What is it?
Tier 1 includes the core instruction that is accessible to all students. It is comprised of standards-driven, research and evidence-based curriculum, resources, assessments, and practices. Effective instruction within Tier 1 is developed using the principles of Universal Design for Learning (UDL) and implements differentiation to meet the specific needs of all students. Strong Tier 1 instruction ensures the majority of students (80% or more) can reach established academic benchmarks without additional intervention. A comprehensive professional development program, established professional learning communities (PLCs), and invested administrative and instructional leadership are critical to implementing quality core instruction at Tier 1.
Universal screening for students is integral to a MTSS and is an essential component of Tier 1. Universal screening through benchmark, criterion-references, and/or classroom-based measures provide critical data for making decisions about instruction at this tier and developing targeted and individualized interventions for Tier 2 and Tier 3.
