6 Critical Domains of MTSS

MTSS is comprised of Six Critical Domains as pictured in the honeycomb design above.  Much of this manual focuses on the areas of Multiple Tiers of Instruction and Intervention, as well as the Problem Solving Process and Data and Evaluation.  However, all six elements are equally important to a well-functioning MTSS as the inter-relationship among the six critical domains is optimized when school and district leaders share responsibility for MTSS implementation to improve student outcomes and reach school and district improvement goals. 

Multiple Tiers of Instruction and Intervention: Tiered instruction and intervention is the foundation of an MTSS system.

Problem Solving Process: Data-based problem solving is the process used to make educational decisions within an MTSS. 

Data/Evaluation: Given the importance of data-based problem solving for making decisions about multi-tiered instruction and intervention, the need for an accurate, fluid data and evaluation system is clear. 

Leadership: Effective leadership at both the school and district level is critical to the success of an MTSS. Effective leaders consistently communicate their vision and expectations for the implementation of MTSS. 

Building the Capacity/Infrastructure: School and district-wide capacity and infrastructure are required in order to implement and sustain an effective MTSS. 

Communication and Collaboration: Ongoing communication and collaboration are essential for key stakeholders to understand and enact the practices that comprise an MTSS.
