As a former special education teacher/case manager and now a special education university supervisor, I have spent many an hour discussing MTSS (Multi-Tier System of Supports). My university students and I have reviewed the countless interventions and supports they are exposed to during their required observations, practicums, and culminating student teaching experiences. After conducting an informal poll with my most recent cohort, I found that many students felt that MTSS has a confusing reputation in the field. Further, I noticed that some students were using the term MTSS interchangeably with terms such as RTI, PBIS, and even pre-referral screening. As a result, I decided to take a moment to clear up what MTSS is, and what it is not.
Multi Tiered System of Supports (MTSS) is a collaborative, evidence-based, approach to differentiating and personalizing instruction and intervention, across academics and behavior for all students—so that every student can achieve academic and life success.
