What is MTSS?

A Multi-Tiered System of Supports (MTSS) is a prevention framework that integrates all students. It is a term used to describe an evidence-based model of schooling that uses data-based problem solving to integrate standards-based instruction, interventions, and assessments to address the full range of student academic and behavioral needs present in today’s classroom. MTSS, Response to Instruction and Intervention (RtI), and Positive Behavioral Interventions and Supports (PBIS) are often spoken of synonymously, and for those new to MTSS, it can be difficult to determine what people mean when these terms are used interchangeably. It is important to keep in mind, though, that MTSS is a framework for aligning resources and initiatives; it is a method of organization. As such, MTSS encompasses both RtI and PBIS, and systematically addresses support for all students. MTSS encompasses all of the academic, behavioral, and social-emotional demands of learning.

MTSS is a key part of the broader Charlotte County Public Schools (CCPS) strategic framework to support all learners and ensure equitable access to robust, high-quality education. MTSS provides the structure for the District to prioritize the academic, behavioral, and mental health needs of all students, including our Students with Disabilities (SWDs), students with advanced learning needs, and English Language Learners (ELL).

In CCPS, MTSS promotes a well-integrated system, where the needs of all learners are identified and supported early through increasing levels of instructional intensity and time. MTSS provides high-quality, standards-based instruction and intervention that is matched to students’ academic, behavioral and social/emotional needs to maximize the impact on student outcomes. Multi-Tiered instruction refers to all of the strategies, interventions, and other resources that are used to help all students achieve. An effective system blends culturally responsive academic and behavior supports to create effective environments that address a range of student needs.

Integration of MTSS into School and District Plans for Supporting Student Success

The State of Florida requires schools and districts to submit plans for improving student achievement. ​

  • MTSS and the Comprehensive Evidence-Based Reading Plan (CERP): The CCPS Reading Plan identifies Core, Supplemental and Intensive interventions for reading K-12​

  • MTSS and the Special Policies & Procedures Manual (SP&P): States need for response to interventions (RtI) in identifying students with disabilities​

  • MTSS and the District Strategic Plan: The District Strategic Plan includes specific implementation and monitoring of an Early Warning System to identify students with two or more early warning signs and to connect those students with appropriate interventions.

  • MTSS and the Schoolwide Improvement Plans (SIP): School Improvement Plans identify ways to improve student achievement across tiers. MTSS action plans are used to inform SIP planning.



MTSS is a universal education system in which all educators use an effective and efficient multi-tiered system of supports to ensure student growth in academic, behavioral, emotional, and life skills.

It 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.
