Multi-Tiered System of Supports (MTSS) and Response To Intervention (RTI) are the educational framework for Iron County School District. The framework ensures systemic, evidence-based practice to ensure that all students learn at high levels through instruction and tiered levels of support.

Universal, or Tier 1 instruction, is the curriculum that is provided to all students. Tier 1 instruction should be implemented effectively before considering Tier 2 or Tier 3 services.

Targeted, or Tier 2 instruction and supports, are provided to remediate or accelerate student learning in small groups. Tier 2 instruction and supports are targeted to the specific needs of each student.

Intensive, or Tier 3 supports, are additional supports that dig even deeper into what each individual student needs to succeed. These supports are a response to students with significant challenges to overcome in order to experience success.

Tier 2 and Tier 3 instruction and supports are provided in addition to Tier 1 instruction. The model is illustrated below.
