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…

To prevent academic failure and promote long-term success, response-to-intervention (RtI) is designed to systematically increase the intensity of delivering research-based interventions. Interventions within an RtI framework must not only be effective but also be implemented with treatment fidelity and delivered with the appropriate level of…

This study evaluated a scheduling methodology referred to as intervention-based scheduling to address the problem of practice regarding the fidelity of implementing Response to Intervention (RtI) in an existing school schedule design. Employing panel data, this study used fixed-effects regressions and first differences ordinary least squares (OLS)…

Response to Intervention (RTI) is defined by the National Association of State Directors of Special Education (NASDSE) as the practice of providing high-quality instruction and intervention matched to student needs and using learning rate over time and level of performance to make important educational decisions (2007). Both IDEA 2004 and the…

Six middle school students identified as having a specific learning disability or at risk for mathematical difficulties were taught how to solve multi-step equations by using the self-regulated strategy development (SRSD) model of instruction. A multiple-probe-across-pairs design was used to evaluate instructional effects. Instruction was provided…

The Response to Intervention (RTI) framework, a preventive model of universal screening, tiered interventions, and ongoing progress monitoring, poses an interesting consideration for identification and service delivery for children with autism spectrum disorders (ASD). Upon examination of the existing literature, paucity exists regarding how RTI…

Professional confusion, as well as case law confusion, exists concerning the fidelity and integrity of response to intervention (RTI) as a defensible procedure for identifying children as having a specific learning disability (SLD) under the Individuals with Disabilities Education Act (IDEA). Division is generated because of conflicting mandates…

In this review, we explore the extent to which researchers evaluating the efficacy of Tier 2 elementary reading interventions within the framework of Response to Intervention reported on fidelity of implementation and alignment of instruction between tiers. A literature search identified 22 empirical studies from which conclusions were drawn.…

Response to Intervention provides a continuum of instruction across intensity levels through multitiered intervention models. A lot of work to date has been devoted to how to configure tiers to ensure the appropriate increases in intensity. Much less work has been devoted to making adjustments "within" tiers to attempt to forestall the need for…

Since the reauthorization of IDEIA in 2004, school leaders across America have labored toward implementing a new process or model called Response to Intervention, in the hopes of lowering the high rates of students identified as Learning Disabled and increasing overall student achievement, by providing skilled interventions to struggling students.…

Given the vital importance of using a scientific approach for curriculum development, the authors employed a design experiment methodology (Brown, 1992; Shavelson et al., 2003) to develop and evaluate, FUSION, a first grade mathematics intervention intended for students with or at-risk for mathematics disabilities. FUSION, funded through IES…

Written by leading special education researchers with the National Research Center on Learning Disabilities and the University of Kansas, this comprehensive yet accessible reference provides administrators with practical guidelines for launching RTI in their schools. Highlighting the powerful role that RTI can play in prevention, early…

Response-to-intervention (RtI) models utilize a proactive, prevention approach that requires the implementation of a sophisticated, multi-tiered problem-solving process in the regular education environment. Effective and sustainable implementation of these models will necessitate a mechanism to support professional development, treatment fidelity,…

Responsiveness-to-intervention (RTI) is the front-running candidate to replace current practice in diagnosing learning disabilities, but researchers have identified several questions about implementation. Specific questions include: Are there validated intervention models? Are there adequately trained personnel? What leadership is needed? When…
