Which tier within the Multi-Tiered System of Supports (MTSS) is characterized by universal support?

• A. Tier 1
• B. Tier 2
• C. Tier 3
• D. Tier 4

Answer: (A)

The tier characterized by universal support within the Multi-Tiered System of Supports (MTSS) is Tier 1. This tier represents the foundational level of support provided to all students in a general education environment. At this stage, high-quality instruction and behavioral support are designed to meet the needs of the majority of students. The goal is to create an inclusive learning environment where all students have access to a rigorous curriculum and effective teaching strategies.

In Tier 1, interventions and support strategies are implemented proactively, with the assumption that the majority of students will respond positively to these universal supports. This tier includes differentiated instruction, ongoing assessment, and continuous monitoring of student progress to ensure that all students can achieve their academic and behavioral goals. If students do not respond adequately in Tier 1, they may then move to Tier 2, where more targeted interventions are provided, and subsequently to Tier 3 for even more individualized support, should that be necessary.
