In this brief, we offer a structure for considering what we know, and what we still need to learn, from research on the
effects of organizing evidence-based practices within an integrated multi-tiered system of support (I-MTSS) framework.

What is the Current State of I-MTSS Implementation in the United States? 

In this brief, we discuss the current state of integrated multi-tiered systems of support (I-MTSS) implementation, as defined by the I-MTSS Research Network (2023), in the United States (U.S.).

Integrated Multi-Tiered System of Support: What’s in a Name?

In this brief, we consider, “What’s in a name?” Specifically, we discuss how (a) educators have described tiered prevention frameworks and (b) their language has evolved in behavioral, academic, and integrated domains.

Brief History of I-MTSS: Major Milestones Toward an Integrated Framework

Many schools, districts, and states now organize support within an integrated multi-tiered system of support (I-MTSS) framework. In this brief, we highlight major milestones in publication, legislation, and funding that have propelled educators toward an I-MTSS framework

What is an Integrated Multi-Tiered System of Support?

This brief defines an Integrated Multi-Tiered System of Support (I-MTSS) as a comprehensive and equitable prevention framework for improving the outcomes of all students, including students with or at-risk for disabilities, through integrated academic and behavioral support. Key components of an I-MTSS framework are identified and explained.

IES MTSS-B Trial: Key Takeaways for District and State Leaders

The purpose of this brief is to review the latest randomized controlled trial (RCT) examining effects of positive behavioral interventions and supports (PBIS), an example of a multi-tiered system of support for behavior (MTSS-B), on a range of student outcomes. We share findings and key takeaways from this new study, in the context of the broader research literature, to guide local educational agency (LEAs) and state educational agencies (SEAs) in their use of MTSS to improve student outcomes.
