The RTI has two main purposes. The RTI process is used to ensure that specific
students receive support and remedial instruction once they are identified as having learning disabilities or difficulties. It also ensures that appropriate professionals gather data, document, and assess the effectiveness of the remedial instruction and provide them with the decision about whether that students needs special education services or not. The RTI uses a Three-Tiered approach. Tier 1 is used for the higher instruction and focuses more towards reading but can be applied towards math or behavior. Students will have continuous monitoring of progress till the students shows they can move on to the second tier. Tier 2 usually entails small-group instruction once to several times a week for a more intensive instruction. The smaller group of students who still tend to struggle in the small group instruction are recommended for additional instruction. Tier 3 is considered the more intensive level, usually having a daily one-on-one instruction outside the classroom. At times, tier 3 may include the permanent decision that a student needs special education and is used as the official decision maker.
“Variations in the tiers used to deliver RTI services, schools use different approaches in implementation, such as problem-solving, functional assessment, standard protocol, and hybrid approaches. Although there are many formats for how a school might implement RTI to best serve the needs of its students, in every case RTI can be a school-wide framework for efficiently allocating resources to improve student outcomes (Friend, 2018)
