We use critical qualitative methods to demonstrate how ambiguities present in definitions of learning disability (LD) and processes for determining LD eligibility under IDEA result in inequitable outcomes for minoritized students. To investigate this issue, we first outline how the LD label is situated within medical and psychological…

Recently, the United Nations Educational, Scientific, and Cultural Organization (UNESCO) reported that although countries around the world must ensure that students with disabilities receive free, inclusive, and appropriate education, students with disabilities are less likely to complete primary or secondary school in many countries. Though this…

We review the evolution of the conceptualisation of dyslexia and along with it the current, 21st century definition of dyslexia. Our starting point is the seminal report by Pringle Morgan in 1896, followed by early 20th century reports by Hinshelwood, and continuing with concepts of brain injury and minimal brain dysfunctions then to the emergence…

The definitions and educational policies related to learning disabilities have been updated throughout the last two decades since the passing of the Special Education Promotion Act (1994) in the Republic of Korea (South Korea). In particular, the definition of learning disabilities was entirely revised in the Special Education Act for Individuals…

Specific learning disability (SLD) identification and eligibility practices are evolving and sometimes contentious. This article describes the historical context and current status of the SLD definition, legislation, regulation, and case law related to the identification of students eligible for special education services. The first part traces…

The Individuals with Disabilities Education Act (IDEA; P.L. 108-446) is the primary source of federal funding to states for the identification and education of children with disabilities. The majority of IDEA appropriations are allocated to states by formula to carry out activities under Part B, which covers 14 disability categories. Each state is…

This brief report summarizes research on dyslexia. It is intended to provide an initial look at this common type of learning disability that impacts 1 in 5 students. Included in the brief are links to the original source material and to supplementary resources and videos to learn more.

The purpose of the White Paper is to provide additional information for and guidance to the federal government, professional organizations, practitioners, and the public. The Learning Disabilities Association of America (LDA) is hopeful that this document will facilitate legal, regulatory, policy, and training decisions, and ultimately, service…

While special education law has been amended several times since the statutory definition of a Specific Learning Disability (SLD) was created in 1968, there continues to be ambiguity within the field regarding the definition as well as the diagnostic criteria. This inevitably leads to a lack of consistency in diagnosis within states and among…

In this article, a new definition of twice-exceptional children is proposed. In addition to introducing this new definition, the authors provide a research-based rationale for the definition, offer a clear profile of twice-exceptional youth, and summarize the development of new programs and practices to enable these students to develop their gifts…

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…

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.

The extent to which identification as learning disabled is a function of the definition used and the extent to which different classifications would result from use of different definitions were examined in a study involving 51 students (6 to 12 years old) referred for psychological evaluation as a result of academic difficulties. The school…

The paper surveys and analyzes the definitions of learning disabilities proposed by experts in the field and by legislative mandate. The discussion is organized around five topics: (1) historical developments, (2) common elements in the definitions, (3) criticisms of federal definitions, (4) theoretical versus operational definitions, and (5)…

Two responses to the Federal definition of learning disability in the proposed regulations for Public Law 94-142 are presented. (CL)
