Multifactorial models of dyslexia have expanded how we consider heterogeneity within the population of children with dyslexia. These models are predicated on the idea that cognitive/linguistic risk factors are not deterministic but instead probabilistic, with the likelihood of difficulties involving an interaction between risk and protective…

Previous studies of K-12 dyslexia legislation have described broad trends in legislative content, such as the presence or absence of screening and intervention requirements. This study uses document analysis to provide a finer-grained description of the laws to highlight critical variation in policy that will directly affect (a) the number and…

Four studies into characteristics and instructional needs of students with learning disabilities are summarized in this article. These studies are also reviewed in the wider context of mathematics intervention research in special education. These studies generally rely on qualitative methodology, and they are best understood in light of a…

The current study examined a solution to high false positive reading risk classification rates in early kindergarten by investigating a method of identifying students with possible false positive risk classifications and returning them to general classroom instruction. Researchers assessed kindergarten students (N = 105) identified as at risk who…

This study investigates how state Departments of Education address the needs of culturally and linguistically diverse (CLD) students as they relate to the identification of students with a specific learning disability (SLD). A qualitative research design of directed content analysis was used to examine each state's regulatory criteria for SLD, as…

The purpose of the current study was to examine academic and cognitive profiles of first graders who responded adequately and inadequately to intensive small-group reading intervention (Tier 2), as well as assess how these profiles differ based on the criteria used for classification of unresponsiveness. Nonresponders were identified using two…

The assessment procedures within Response to Intervention (RTI) models have begun to supplant the use of traditional, discrepancy-based frameworks for identifying students with specific learning disabilities (SLD). Many RTI proponents applaud this shift because of perceived shortcomings in utilizing discrepancy as an indicator of SLD. However,…

An e-mail survey of special education directors was conducted to ascertain practices related to implementation of Response to Intervention (RTI) processes in North Carolina schools. The data indicate that special education directors have information about RTI as a method of identifying students with disabilities, but there is little consensus on…

The policies underlying the specific learning disability (SLD) regulations in the 2004 reauthorization of the Individuals with Disabilities Education Act (IDEA) are analyzed. The analysis focuses on the Response-to-Intervention (RTI) provision ("if the child responds to scientific, research-based intervention") as a diagnostic model,…

This article examines a 1995 treatment validity model as a framework for identifying learning disabilities. This model: (1) examines both student performance and responsiveness to instruction; (2) delays special education referral until the effects of individual student adaptations in the regular classroom have been explored; and (3) verifies that…

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…
