Written-expression curriculum-based measurement (WE-CBM) is used for screening and progress monitoring students with or at risk of learning disabilities (LD) for academic supports; however, WE-CBM has limitations in technical adequacy, construct representation, and scoring feasibility as grade-level increases. The purpose of this study was to…

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 purpose of this article is to describe preliminary psychometric characteristics of a student self-report measure of self-determination, the "Self-Determination Inventory: Student Report" version (SDI-SR), designed for youth with and without disabilities. We administered the draft assessment to 311 youth and examined item functioning…

The Ability-Achievement Model is reviewed for efficacy in comparison to the Response to Intervention Model when diagnosing students with possible learning disabilities. The research will address the success of Ability-Achievement Model versus the Response to Intervention Model when successfully diagnosing students with learning disabilities was…

This study compared the test-retest reliability of the Southern California Sensory Integration Tests and the Luria-Nebraska Neuropsychological Battery--Children's Version. Both sets were administered twice to a group of 30 dysfunctional eight-year-old children. Findings are discussed in relation to reliability coefficients for normal as well as…

This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…

This article provides the equations necessary to derive a single composite score based on two achievement scores measuring the same discrepancy area in students with learning disabilities. Also provided are the equations necessary to determine the composite score's reliability and its correlation with an IQ score. (CR)

This comparison of regression discrepancy model results for learning disability identification used published IQ-achievement and reliability coefficients and generic, mean values. Use of mean IQ-achievement values resulted in higher discrepancy rates for a clinical sample. Use of both mean IQ-achievement and reliability values resulted in higher…

Educators designing procedures for identifying students as learning disabled are faced with serious technical difficulties. A student with a learning disability is one who "has a severe discrepancey between achievement and intellectual ability" in one or more designated areas. The methods of quantifying achievement, intellectual ability,…
