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 =…

As a result of the upcoming Federal reauthorization of the Individuals With Disabilities Education Improvement Act (IDEA), practitioners and researchers have begun vigorously debating what constitutes evidence-based assessment for the identification of specific learning disability (SLD). This debate has resulted in strong support for a method that…

Published by the Canadian Test Centre (CTC), "Insight" represents a group-administered test of cognitive functioning that has been built entirely upon the Cattell-Horn-Carroll (CHC) theoretical framework. "Insight" is intended to be administered by educators and screen entire classrooms for students who present learning…

The Wechsler Intelligence Test for Children -- Fifth Edition (WISC-V) is a comprehensive intellectual ability assessment for children. The WISC-V was developed over the course of five years by an expert team including doctoral-level scientists and clinicians and an advisory panel, who provided expert advice about intellectual ability testing,…

Whenever a major intelligence or achievement test is revised, there is always renewed interest in the underlying structure of the test as well as a renewed interest in the scoring, administration, and interpretation changes. In this interview, Amy Gabel discusses the most recent revision of the "Wechsler Intelligence Scale for Children-Fifth…

Compared Wechsler Intelligence Scale for Children-Revised (WISC-R) tests and retest scores for 322 learning disabled children over three years for factor structure and structure stability. Results suggest that WISC-R factor structure was stable over three years. Coefficients of congruence indicated factorial similarity between groups of Black and…

Examined records of 170 learning-disabled students to determine stability of Wechsler Intelligence Scale for Children-Revised (WISC-R) test scores. WISC-R was readministered three years later to 150 subjects. Stability coefficients were .72, .70, and .74 for Verbal, Performance, and Full Scale Intelligence Quotient scores. Results suggest WISC-R…

Examined temporal stability of Wechsler Intelligence Scale for Children-Revised (WISC-R) for adolescents (N=155) identified as either educable mentally retarded (EMR) or learning disabled (LD). Found three major scales of WISC-R to be more stable over three-year period for LD than for EMR group, while subtest scales for EMR group showed greater…

Examined Wechsler Intelligence Scale for Children-Revised (WISC-R) scores of 100 learning-disabled and 60 mildly retarded children retested on 3 separate occasions at 3-year intervals. Different results were obtained depending upon criterion considered. (Author/ABL)

Compared Kaufman Assessment Battery for Children (K-ABC) with Wechsler Intelligence Scale for Children-Revised (WISC-R) and Peabody Individual Achievement Test (PIAT) to determine K-ABC's utility in determination of a severe discrepancy for learning disabilities classification. Found that K-ABC and WISC-R/PIAT approaches to the determination of a…

Stability of the WISC-R subtest profile for 161 learning disabled (LD) children over a 7-month test-retest interval was examined. A unique subtest profile reported earlier was replicated. Performance IQ was significantly greater than Verbal IQ at both testing occasions. (Author)

Although differences in composite Wechsler Intelligence Scale for Children--Revised (WISC-R) measures were exhibited by children with mental retardation, learning disabilities, and psychological or behavioral disorders, few significant group differences were exhibited. Caution is necessary in making diagnostic statements based on WISC-R profile…

This study examined effects on 62 elementary students with learning disabilities undergoing triennial reevaluation of the change from the Wechsler Intelligence Scale for Children--Revised to the Wechsler Intelligence Scale for Children--Third Edition. Results indicate changes in the correlation with Woodcock-Johnson--Revised Tests of Achievement…

Compared the subtest and IQ scores obtained by learning disabled and retarded children and youth on the Wechsler Intelligence Scale for Children (Revised) after a two-year time interval. Stability coefficients were obtained. The evidence indicated the WISC-R provides stable full-scale IQs. (Author)

Among the findings was that the factor structure of learning disabled children on the Wechsler Intelligence Scale for Children-Revised was somewhat more fractionated and complex than for normals, but not as complex as for reading disabled children. (Author/DLS)
