This partner session from the 2021 Virtual CEEDAR Cross State Convening features an interactive exploration of 3 OSEP-funded national centers: The PROGRESS Center, the National Center on Intensive Intervention (NCII), and the Lead for Literacy Center (L4L). Presenters explore a wide variety of resources that are openly available to SEAs, EPPs, and LEAs and that support implementation of evidence-based practices (EBPs) within a multi-tiered system of supports (MTSS). Resources include online course content for EPPs, tools for designing and implementing high-quality IEPs, and other tools/resources geared for administrators to support literacy teaching and learning.
