Response to Intervention (RTI), was introduced in 2004 during the revision of the federal law known as the Individuals with Disabilities Act (IDEA). It was introduced as a method to provide intensive assistance to children who are at risk of a disability and the overidentification of children with specific learning disabilities. The reason for RTI is to prevent children from failing in both academics and behaviors by providing them with research-based instruction, universal screening, and early intervention. RTI has a three-tier model of intervention; the first tier focuses on core curriculum, the second tier focuses on intervention for students in small groups, and lastly, those who continue to have difficulty receive intervention services
