Tier 1 in RTI refers to universal interventions that are available to all students.

• A. False
• B. Only for students with IEPs
• C. Tier 1 refers to universal interventions for all students
• D. Only in high school

Answer: (C)

In RTI, Tier 1 represents universal interventions for all students. This means the core instruction and supports are provided to every student in the general education setting, using high-quality, evidence-based teaching practices and curricula. Universal screening is used to check how well all students are responding to this core instruction, so that those who aren’t meeting targets can be identified early and offered additional support.

This tier isn’t limited to students with IEPs, and it applies across all grade levels, not just high school. When a student struggles despite effective Tier 1 instruction, they receive more targeted help in Tier 2 (small-group interventions) or more intensive, individualized supports in Tier 3, but Tier 1 remains the foundation for every learner.
