In education, Response to Intervention (commonly abbreviated RTI or RtI) is an approach to academic intervention used to provide early, systematic, and appropriately intensive assistance to children who are at risk for or already underperforming as compared to appropriate grade- or age-level standards. RTI seeks to promote academic success through universal screening, early intervention, frequent progress monitoring, and increasingly intensive research-based instruction or interventions for children who continue to have difficulty. RTI is a multileveled approach for aiding students that is adjusted and modified as needed if they are failing.
In terms of identifying students with specific learning disabilities (SLD), RTI was proposed as an alternative to the ability–achievement discrepancy model, which requires children to exhibit a significant discrepancy between their ability (often measured by IQ testing) and academic achievement (as measured by their grades and standardized testing). Methods to identify students with SLD have been controversial for decades and proponents of RTI claim that the process brings more clarity to the Specific Learning Disability (SLD) category of the Individuals with Disabilities Education Improvement Act (IDEA 2004), while opponents claim that RTI simply identifies low achieving students rather than students with learning disabilities.
Description
RTI is originally a special education term that has broadened into general education framework that involves research-based instruction and interventions, regular monitoring of student progress, and the subsequent use of these data over time to make a variety of educational decisions, including, but not limited to SLD eligibility. To facilitate this broadened conception of RTI, there was a shift to labeling this as one of the approaches of a Multi-Tier System of Supports (MTSS) occurring in schools and the professional literature. The key to the RTI process is the application of scientifically based interventions that have been demonstrated to work in randomized controlled trials. A goal of the RTI process is to apply accountability to educational program by focusing on programs that work rather than programs that simply look, sound, or feel good.
RTI follows a number of core assumptions: The educational system can effectively teach all children Early intervention is critical to preventing problems from getting out of control The implementation of a multi-tiered service delivery model is necessary A problem solving model should be used to make decisions between tiers Research based interventions should be implemented to the extent possible Progress monitoring must be implemented to inform instruction Data should drive decision making
A learning disability is defined as a neurological disorder that affects the brain's ability to receive, process, store, and respond to information. They are a group of disorders that can impact many areas of learning, including reading, writing, spelling, math, listening, and oral expression.
In the process of identifying learning disabilities, RTI differs from the formerly standard "ability–achievement discrepancy" approach in that decisions are based on outcomes of targeted interventions rather than mathematical discrepancies between scores achieved on standardized assessments.
