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 National Center on Educational Outcomes (NCEO) focuses on the inclusion of students with disabilities, English learners, and English learners with disabilities in instruction and assessments. The scope of NCEO’s work includes issues related to accessibility of assessments across the comprehensive assessment system including formative assessment practices, classroom-based assessments, diagnostic assessments, interim assessments, and summative assessments.

NCEO is a leader in advocating for appropriate testing access and accommodations for students with disabilities, including English learners with disabilities and English learners without disabilities. NCEO works to ensure that the assessment results for these groups of students are reported just as they are for other students and that they influence accountability systems in the same way as they do other students.
