• RTI is built on the idea of intervening early to prevent failure and to maximize the effectiveness of grade level curriculum and instruction. It is not an initiative or program, but rather a framework for providing high quality curriculum and instruction to all students and intervention support for some students. The National Center on Response to Intervention (NCRTI) believes that comprehensive RTI Implementation will contribute to more meaningful identification of learning and behavioral problems, improve instructional quality, provide all students with the best opportunities to succeed in school, and assist with the identification of learning disabilities and other disabilities.
