This study investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test, using the Slosson Intelligence Test For Children and Adults as the predictor. Results indicate that the Slosson IQ significantly predicts Wide Range standard scores. (Author)

Performance of norms group on Reading and Arithmetic subtests of WRAT was compared with that of a representative national sampling. Systematic differences were found between the two data sets, and effects of these differences on current norms were illustrated. Norms tend to underestimate subject's achievement level relative to general population.…

Study investigated efficacy of predicting academic achievement as measured by the WRAT, using Verbal and Performance scores of WISC-R as predictors. Both tests were given to 155 children referred for psychological evaluations. Performance IQ did not significantly predict academic achievement, and Verbal IQ significantly predicted only Reading and…

So as to compare predicted achievement based upon WISC-R IQs and observed achievement by the WRAT standard scores, both instruments were administered by the same school psychologist to 282 urban students referred for psychological evaluation. The correlations obtained were substantial. (Author)

The present study was undertaken with two related goals: (a) to examine the relationships between the WRAT and CAT, and (b) to examine the relationships which may exist between these academic achievement tests -nd a standard intelligence battery such as the Wechsler Scale. (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.…

To determine whether the preponderance of males in classrooms for the learning disabled (LD) constitutes sexual discrimination, an objective index involving the discrepancy between expected and actual achievement was calculated for each student. No evidence was found to indicate sexual bias in diagnostic and placement practices. (Author/ABB)

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)

Investigated capability of WISC-R Verbal Comprehension (VC), Perceptual Organization (PO), and Freedom from Distractibility (FD) factor scores to predict academic achievement as measured by the Wide Range Achievement Test (WRAT). Multivariate multiple regression analysis revealed FD and VC factors predict WRAT reading, spelling, and arithmetic…

A comparison of normative data for the 1976 and 1978 Wide Range Achievement Test (WRAT) showed standard scores are comparable, except on Spelling II, but grade ratings are not comparable at the upper ends of the distributions. (Author)

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. (Author)

The use of regression equations to predict the expected achievement levels of five- and six-year-old children on the Wide Range Achievement Test are discussed. Problems are found in identifying underachievement for children in the lower primary grades. Implications for the early identification of specific learning disabilities are described.…

A comparison of reading subtests of the Wide Range Achievement Test, Peabody Individual Achievement Test, and Slosson Oral Reading Test showed a high correlation between the WRAT and PIAT. Suggests the WRAT and PIAT measure the same dimension of reading achievement, possibly verbal fluency. (Author/JAC)

A study with Mexican-American children showed the internal consistency reliability coefficients for the Wide Range Achievement Test (WRAT) were high and comparable to those reported in the WRAT manual. A high relationship was found between WRAT and Metropolitan Achievement Test scores. WRAT meets reliability and validity requirements with Mexican…

Learning disabled college students (N=16) were tested to compare the Wide Range Achievement Test (WRAT) with the Peabody Individual Achievement Test (PIAT). Significantly different scores are derived when WRAT norms are compared with PIAT norms, indicating that the tests are not interchangeable instruments for academic achievement. (RC)
