The IRIS Center is a national center dedicated to improving education outcomes for all children, especially those with disabilities, by developing free, online resources about effective evidence-based practices and interventions.

IRIS Modules, our center's signature resource, are developed using adult learning theory and translate the latest research findings into easily understandable, practitioner-friendly language in an interactive, engaging format. Other wraparound resources--case studies, information briefs, fundamental skill sheets, video vignettes--allow learners to delve into module topics in more depth.

The Mission of the National Center on Intensive Intervention (NCII) is to build the capacity of state and local education agencies, universities, practitioners, and other stakeholders to support implementation of intensive intervention in literacy, mathematics, and behavior for students with severe and persistent learning and/or behavioral needs, often in the context of their multi-tiered system of support (MTSS) or special education services. NCII’s approach to intensive intervention is data-based individualization (DBI), a research-based process that integrates the systematic use of assessment data, validated interventions, and intensification strategies.
