Multi-Tiered Systems of Support and Positive Behavior Interventions and Supports


MTSS (Multi-Tiered System of Supports) and PBIS (Positive Behavior Interventions and Supports) are a multi-step processes that are put in place to support the academic and behavioral needs of ALL students as early as possible to ensure success.  The goal of MTSS and PBIS are to prevent failure and make all students successful learners.  MTSS and PBIS might also be referred to as the Tier Process and/ or RTI (Response to Intervention).

The MTSS and PBIS processes provide different levels of support depending upon the needs of the child.  At the core of MTSS and PBIS are high quality classroom instruction and behavior interventions.

The Greenwood Leflore Consolidated School District’s MTSS and PBIS model includes a universal screening of all students, multiple tiers of intervention delivery, a collaborative problem-solving approach, and an integrated data collection and assessment system to inform decisions at each tier of instruction and intervention delivery. The MTSS and PBIS model helps aid the GLCSD’s mission to continue to unify, educate, and prepare all students for college and career by providing a high-quality learning experience with support for both the students as well as the teachers. The MTSS and PBIS model emphasis is on school-wide, differentiated universal core instruction at Tier 1; Tiers 2 and 3 provide intensive and increasingly individualized interventions:


Tier 1 (Low Risk) – All students receive effectively, differentiated instruction/behavior provided by a classroom teacher using an evidence-based core curriculum. Tier 1 is expected to bring approximately 80% of students to acceptable levels of proficiency.

Tier 2 (Some Risk) – For students who don’t respond effectively to Tier 1 instruction/behavior, Tier 2 supplements core instruction/strategies using targeted, evidence-based small-group interventions to help them catch up. These supplemental instruction/strategies are expected to bring up to 15% of students to proficient levels.

Tier 3 (High Risk) – Involves the application of intensive, evidence-based interventions that are designed to increase the rate of student progress for approximately 5% of students who need very intensive 1:1 intervention.
