National Instructional Materials Accessibility Standard (NIMAS)

The Individuals with Disabilities Education Act (IDEA) requires school districts to provide instructional materials to blind persons or other persons with print disabilities in a timely manner. This means that districts must take all reasonable steps to provide print instructional materials in accessible formats to children with disabilities at the same time as other children receive those materials.

What is NIMAS?

The National Instructional Materials Accessibility Standard (NIMAS) is a technical standard that curriculum publishers began using in 2006. NIMAS is designed to make it easier and faster to obtain accessible instructional materials. Publishers will send NIMAS files to the National Instructional Materials Access Center (NIMAC), when requested to do so through a purchasing contract with a school district. The NIMAS files can then be used to produce alternate formats, including braille, large print, digital text, and audio books, for students with disabilities.

The NIMAS Center maintains and updates the National Instructional Materials Accessibility Standard (NIMAS), which guides the production of alternate versions of textbooks and related instructional materials.
