(Only the lead administrator or designee needs to register) The multi-tiered system of supports (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 supports (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, components of implementation, and the importance of ongoing professional development and support. District-level MTSS teams should consist of directors and coordinators who lead and support in the areas of academics, behavior, and mental health.
