NIMAS refers to a technical standard used to produce XML-based source files. From these well-structured source files, accessible, student-ready alternate-format versions of textbooks and core materials (., Braille, e-text, Digital Talking Book, large print, etc.) can subsequently be created and distributed to qualified students with print disabilities. NIMAS files are not student-ready versions. IDEA 2004, . 108-446, establishes the NIMAS as a national standard and requires states and local districts to adopt the NIMAS for providing textbooks and instructional materials to students who are blind or print-disabled.
