About the AEM Center


For learners with sensory, physical, cognitive, or learning differences and their teachers, accessible educational materials (AEM) may open doors to teaching and learning that ordinary print-based materials have closed. Accessible educational materials or AEM are specialized formats of curricular content that can be used by and with students who are unable to read or use standard print materials. Specialized formats include braille, audio, large print, and digital text. The Individuals with Disabilities Education Act (IDEA) includes a requirement that schools provide AEM in a timely manner to K–12 students who need them for participation and achievement.

In addition, the AEM Center provides support for the use of AEM in early learning, higher education, and workplace settings and has extended its reach to include educational materials that are first developed and distributed in digital formats. The AEM Center will also provide support for the development, selection, and use of accessible technologies.

AEM Center Leadership

AEM Center Products and Services

The AEM Center serves as a resource for stakeholders, including state- and district-level educators, parents, students, publishers, conversion houses, accessible media producers, and others interested in learning more about AEM and implementing AEM and NIMAS. Our services and activities include the following:

  • Developing and sustaining a readily available base of information and tools to build the capacity of stakeholders to enhance both the effective provision and use of high quality AEM.
  • Providing stakeholders with expert technical assistance and customized "just-in-time" consultation on major issues relevant to the timely provision and use of AEM.
  • Hosting a Community of Practice (COP) that offers a functional connection between State Education Agency Coordinators and AEM Center staff to ensure state and local level implementation and to improve the outcomes of students with disabilities through the timely provision and use of AEM.
  • Collaborating with OSEP, AEM-related OSEP-funded projects work with technical assistance and dissemination center networks, family centers, and post-secondary AEM providers to build capacity for and raise awareness about the timely provision and use of AEM to improve outcomes for learners with print-related disabilities.
  • Providing additional services and products related to Early Learning, Higher Education, and Workforce Development to be announced in the near future.

The AEM Center, with the support of national experts, also maintains and advances the NIMAS Technical Specification used by educational publishers to prepare filesets that are deposited in the National Instructional Materials Accessibility Center (NIMAC) at the American Printing House for the Blind (APH). The Center also promotes the commercial and OER development of accessible EPUB3 so that the markets may play a more significant role in the timely provision of accessible educational materials to learners.
