The paper reviews Wechsler Intelligence Scale for Children-Revised research that has particular pertinence for the assessment of learning disabilities (LD). Three topics are treated in-depth: factor analysis investigations, recategorization of subtests into Bannatyne's four groupings, and interscale/intrascale scatter. (Author)

The author discusses the regression discrepancy method for identifying learning disabled (LD) children and compares it with other identification techniques, pointing out its advantages but indicating that it is still inadequate as a sole criterion for LD identification. (Author)

The purpose of this article is to offer insights into the complex area of learning disabilities, to provide tips on how to recognize children with various types of learning disabilities, and to offer suggestions for teaching students who are learning disabled. The hope is that with some information and "teaching tips" in this area, more and more…

Reading difficulties and disabilities present serious and potentially lifelong challenges. Children who do not read well are more likely to be retained a grade in school, drop out of high school, become a teen parent, or enter the juvenile justice system. Building on the extant research and seminal studies, including the National Reading Panel and…

There is great controversy in the field of learning disabilities (LD) regarding the establishment of criteria for LD identification. The traditional approach to LD identification is to use the IQ-discrepancy. Lyon and colleagues (2001) point out the numerous problems with such an approach, including faulty assumptions about the adequacy of an IQ…

Identifying Specific Learning Disability (SLD) has been an arduous task. Until IDEA 2004, diagnosing SLD was limited to IQ discrepancy models lacking in both empirical evidence and contributing to minority over-representation. This paper examines the history of SLD assessment, the phenomena of minority over-representation, and the implementation…

Response to intervention (RTI) is a framework for providing high-quality instruction and intervention matched to students' individual needs. It includes the practice of frequent progress monitoring and use of data to make educational decisions about instructional and grouping practices as well as the duration, frequency, and amount of time…

By 2010 it is predicted that one in 900 adults will be survivors of some form of pediatric cancer. The numbers are somewhat lower for survivors of brain tumors, though their numbers are increasing. Schools mistakenly believe that these children easily fit pre-existing categories of disability. Though these students share some of the…

A study investigated the possible relationship between month and season of birth and subsequent identification of learning disabilities in 583 learning disabled and 7,911 non-learning disabled kindergarten through twelfth grade students. Non-parametric statistical analysis of the data indicated non-significant differences in birthdate patterns…

The position statement of the Board of Trustees of the Council for Learning Disabilities opposes the use of discrepancy formulas to determine eligibility for learning disability services and recommends instead comprehensive diagnostic evaluations. (DB)

Meta-analysis was used to arrive at a quantitative synthesis of the results of 94 studies of the validity of Wechsler regroupings for differential diagnosis of learning disabilities. The primary findings indicated that no recategorization, profile, factor cluster, or pattern showed a significant difference between learning disabled and normal…

The article logs descriptive demographic and psychometric data on 1,839 randomly selected learning disabled students from across Iowa. In contrast to the results of other studies, nearly 75 percent of the students in Iowa LD programs met a moderate level of academic discrepancy. Variability was found among the standard scores for the achievement…

To determine the degree of controversy or consensus regarding definitions at the state level, questionnaires focusing on six learning disability topics were sent to each state education agency (SEA) and the District of Columbia. In general, more consensus than controversy exists when broad areas are considered. Changes in some SEA definitions…

Nine procedures assessing the magnitude or statistical significance of ability-achievement discrepancy dealing only with magnitude were evaluated and found to possess one or more serious statistical deficiencies. The approach with the greatest potential involves assessing the statistical significance (reliability) of a discrepancy score and then…

This article suggests some practical resources for classroom teachers in the detection of learning disabilities." (Authors)
