The interpretation of subtest profiles from intelligence testing remains popular among many practitioners who use subtest performance to draw diagnostic conclusions, in spite of criticism by some researchers, who point to the low reliability and predictive validity of subtest scores in predicting achievement outcomes. Prior research outlines two…

The findings suggest that objective tests of motivation add considerably to the prediction of achievement. (Author)

First graders (N=26) completed the Wechsler Intelligence Scale for Children-Revised, McCarthy Scales, and Woodcock-Johnson Scales of Cognitive Ability. Two years later, their academic achievement was determined by Wide Range Achievement Test and teacher ratings. Results suggest that all three intellectual measures are appropriate for predicting…

Examined the Wechsler Scales as predictors of academic achievement for a sample of Native Americans (N=75) from the Columbia Basin area. Results indicated significant Verbal-Performance discrepancies with mean Verbal scores significantly below the normative mean and Performance scores at or above the normative mean. (LLL)

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)

Investigated possible bias of Kaufman Assessment Battery for Children (K-ABC) with 76 White and 90 Mexican-American fifth- and sixth-graders. Criterion variable was Comprehensive Tests of Basic Skills (CTBS). Results showed considerable evidence of bias in differential predictive validity, indicating global cognitive score of K-ABC was less…

Examined the efficacy of the McCarthy Scales as a predictor of reading readiness and achievement in a kindergarten sample (N=33). Results confirmed the predictive validity of the McCarthy Scales and suggested that, for this sample, visual discrimination and sequential ability skills may have been more important factors than verbal abilities.…

Analyzed summed scores of the Wechsler Intelligence Scale for Children (Revised) dyad, vocabulary, and Block Design, cross-tabulated with full scale scores of children (N=249) referred to a gifted program. Results indicated the Vocabulary-Block Design dyad could be useful in predicting full scale IQ for some children. (Author/JAC)

Significant differences were found between the Peabody Picture Vocabulary Test-Revised mean standard scores and Verbal, Performance, and Full Scale IQs. The PPVT-R did not correlate significantly with the WISC-R scales or subtests, suggesting the tests are measuring different abilities. (Author)

WISC-R (Wechsler Intelligence Scale in Children-Revised) Verbal and Performance scores were correlated with WRAT-R Wide Range Achievement Test-Revised scores. The verbal score was found to predict reading, spelling, and arithmetic. The performance score did not add significantly to the predictions. Results were consistent with earlier studies.…

Evaluated a short form of the Wechsler Intelligence Scale for Children-Revised (California Abbreviated WISC for the Intellectually Gifted) for screening gifted referrals. Results indicated the short form could be effective in predicting full-scale intelligence quotient even when the prediction was based on data from the original WISC. (Author/JAC)

Results indicate that the Wechsler Intelligence Scale for Children (Revised) is a valid predictor of achievement for children referred for learning disabilities. The verbal Scale IQ, and the Freedom from Distractibility IQ proved especially useful predictors of academic achievement. (JAC)

The Wechsler Intelligence Scale for Children-Revised (WISC-R) Comprehension, Arithmetic, and Object Assembly and McCarthy Quantitative and Memory Indices were most sensitive to learning disabled students' achievement. Conversely, the WISC-R Similarities and Arithmetic and the McCarthy Verbal Index were most sensitive to achievement of nonlearning…

All variables except the Slosson Intelligence Test were poor predictors of Wechsler Intelligence Scale for Children (Revised) intelligence scores. A moderate correlation was found between verbal and full scale IQ scores and a lower relationship between performance IQ scores on the two scales. Results may be culture specific. (Author/JAC)

Compares the predictive and concurrent validities of a learning efficiency test with that of another test. Memory factor scores of the learning efficiency test correlated significantly with the other test's scores, with class grades, and with actual grade-level functioning in reading. The learning efficiency test's validity compares favorably to…
