This study examined intervention fidelity (IF) and the extent to which this essential feature of response to intervention (RtI) was included within artifacts (laws and guidance documents) for states requiring RtI for specific learning disability (SLD) identification. Intervention fidelity is defined as the degree to which an intervention is…

We provided a multicomponent academic vocabulary intervention to six English learners with learning difficulties in a fifth-grade general education setting. A multiple probe design across word sets and replicated across students evaluated the effects of the intervention on students' use of expressive language to read and define content-specific…

Many practitioners and state education agency staff would likely agree that the accuracy and consistency of specific learning disability (SLD) eligibility decisions is in need of improvement. One component of the SLD definition particularly controversial in the identification procedures is the evaluation of cognitive processes, primarily due to a…

Unlike other special education categories defined in U.S. law (Individuals with Disabilities Education Act), the definition of specific learning disability (SLD) has not changed since first proposed in 1968. Thus, although the operational definition of SLD has responded to new knowledge and understanding about the construct, the formal definition…

Problems with the current definition of learning disabilities (LD) include its misinterpretation, failure to recognize the developmental nature of LD, and lack of statement about etiology. The definition offered by the National Joint Committee on Learning Disabilities is presented. (CL)

Analysis of 113 studies revealed that researchers most often selected their learning disabled sample on the bases of academic, age and sex, and intelligence components. Less than half used the process or exclusion components or included a description of grade placement. (CL)

After initial efforts to maintain the traditional posture toward learning disabilities in the rewriting of the Rehabilitation Comprehensive Services and Developmental Disabilities Amendments of 1978 (P.L. 95-602), the Rehabilitation Services Administration yielded to a new conceptualization which will now allow the severely LD access to…

The article emphasizes the need for a uniform format for defining the populations selected for research, particularly with learning disabled individuals. The population descriptions from three studies dealing with some aspect of reading are presented and scrutinized in terms of the four categories. (Author/DLS)

This article discusses issues of classification and identification, while evaluating some of the continuing controversies about learning disabilities (LD) related to those topics. The author suggests that many problems have to do with confusion between the two. Despite years of effort and an extraordinary increase in the number of individuals…

A recent overview of the field of learning disabilities (Torgesen, 2004) laid out several issues that will likely consume the field for the foreseeable future, including problems of definition and etiology, differentiation of learning disabilities from other disabilities, and issues in identification and service delivery. It has been approximately…

The history of difficulties with definitions of learning disabilities (LD) is reviewed and the definition proposed by the National Joint Committee for Learning Disabilities is described. LD is seen as a generic term referring to a heterogeneous group of disorders presumed to be due to central nervous system dysfunction. (CL)

The position paper (1981) of the National Joint Committee on Learning Disabilities presents a revised definition of learning disabilities and identifies issues and concerns (such as the limitation to children and the exclusion clause) associated with the definition included in P.L. 94-142, the Education for All Handicapped Children Act. (DB)

The article examines advances and remaining psychometric problems in social skills assessment technology for students with learning disabilities. Assessment is related to a proposed definition of learning disabilities by the Interagency Committee on Learning Disabilities which identifies social skills deficits as a primary learning disability. (DB)

The article looks at the concept of discrepancy between ability and achievement in conceptualizations of learning disabilities. Comparison of ability and achievement scores found generally small average discrepancies, though some wide ranges were evident. Implications of the findings for current and future use of discrepancies as estimators of…

A national survey examined similarities and differences across state agencies, especially departments of special education and vocational rehabilitation, concerning their definitions and eligibility for services to individuals with learning disabilities. Analysis utilized a conceptual framework consisting of 21 components. Significant differences…
