This article addresses the nature of dyslexia and best practices for identification and treatment within the context of multitier systems of support (MTSS). We initially review proposed definitions of dyslexia to identify key commonalities and differences in proposed attributes. We then review empirical evidence for proposed definitional…

The regression-based discrepancy definition of learning disabilities has been suggested by Rutter and Yule as an improvement of the well-known and much criticized achievement-intelligence discrepancy definition, whereby the examinee's predicted reading attainment is substituted for the intelligence score in the discrepancy expression. Even though…

Based on approximately 1,600 referrals of disabled and regular students, 94 empirically derived formulas for assessment of learning disability were used. The most discriminating formula, which included Wechsler Intelligence Scale for Children, Wide Range Achievement Test and grade level variables, resulted in moderate coefficients. (Author/CL)

The author examines implications of the P.L. 94-142 (the Education for All Handicapped Children Act) definition of learning disability, and cites two cases to illustrate two basic problems: that the definition is both overinclusive and underinclusive, and that it does not consider underlying causes. (CL)

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…

Researchers, policymakers, and teacher trainers, identified as being on the "cutting edge" of research and programing in learning disabilities, responded to surveys in 1975 and 1981. The "experts" generally endorsed learning disabilities as viable classifications and asserted that they are identifiable by specific symptoms or syndrome of symptoms.…

Explores current policies and practices concerning the definition, identification, and educational needs of students who are both gifted and learning disabled. Recommendations stress the need for less rigid definitions and cutoff scores for program eligibility and the provision of a wide variety of settings (resource rooms, special classes) and…

The author suggests that controversies over defining learning disabilities (LD) have resulted from confusion between diagnosis and definition and from disagreement over the discrepancy issue. He further suggests that LD students are a subset of age- and ability-referenced underachievers. (CL)

In an attempt to refine the definition of learning disabilities, a new term, dyssymbolia is proposed. (CL)

State guidelines for 1981/82 and 1985/86 were compared to identify trends in definitions and methods used to diagnose learning disabilities (LD). The later guidelines tended to delineate specific achievement discrepancy criteria. However, major components of LD definitions were not altered and IQ cutoffs were not implemented. (Author/DB)

Investigation of the relationship between a statistically determined severe discrepancy between expected and actual achievement levels and subsequent labeling of 733 students as learning disabled found only a slight majority of labeled students manifesting a severe discrepancy suggesting this criterion is inconsistently applied in making…

Three-hundred kindergarten children were screened with a test battery in order to identify children at high-risk of experiencing learning disabilities. (Author/DB)

This article reviews the efforts made since 1962 to define learning disabilities, discusses 11 prominent definitions, identifies important conceptual elements on which the definitions differ, and calls for a consensual acceptance of the National Joint Committee on Learning Disabilities definition. (PB)

The article posits that emotionally disturbed (ED) children routinely are diagnosed as learning disabled (LD), a situation deriving from diagnostic problems and inadequacies of definitions. Among suggestions made for special educators are knowing ED and LD definitions, and becoming assertive as evaluation team members. (MC)

Data from reports of the federally funded Child Service Demonstration Centers (CSDCs) are said to show that only three CSDCs adhered to all criteria in the federal definition of learning disabilities. The author suggests that LD should be adopted as a generic term for all mild handicaps. (CL)
