with Learning Disabilities

IDEA 2004 allows the use of a student s response to scientific, research-based intervention (20
U.S.C 1414 (B)(6)(A)) as part of an evaluation. Response to intervention (RTI) functions as an
alternative for learning disability (LD) evaluations within the general evaluation requirements of
IDEA 2004. The statute continues to include requirements that apply to all disability categories,
such as the use of validated, non biased methods, and evaluation in all suspected areas of
difficulty. IDEA 2004 adds a new concept in eligibility that prohibits children from being found
eligible for special education if they have not received instruction in reading that includes the
five essential components of reading instruction identified by the Reading First Program. These
requirements are those recognized by the National Reading Panel: phonemic awareness, phonics,
reading fluency (including oral reading skills), vocabulary development, and reading
comprehension strategies. RTI is included under this general umbrella. By using RTI, it is
possible to identify students early, reduce referral bias, and test various theories for why a child
is failing. It was included in the law specifically to offer an alternative to discrepancy models.
A key element of an RTI approach is the provision of early intervention when students first
experience academic difficulties, with the goal of improving the achievement of all students,
including those who may have LD. In addition to the preventive and remedial services this
approach may provide to at-risk students, it shows promise for contributing data useful for
identifying LD. Thus, a student exhibiting (1) significantly low achievement and (2) insufficient
RTI may be regarded as being at risk for LD and, in turn, as possibly in need of special education
and related services. The assumption behind this paradigm, which has been referred to as a dual
discrepancy (L. S. Fuchs, Fuchs, & Speece, 2002), is that when provided with quality instruction
and remedial services, a student without disabilities will make satisfactory progress.
The concept of RTI has always been the focus of the teaching/learning process and a basic
component of accountability in general education: In other words, does instruction (i.e.,
strategies, methods, interventions, or curriculum) lead to increased learning and appropriate
progress? In the past few years, RTI has taken on a more specific connotation, especially in the
Individuals with Disabilities Education Improvement Act of 2004 (IDEA 2004),2 as an approach
to remedial intervention that also generates data to inform instruction and identify students who
may require special education and related services. Today, many educators, researchers, and
other professionals are exploring the usefulness of an RTI approach as an alternative that can
provide (1) data for more effective and earlier identification of students with LD and (2) a
systematic way to ensure that students experiencing educational difficulties receive more timely
and effective support (Gresham, 2002; Learning Disabilities Roundtable, 2002, 2005; National
Research Council, 2002; President s Commission on Excellence in Special Education, 2002).
Importance of RTI
According to current early reading research, all except a very few children can become
competent readers by the end of the third grade. RTI is a process that provides immediate
intervention to struggling students at the first indication of failure to learn. Through systematic
screening of all students in the early grades, classroom teachers identify those who are not
mastering critical reading skills and provide differentiated intervention to small groups of
students. Continuous progress monitoring of students responses to those interventions allows
teachers to identify students in need of additional intervention and to adjust instruction
accordingly.
