Response To Intervention or RTI can be defined as a process of academic intervention that has been introduced in the United States for providing early and effective assistance to kids who face difficulty in the normal learning procedure. Response to intervention also functions as a data dependent method for diagnosing the various learning disabilities. This process can be employed at both individual and group levels.
Description of RTI
Researchers have developed an ability-achievement discrepancy model which helps in the formative evaluation and identification of the learning disabilities in children. Along with this model, certain standardized tests are done which help in revealing the severe discrepancy between the academic achievement and IQ level of a child. This method, along with the Disabilities Education Improvement Act (IDEA, 2004), also throws light on that category of children who display Specific Learning Disability (SLD). The SLD is formed by the residual category for kids who display moderate problems in learning.
Role of RTI
The main role of the RTI is to prevent any kind of academic failure and this, it tries to accomplish by early quality- intervention and conducting progress measurement frequently. They employ intensive researched instructional interventions for that group of children who still continue to show learning disability.
Classification of RTI
In academic literature, RTI uses a Problem Solving Model or a Standard Protocol Approach, both of which solve to identify the learning disability in a student. The main difference between the two is that the latter uses a more systematic approaching employing a universal screening procedure. The Curriculum Based Measurement (CBM) and other such methods are for flagging the children who fail to meet the expected performance levels. The Problem Solving Model on the other hand, refers the child to a multidisciplinary team or a student success team. After all these interventions have been applied and proven effective, the student may be referred for IDEA which is additional services for special education.
