The purpose of this study is to construct and evaluate diagnostic battery tests of verbal and non-verbal learning disabilities for students in the Arabic schools. 612 students were in the 3rd, 4th and 5th grades of primary school were involved, mostly from Egypt and Saudi Arabia. Their ages ranged from 7.94-10.98 with mean age = 9.62 and SD =…

This study assessed trait validity of the Reynolds Intellectual Assessment Scales' (RIAS) Verbal Index (VIX) and Nonverbal Index (NIX) scores in a group of college students. Using both observation of patterns and latent variable modeling of a multitrait-multimethod correlation/covariance matrix, the results indicate that the RIAS VIX scores…

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)

Thirty elementary students referred for possible learning disability were administered the achievement sections of the Woodcock-Johnson Psycho-Educational Battery and several traditionally used school district tests. Identical student placement decisions were reached on 23 out of 30 students. (Author/GDC)

Forty trainable mentally retarded students were concurrently administered the Stanford Scale and the Wide Range Achievement Test (WRAT). WRAT reading, spelling and arithmetic subtests were regressed on Stanford intelligence quotients. Predictions were statistically valid. Derived regression equations are reported. (Author/CP)

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 Perkins-Binet Test of Intelligence for the Blind, Form U; the Wechsler Intelligence Scale for Children-Revised (WISC-R), Verbal Scale; and the Wide Range Achievement Test (WRAT) were administered to 52 low-vision children in the third, fifth, seventh, and ninth grades. Results indicated that the mean ten scores on the two tests of intelligence…

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)

This study investigated the differential validity of the Wide Range Intelligence Test, which is a new, brief measure of ability. Participants (N = 744) ranged in age from 5 through 85 years (M = 26.7 years, SD = 21.4 years) and varied by the demographic variables of gender, race/ethnicity (Anglo, African American, Hispanic), and education level…

Compared regression lines for prediction of Wide Range Achievement Test scores by Wechsler Intelligence Scale for Children and revised WISC Full Scale IQs across race. Results support the use of a common regression line in the prediction of achievement scores for races. (Author)

Evaluated relation of performance on the Stanford-Binet Intelligence Scale: Fourth Edition to performance on the Wide Range Achievement Test-Revised and Woodcock-Johnson Psychoeducational Battery: Tests of Achievement for 31 normal, elementary-aged students using both the area score and Sattler's factor score approaches. (Author/ABL)

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…

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)

The Wechsler Intelligence Scale for Children-Revised Full Scale IQ did not yield valid predictions of achievement of educable mentally handicapped students in a public school setting, as measured by the Wide Range Achievement Test (WRAT). (Author/CM)

Investigates the WISC-II and WRAT3 test scores of 37 children in a rural Arkansas school district who were referred for evaluation because of academic difficulties. Results indicate that the WRAT3 correlations with the WISC-II ranged from between 0.42 and 0.66. These findings are consistent with others on the general correlations between IQ and…
