The IRIS Center is a national center that aims to provide high-quality resources for college and university faculty and professional development providers about students with disabilities. IRIS seeks to obtain this goal by providing free, online, interactive training enhancements that translate research about the education of students with disabilities into practice.

How can educators distinguish between learning disabilities and language difficulties? Historically in the United States, there has been a tendency to refer English language learners (ELLs) inappropriately to special education. This has led to the overidentification of ELLs as having special education needs and a disproportionate representation of ELLs in special education.

The National Research Center on Learning Disabilities (NRCLD) conducts research on the identification of learning disabilities; formulates implementation recommendations; disseminates findings; and provides technical assistance to national, state, and local constituencies.
