Response to Intervention
RTI
June 18, 2010
The Individuals with Disabilities Education Act (IDEA) 2004 authorized local education agencies to use Response to Intervention (RTI) models. RTI is an integrated approach that includes general, remedial, and special education. It is based on a three-tiered model that monitors student progress with different levels of intervention intensity. By providing scientifically-based interventions to students, monitoring progress on interventions, and using this information to determine who is in need of more intensive services, RTI also builds on the requirements of No Child Left Behind (NCLB).
California has expanded on the philosophy of Response to Intervention. California has adopted, Response to Instruction and Intervention. RtI² is meant to communicate the full spectrum of instruction, from general core, to supplemental or intensive, to meet the academic and behavioral needs of all students. RtI² integrates resources from general education, categorical programs, and special education through a comprehensive system of core instruction and interventions to benefit every student.
