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 Slosson-Diagnostic Math Screener (S-DMS) was designed to help identify students in Grades 1 to 8 at risk for mathematics failure. Internal consistency, test-retest reliability, item analysis, decision efficiency, convergent validity, and factorial validity of all five levels of the S-DMS were studied using 20 independent samples of students…

The study investigated the concurrent validity of the Peabody Individual Achievement Test (PIAT) with 60 learning disabled adolescents. Findings generally supported the concurrent validity of the PIAT as a measure of academic achievement with secondary learning disabled students. (SBH)

The content validity of the Peabody Individual Achievement Test and the Wide Range Achievement Test was examined with 27 educationally handicapped students (5-9 years old). (CL)

The article presents a statistical and descriptive comparison, with emphasis on math subtests, of the Wide Range Achievement Test and the Peabody Individual Achievement Test, based on scores obtained from clients (in grades 1-12) at a university-affiliated learning disabilities center. (SBH)

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)

The study was designed to provide a comparison of Peabody Individual Achievement Test (PIAT) and Wide Range Achievement Test (WRAT) scores in 49 learning disabled children (mean age 11 years at initial testing). (SBH)

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)

A study involving 63 third graders revealed that the Wide Range Achievement Test gives higher grade equivalent scores than the Test of Written Spelling and that Canadian and American norms were incongruent. Spelling error analysis suggested that the visual image should be a primary focus for both third-grade and remedial students. (CL)

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 position that intelligence and achievement are essentially different measures of the same construct has often been referred to as a "jangle fallacy." Such a position challenges the present practice of placing children in learning disabilities programs based on a discrepancy between Intelligence Quotient (IQ) and achievement. This…
