In a multi-tiered system of supports, what percentage of students is typically expected to meet grade-level expectations in Tier 1?

In a multi-tiered system of supports (MTSS), Tier 1 represents the foundational level of instruction that is provided to all students in the general education classroom. The expectation is that a significant majority of students, typically around 80%, will be able to meet grade-level expectations at this tier. This percentage reflects the effectiveness of high-quality, differentiated instruction and universal interventions that are designed to support diverse learners.

Meeting this benchmark indicates that Tier 1 instruction is adequately addressing the needs of most students, allowing them to engage with the curriculum effectively without additional supports. When fewer than 80% of students are successful, it suggests that the instructional strategies or curriculum may need to be re-evaluated or adjusted to better serve the entire class.
