The term multi-tiered system of supports (MTSS), describes an educational framework that provides students with increasingly intensive levels of support to meet their academic and non-academic (behavioral, social and emotional) needs.
The response to intervention (RTI) process is a type of Multi-Tiered System of Support (MTSS) for providing services and interventions to struggling learners at increasing levels of intensity.

See this chart on SLP roles in MTSS and referral [PDF].
Speech-language pathologists (SLPs) can play number of important roles in MTSS and RTI. These roles include:
MTSS has a number of benefits for students and speech-language pathologists. Implementing MTSS can significantly reduce SLPs’ caseloads by addressing students’ educational needs more effectively (Marante & Farquharson, 2021).
Key benefits of MTSS for SLPs include
Studies show that following implementation of MTSS:
MTSS offers a comprehensive approach that not only alleviates the workload of SLPs but also enhances students’ overall educational experience.

Special Collection: Multi-Tiered System of Support
The articles in this collection focus on MTSS implementation, presenting research on the effectiveness of interventions delivered in the classroom and via telepractice. A number of articles focus on the SLP’s role as part of the MTSS team, highlighting the importance of collaboration. Finally, the remaining articles focus on intervention, sharing evidence-based approaches when working with students.
