs dropped a statistically significant…
