Students who are eligible for AEM:

“‘Eligible person’ means an individual who, regardless of any other disability—

(A) is blind;

(B) has a visual impairment or perceptual or reading disability that cannot be improved to give visual function substantially equivalent to that of a person who has no such impairment or disability and so is unable to read printed works to substantially the same degree as a person without an impairment or disability; or

(C) is otherwise unable, through physical disability, to hold or manipulate a book or to focus or move the eyes to the extent that would be normally acceptable for reading.

The IDEA specifically focuses on accessible formats of printed instructional materials and includes timely provision of accessible formats to students who need them.  The four accessible formats included in IDEA are braille, large print, audio and digital text (aem.cast.org).
