The Office of Special Education and Rehabilitation Services (OSERS) has received communications from stakeholders, including parents, advocacy groups, and national disability organizations, who believe that state and local educational agencies (SEAs and LEAs) are reluctant to reference or use dyslexia, dyscalculia, and dysgraphia in evaluations, eligibility determinations, or in developing the individualized education program (IEP) under the IDEA.
This policy guidance letter clarifies that there is nothing in the IDEA that would prohibit the use of the terms dyslexia, dyscalculia and dysgraphia in IDEA evaluation, eligibility determinations, or IEP documents.
