At this very moment states and districts use dozens of acronyms, most commonly MTSS (multi-tiered systems of support) and RTI (response to intervention or instruction), to refer to a tiered system of support. You may have also noticed that sometimes in education we take a simple concept and turn into an overly complex system of forms and processes. I have found that when schools start to lose their way or begin to feel overwhelmed with MTSS/RTI, it is important to get back to basics.
