Accessible media producers (AMPs) are authorized entities that produce instructional materials in specialized formats such as braille, large print, audio, or digital text. AMPs may use source files formatted according to the National Instructional Materials Standard (NIMAS) to convert materials into student-ready specialized formats or they may produce materials from a variety of other sources. Materials produced by AMPs are generally available to students and others who meet copyright criteria to receive specialized formats; however, only those students who are dually qualified (meet copyright criteria and are served under IDEA) can receive specialized formats created from NIMAS filesets obtained from the NIMAC.

The AEM Guide to AMPs Summary Table presents an overview of the services provided by each AMP to students who meet copyright criteria for specialized formats. Review the table to determine if the AMP listed provides the types of services needed and use the links to get more detailed information on the AMPs’ web sites. Readers may also want to refer to the separate FAQ documents for each AMP on the AEM Guide to AMPs page. Please note that services listed are those directly provided by the AMP; however, files obtained from the AMP may be converted into other specialized formats using other software and hardware solutions.
