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 =…

The Working Memory Rating Scale (WMRS) was designed as a behavioral rating tool to assist teachers in identifying students at risk of working memory difficulties. The instrument was originally normed on 417 monolingual English-speaking children from the United Kingdom. The purpose of this study was to test the reliability and validity of the WMRS…

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)

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…

Background: The marked degree of heterogeneity in persons with developmental dyslexia has motivated the investigation of possible subtypes. Attempts have proceeded both from theoretical models of reading and the application of unsupervised learning (clustering) methods. Previous cluster analyses of data obtained from persons with reading…

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)

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…

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…

When administered to 87 boys and 53 girls in screening procedures, significant score correlations between Quick Test and Wechsler Intelligence Scale for Children-Revised intelligence quotients and between the Wide Range Achievement Test Reading scores indicated that Quick Test is an effective tool for making valid brief estimates of intelligence.…

Investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test using the factor scores of the Wechsler Intelligence Scale for Children-Revised as potential predictors. Results indicated that the freedom from distractibility factor score significantly aided in the prediction of reading and spelling…

Although Verbal IQ of the Wechsler Intelligence Scale for Children predicts statistically distinct Wide Range Achievement Test Reading scores dependent on the sex of the child, the differences are of little practical importance. (Author)

Comparison of intelligence and achievement test scores of male and female deaf and hard-of-hearing school-age children found that boys scored almost a full standard deviation higher than girls on performance subtests of both the Wechsler Intelligence Scale for Children III and Revised scales. There were no mean differences between boys and girls…
