 * Scientifically-Based Core Instruction and Intervention**

Instruction and intervention at all levels of intensity (Tiers 1, 2, and 3) within an RtI model is scientifically-based, or based on rigorous research in content covered and methods used. For example, in the area of reading, the content of scientifically-based instruction and intervention programs includes the "Big Ideas" found in research and outlined by the National Reading Panel: phonemic awareness, alphabetic principle, fluency, comprehension, and vocabulary. Scientifically-based instructional methods for all content areas include modeling, providing multiple opportunities for active student responding and guided practice, and providing corrective feedback. Appropriate scientifically-based instructional materials at all levels of intensity provide a systematic scope and sequence that includes clear guidelines about which skills are taught and the order in which content are introduced. These materials can be used to differentiate instruction based on the level of student need (i.e., to support students, including English language learners, who are performing above grade level, at grade level, slightly below grade level, significantly below grade level, etc.). The scientifically-based instruction and intervention materials employed are appropriate for a system that uses student data and clearly-specified decision rules to guide implementation.

**Fidelity of Instruction**
Scientifically-based instruction and intervention at all levels of intensity (Tiers 1, 2, and 3) within an RtI model is delivered with fidelity (as intended by the program developers). To support high quality instruction and prevent drift in the intervention plan, an adherence plan is developed for core instruction, supplemental programs, and interventions. The RtI leadership team, including teachers, participates in the development of this plan, and the plan is not used for teacher evaluation. As part of the adherence plan, an impartial professional who is familiar with the instruction and intervention programs regularly observes instruction and intervention delivery using fidelity checklists and adherence protocols and provides feedback to the interventionists. Adherence checks are made more frequently as the intensity of interventions increases.
