Response to Intervention (RTI).
Although not new or limited to special education, RTI initially appeared as policy in the Individuals with Disabilities Education Improvement Act of 2004 (IDEA 2004), and it has conceptual and empirical foundations in, for example, applied behavior analysis, curriculum-based measurement, precision teaching, pre-referral intervention, teacher assistance teaming, diagnostic prescriptive teaching, data-based decision making, early universal screening and intervention, behavioral and instructional consultation, and team-based problem solving (Sugai, 2007).
