Decades of research and billions of dollars have been spent to develop and evaluate evidence-based interventions and develop multitiered systems of support (MTSS) toward the goal of more effectively delivering interventions and improving student outcomes. Available evidence, however, suggests interventions are often adopted slowly and delivered…

Interventions are implemented with greater fidelity when their core intent is made explicit. The core intent of this intervention was to increase access to higher order learning opportunities for students with learning disabilities or difficulties in mathematics through use of research and practice from the fields of special education and…

The authors report findings from a systematic observational study of middle school educators (Grades 6-8) in two states who provided reading interventions within Tier 2 and Tier 3 of a Response to Intervention (RTI) framework. Intervention sessions were coded and analyzed to understand (a) the frequency and type of evidence-based strategies…

CAST created "Strategic Reader," a technology-based system blending Universal Design for Learning (UDL) and Curriculum-Based Measurement (CBM) in a digital learning environment to improve reading comprehension instruction. This experimental study evaluates the effectiveness of Strategic Reader using two treatment conditions for measuring…

The purpose of the study was to improve mathematical problem solving for middle school students with learning disabilities by implementing a research-based instructional program in inclusive general education math classes. A total of 40 middle schools in a large urban district were matched on state assessment performance level (low, medium, and…

This article examined the performance of 57 students with learning disabilities (LD) from four middle schools. Students were followed over the course of a school year in their inclusive science classrooms as they alternated between the use of traditional curricular materials for some units of study and materials that were supplemented with video…

This article describes how a purposeful sample of 62 elementary schools from 17 states implemented a Response to Intervention (RtI) framework for reading. School informants answered surveys and were interviewed about differentiated instruction in Tier 1, screening/benchmarking, where Tier 2 interventions were located, typical group size and the…

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…

The National Joint Committee on Learning Disabilities (NJCLD) is a national committee representing 11 organizations concerned about individuals with learning disabilities. The NJCLD considers and discusses contemporary issues in learning disabilities and develops and disseminates reports and statements related to these issues to influence policy…
