National Instructional Materials Access Center (NIMAC)
The National Instructional Materials Access Center (NIMAC) was created under the IDEA law. It serves as a national library for digital source files that help create accessible versions of K–12 textbooks, such as braille, large print, digital text and audiobooks. The NIMAC website lists all files sent by publishers that were requested through school district purchasing contracts.
These files use a special format called NIMAS, which stands for National Instructional Materials Accessibility Standard. Publishers began using this format in 2006.
NIMAS files make it easier and faster to create accessible learning materials. They are source files that must be converted into usable formats, such as braille, large print, digital audio or accessible e-books like DAISY or EPUB. This conversion is done by Accessible Media Producers (AMPs) using special software.
Because NIMAS files are raw and must be converted, they are not available directly to schools or students.
Only students who qualify for this service through an Individualized Education Program (IEP) can receive materials made from NIMAS files. Students with 504 plans do not qualify.
Publishers send NIMAS files to NIMAC only when requested through a purchasing contract with a school district. For this reason, every school district’s contract or purchase order should include a clause that requires publishers to create NIMAS files and send them to NIMAC.
