(Only the primary point of contact/team lead needs to register) The Multi-Tiered System of Support (MTSS) framework can be considered the umbrella for other support systems, such as data-based individualization (DBI), response to intervention (RtI), and positive behavior intervention and support (PBIS). Through MTSS, schools identify students in need of additional support and provide them with evidence-based interventions to reduce academic and behavioral gaps. MTSS Essentials One provides an overview of MTSS and guides participants through establishing a problem-solving team, implementation plan, and planning for ongoing professional development and support. District-level MTSS teams may consist of directors and coordinators that lead and support in the areas of academics, behavior, and mental health.
