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…

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)

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.…

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)

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)

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)

This article addresses the proposal of Shaw and others (1995) to replace the current federal definition of learning disabilities with an operationalized version proposed by the National Joint Committee on Learning Disabilities in the reauthorization of the Individuals with Disabilities Education Act. Comparison of Shaw's recommendations with…

Discusses how the Guckenberger v Boston University case illustrates the interaction of the psychometrics of ability differences with the concept of learning disability and with the sociopolitics of schooling and society. Urges a more inclusive definition of learning disability which abandons aptitude-achievement discrepancy requirements and a more…

The lack of a firm definition of emotional disturbance, accompanied by a dearth of valid identification methods and absence of effective programing are cited as major problems. The authors emphasize the importance of basic skills instruction, behavior management leading to self-control, and reeducation of the student's total environment. (CL)

The author traces efforts to define and redefine learning disabilities (LD). The inclusion of children in LD classes who do not meet requirements of the definition is seen as a common yet dangerous practice. (CL)

Intake placement data were collected from the files of 1,966 students labeled and served as learning disabled in Child Service Demonstration Centers (CSDC) in 22 states. There appeared to be a lack of consistency in the characteristics of students labeled learning disabled. (Author)

Reviews definitional issues of learning disabilities in the context of the Guckenberger v. Boston University federal lawsuit. Four major questions are addressed: (1) Who is learning disabled?; (2) How should learning disabilities be assessed?; (3) Who is qualified to decide whether or not an individual has a learning disability?; and (4) What…

This study evaluated 150 elementary students previously referred to school study teams for possible learning disability (LD) as defined by a discrepancy between IQ and performance on a standardized achievement test. Comparison with actual school-based decisions found fewer than half of students certified as LD by local schools evidenced the…
