    About NIMAC

    Created by IDEA 2004, the NIMAC is a federally-funded, searchable online repository of source files for K-12 instructional materials. We receive files in the XML-based NIMAS (National Instructional Materials Accessibility Standard) format, and states use these materials in the production of accessible formats such as braille, large print, and digital text. The NIMAC currently has over 81,000 files from more than 200 publishers.

    For the complete legislative language in IDEA 2004 regarding the NIMAC, visit NIMAS and AIM in IDEA.

    Based on the DAISY standard, NIMAS itself is not intended for distribution directly to students – generally, it requires conversion to become a fully-accessible textbook equivalent for students with print disabilities.



    The Accessible Materials Process:

    Description to follow

    State and local educational agencies, and the accessible media producers they choose, use the NIMAC to download NIMAS files; they then convert the files into accessible materials including braille, digital audio, DAISY text, DAISY audio, large print, or other student-ready formats.

    • Over 160 K-12 educational publishers have submitted files to the NIMAC.
    • More than 70,000 NIMAS files are available in the NIMAC.
    • All 50 states, plus all seven of the eligible outlying areas, have coordinated with the NIMAC.
    • The NIMAC has over 400 registered users.
    • Our online system gives states and media producers 24/7 access to NIMAS source files.
    • NIMAC accounts are available to Authorized Users, Accessible Media Producers, State or Local Education Coordinators, and publishers.

    The NIMAC Advisory Council provides NIMAC with input on policy issues from a broad range of stakeholders.

    Braille & Born Digital Curriculum Survey

    The NIMAC is pleased to share the results of the Braille & Born Digital Curriculum Survey, which was developed and distributed in collaboration with the National AEM Center at CAST and the American Printing House for the Blind (APH). The purpose of this survey was to find out more about the challenges confronted by braille-reading students in K-12 as digital materials are increasingly used in the classroom. Results can be viewed or downloaded here:
