Multi-Tiered Framework

A Multi-Tiered System of Support (MTSS) is a data-driven, problem-solving framework to improve outcomes for all students. MTSS relies on a continuum of evidence-based practices matched to student needs. PBIS is an example of MTSS centered on social behavior.

Three Tiers of Support

MTSS emerged as a framework from the work conducted in public health emphasizing three tiers of prevention. Schools apply this model as a way to align to academic, behavioral, social, and emotional supports to improve education for all students. It is important to remember these tiers refer to levels of support students receive, not to students themselves. Students receive Tier 2 supports, they are not Tier 2 students.

Key Components at Every Tier

Each tier has its own set of systems and practices, but some key components appear across every level. Each of these features needs to be present in order for MTSS to be implemented with fidelity.

• Practices are based on evidence to be effective in a similar context with similar populations. 
• Practices are organized along a tiered continuum beginning with strong universal supports followed by intensified interventions matched to student needs. 
• Data is collected and used to screen, monitor, and assess student progress.
• Resources are allocated to ensure systems and practices are implemented with fidelity over time.
