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…

The present study seeks to evaluate a hybrid model of identification that incorporates response to instruction and intervention (RTI) as one of the key symptoms of reading disability. The 1-year stability of alternative operational definitions of reading disability was examined in a large-scale sample of students who were followed longitudinally…

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…

The use of the processing component for learning disabilities (LD) definitions is discussed by examining its theoretical basis, large-scale implementation, and researched classroom effectiveness. Results indicate the processing definition of LD does not differentiate students with LD from low achievers, is inconsistently implemented, and does not…

This article reviews problems in identification of learning disabilities and considers proposed alternatives to present procedures. It argues that the major problems of over identification, variability, and specificity, can be eliminated by increasing specificity and consistency of state criteria and strict adherence to identification criteria on…

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)

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 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…

Responsiveness to intervention (RTI) is being proposed as an alternative model for making decisions about the presence or absence of specific learning disability. We argue that many questions about RTI remain unanswered, and that radical changes in the proposed regulations are not warranted at this time. Since many fundamental issues related to…

Problems with restricting learning disabilities to a range of mild handicaps are noted and five areas of controversy affecting severely learning disabled students are addressed: definitions, student characteristics, identification criteria, educational methods and technology, and educational services. (CL)

This article examines the problem of definition in learning disabilities. It discusses the failure of conceptual definitions to provide a clear idea of what learning disabilities are, examines the true nature of available definitions as stipulative definitions, and notes the difficulty in conceptualizing and implementing operational definitions.…

The National Joint Committee for Learning Disabilities' definition of learning disabilities is presented, followed by a discussion of parameters to be considered in operationalizing the definition. Major definitional issues are then explored, including using testable and meaningful constructs, linking definitions to neuropsychological evidence,…

This study addressed the validity of using a five-state multifaceted approach to defining reading disabilities. Comparison of 204 reading-disabled (selected by criteria such as intraindividual differences and low achievement) and normally achieving junior high students on motivational, cognitive, and metacognitive variables (usually associated…

Two position papers by the National Joint Committee on Learning Disabilities (NJCLD) present (1) the core competencies needed by regular and special education teachers who work with children with learning disabilities, and (2) recommendations for operationalizing the five constructs underlying the NJCLD definition of learning disabilities for…
