A PHASED IMPLEMENTATION FRAMEWORK FOR SYSTEMWIDE SCALE-UP OF MULTI-TIERED SYSTEMS OF SUPPORT FOR BEHAVIOR (MTSS-B)

Abstract

The implementation of Multi-Tiered System of Supports for Behavior (MTSS-B), also referred to as Schoolwide Positive Behavior and Supports (SWPBIS), is a growing priority for schools seeking to promote positive student outcomes through evidence-based practices. However, sustainable and scalable implementation remains a challenge, particularly in the areas of Tier 2 and Tier 3 interventions, leadership team capacity, and staff turnover. This article provides a phased implementation framework designed to guide educational agency practitioners, MTSS-B Facilitators, and school-level MTSS-B Leadership Teams through phased implementation with benchmarks that emphasize fidelity, professional learning, universal screening, intervention development, and sustainability planning. Through a comprehensive research review of implementation science, Positive Behavioral Interventions and Supports (PBIS) research, and recent findings on timing and fidelity of MTSS installation, this framework integrates evidence-based tools and methods for systemic scale-up. Key findings highlight the importance of intentional pacing in the installation of MTSS-B, data-informed intervention matching and progress-monitoring, and staff induction systems to mitigate the effects of staff turnover. Practical guidance is provided in an MTSS-B Phased Implementation Plan for systems’ MTSS-B Facilitators to guide school-level MTSS-B Leadership Teams when building systems that are operational, adaptive, and sustainable. This article contributes to the MTSS-B literature by synthesizing research into a practical, practitioner-focused, benchmark-driven model to support schools in achieving long-term fidelity, equity, and sustainability.
