Response to Intervention (RtI)
RtI and students with significant disabilities. The concept of RtI, or Response to Intervention, first appeared on the national special education radar as a part of the IDEA 2004 legislation. For most special educators, the emphasis has been placed on students with a specific learning disability. The IDEA 2004 legislation stated: “In determining whether a child has a specific learning disability, a local education agency may use a process that determines if the child responds to scientific, research-based intervention as a part of the evaluation procedures…” This legislation provided an alternative to the use a discrepancy between achievement measures and intellectual disability measures to determine the presence of a specific learning disability. The bigger the discrepancy, the higher the probability that the student would be designated “learning disabled.” The RtI option is often linked to another part of the IDEA 2004 legislation allowing educators to use up to 15% of federal special education funding for students not identified as needing special education services, but needing support in the general education environment. One of the outcomes of this legislation was an emphasis on struggling readers in the k-3 grades. Many have assumed that the RtI concept has little instructional relevance for students with significant disabilities. An overview of RtI and the associated legislation is provided in a summary document on RtI.
What is RtI. The core principles of RtI, as discussed in the above-listed summary document, are:
1. We can effectively teach all children.
2. Intervene early.
3. Use a multi-tier model of service delivery.
4. Use a problem-solving method to make decisions within a multi-tier model.
5. Use research-based, scientifically validated interventions/instruction to the extent
available.
6. Monitor student progress to inform instruction.
7. Use data to make decisions.
8. Use assessments for three different purposes: (a.) screening applied to all
children to identify those who are not making progress at expected rates; (b.)
diagnostics to determine what children can and cannot do in important academic
and behavioral domains; and (c.) progress monitoring to determine if academic or
behavioral interventions are producing desired effects.
Most of these core principles of RtI are just as relevant to the design and implementation of instruction for students with significant disabilities as they are to other students with disabilities.
Key Components of RtI. When we examine the three key components of RtI, the relevance of RtI for students with significant disabilities becomes even more pronounced. These three key components, as noted in the above-listed summary document, are:
1. High-quality instruction/intervention, which is defined as instruction or
intervention matched to student need that has been demonstrated through
scientific research and practice to produce high learning rates for most students.
Individual response is assessed in RtI and modifications to instruction/
intervention or goals are made depending on results with individual students.
2. Learning rate and level of performance are the primary sources of information
used in ongoing decision making. Learning rate refers to a student’s growth in
achievement or behavior competencies over time compared to prior levels of
performance and peer growth rates. Level of performance refers to a student’s
relative standing on some dimension of achievement/performance compared to
expected performance (either criterion- or norm-referenced). Decisions about the
use of more or less intense interventions are made using information on learning
rate and level. More intense interventions may occur in general education
classrooms or pull-out programs supported by general, compensatory or special
education funding.
3. Important educational decisions about intensity and likely duration of
interventions are based on individual student response to instruction across
multiple tiers of intervention. Decisions about the necessity of more intense
interventions, including eligibility for special education, exit from special
education or other services, are informed by data on learning rate and level.
What Works. These three key components have one central theme. The individual student’ s response to instruction is the key factor driving changes in the quality and quantity of instruction. To the extent that students with significant disabilities have major gaps between with their peers on academic and behavioral measures, the concept of RtI may be most relevant for these clients, their families, and the educational teams serving these clients.
