1% Toolkit: Multi-Tiered Systems of Support (MTSS) for Students with the Most Significant Cognitive Disabilities (NCEO Tool #15)


The purpose of this tool is to provide information on the Multi-Tiered Systems of Support (MTSS) for students with the most significant cognitive disabilities for parents in the form of (a) a fact sheet, and (b) a set of frequently asked questions (FAQs) that provide additional details about MTSS. These parent resources are available for states to adapt to share with districts, parent organizations, and parents. This resource was developed through a collaborative process with members of the TASH Inclusive Education Community of Practice (CoP) and staff from forty-nine states and the Bureau of Indian Education (BIE) who participated in the 1% CoP.
