Multi-tiered Systems of Support (MTSS), formerly Response to Intervention (RtI),  is a framework of instruction that provides support to ALL students to ensure mastery of grade-level content standards. The tiers of MTSS provide varying levels of support for students who are struggling to reach mastery as well as those to exceed grade-level.

MTSS provides a framework that incorporates high-quality core instruction, screening, progress monitoring and data-based decision making to provide effective instruction.

MTSS centers on three tiers of instruction:

Tier 1 instruction, also known as core instruction, is at grade level instruction that each student receives on a daily basis. For the majority of students, Tier 1 instruction will meet their academic needs.  

Tier 2 instruction is supplemental instruction, at grade level, for students who need additional support in learning grade level material. Tier 2 instruction is intended to be timely and coordinated with Tier 1 instruction.  

Tier 3 instruction is intensive support provided to students who are struggling with significant learning gaps and need academic and/or behavioral support. Typically these students do not have the appropriate grade level skills yet to be successful in solely Tier 1 and Tier 2 instruction. Tier 3 provides yet an additional level of intervention to help students develop foundational skills.Students receiving Tier 3 instruction also receive Tier 1 and 2 instruction. Students are entered into the Tier 3 interventions based on a referral to the School Intervention Team (SIT).

At all three levels, student progress is monitored regularly.All students are assessed with benchmark assessments three times per year.Students receiving Tier 2 and 3 instruction are progress monitored more frequently.
