Did you know that NIMAS files are available for FOSS grades K-8 student print materials? Maybe you’ve heard of NIMAS, but you’re unsure of what it is or how to access the files. Here’s a brief overview of the basics.

What are NIMAS files?
NIMAS is an acronym that stands for “National Instructional Materials Accessibility Standard.” NIMAS files are XML-based source files that can be used to produce alternatives to standard print — braille, large print, digital, and audio books — for students who are blind or have other print disabilities.

NIMAS files are not intended for distribution as is to classrooms, schools, or districts because the xml files require additional enhancements to make them accessible and student-ready. Typically a third party, such as American Printing House for the Blind, a regional/state conversion organization, or braille transcribers, produces the student-ready books required for classroom use.

Where can I find NIMAS files?
NIMAS files are stored in the national repository called NIMAC (National Instructional Materials Accessibility Center) at The NIMAC contains all NIMAS files for a publisher's student print instructional materials. For FOSS, this includes all the NG Edition FOSS Science Stories (grades K-5), all 3rd Edition FOSS Science Stories (grades K-6), 2nd Edition FOSS Science Stories (grades K-6), the California Edition © 2007 FOSS Science Resources books (grades K-5), and the FOSS Middle School Resources books (grades 6-8). In addition, the NIMAC has NIMAS files for all FOSS student duplication masters, lab notebooks, and assessment masters from the Teacher Guides (grades K-8).

The overall purpose of NIMAS and the NIMAC is to have a consistent national standard of high-quality source files available through one central location to improve the quality and delivery of required specialized formats.

How do I search for NIMAS files?
As a teacher, you can search the NIMAC to see what files are available. To do this, simply go to, click “Enter the NIMAC Repository,” and then click “Search the NIMAC.” You can search the NIMAC in a variety of ways—by title, series, author, publisher, edition, ISBN, subject, or grade level.

How do I download and obtain NIMAS files?
You can obtain NIMAS files from your state or local education agency’s authorized user(s). Authorized users are those individuals designated by the state or local education agency to have access to the NIMAC database and are the only ones that can download NIMAS files in accordance with a signed Limitation of Use Agreement.

You can find out who the authorized users in your state are by visiting the following website: Here you will find a comprehensive list of the authorized users organized by state, as well as their telephone number and email address.

One important note: It is not mandated that every state coordinates with the NIMAC. However, states are required to provide instructional materials to blind students or those with other print disabilities in a timely manner. Please check if your state has opted not to coordinate through the NIMAC. For the latest information, you can visit
