This study is a concurrent validation of Level II of the Wide Range Achievement Test-Revised (WRAT-R) using the Wechsler Adult Intelligence Scale (WAIS) Verbal, Performance, and Full Scale IQ scores as criterion measures. Forty-five subjects were administered the WAIS-R and WRAT-R and their scores correlated. (Author/LMO)

A comparison of the Wide Range Achievement Test (WRAT) and the Peabody Individual Achievement Test (PIAT) indicates that the two should be used interchangeably only with caution and understanding of the differences. While there is a moderate to high correlation between the test scores, nevertheless, the two have distinctly different strengths and…

Relationships between the McCarthy General Cognitive Index and WISC-R Full Scale IQ with the Wide Range Achievement reading scores were explored with a sample of 20 educable mentally retarded and 20 learning disabled children, ages six to nine. (Author/SJL)

Investigated the concurrent validity of the Wechsler Intelligence Scale for Children (Revised) subtests and three IQs compared to Wide Range Achievement Test standard scores, in 28 learning-disabled children. Analysis showed no significant correlations between WISC-R and WRAT scores, indicating a lack of concurrent validity on the WAIS-R. (WAS)

Demonstrates the need for schools to clearly define diagnostic categories such as learning disabilities (LD). These LD students were considerably different from LD students in other studies. They performed on grade level according to the Wide Range Achievement Test, but significantly below their peers in actual classroom performance. (Author)

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)

Though some unexpected sex differences were discovered, the two diagnostic categories were not found to be psychometrically distinct. Further, the results of a longitudinal analysis suggested that, while IQ scores remained relatively stable over time within a subset of the original sample, achievement scores definitely declined.

The investigation examined the "Wide Range Achievement Test" (WRAT) and its subtests (spelling, reading, and arithmetic), as well as possible differences attributable to the factors of sex, with the "Chicago Non-Verbal" (CNV) as a criterion variable. The 1970 study encompassed 72 Indian students (with a mean chronological age…

Regression lines for the prediction of Wide Range Achievement Test (WRAT) scores by Wechsler Intelligence Scale for Children (WISC) and WISC Revised (WISC-R) intelligence quotients were compared across race, by the Potoff technique. Subjects were 36 black and 30 white children who were referred for psychological evaluation because of learning or…

Examines differences between 45 learning disabled, mentally retarded, and Title I elementary students on intelligence, academic achievement, and behavior measures. Indicates that such students perform similarly on academic achievement and behavior measures. Learning disabled and Title I students were similar on an intelligence measure; mentally…
