Multi-Tiered Systems of Support (MTSS)

Multi-Tiered Systems of Support (MTSS)

The MBUSD Board Goal 1 is to maximize the academic success of all students. We are proud and excited to share with you the important work that we are doing to provide your child with the support they need to be successful.  We will call this focused proactive approach to systematizing, organizing, and providing support: “MTSS”. Multi-Tiered System of Supports (MTSS). OR MTSS provides a framework for addressing the needs of the whole child. 

What is MTSS?

MBUSD’s Multi-Tiered System of Supports also known as MTSS defines a system that includes support in the areas of social-emotional, behavior, and academics to ensure every learner can be successful.

Universal Design for Learning (UDL)

Universal Design for Learning (UDL) is a framework to improve and optimize teaching and learning for all people based on scientific insights into how humans learn (CAST, 2022). The framework translates an understanding of neural networks and brain-based learning into practice using three guiding principles:

  • Multiple means of engagement (the “why” of learning)
  • Multiple means of representation (the “what” of learning)
  • Multiple means of action and expression (the “how” of learning)

UDL is the design and delivery of curriculum and instruction to meet the needs of all learners by providing them choices for what they are learning, why they are learning, and how  they will share what they have learned (Novak, 2016)

Universal Screener

A central component of all MTSS models is an early screening of all students to identify those at risk for academic, social-emotional,  and/or behavior difficulties.
