What are accessible instructional materials (AIM)? Answer from www.cast.org "Accessible instructional materials, or AIM, refers to print-based educational materials that are converted into specialized formats (e.g., braille, large print, audio and digital text). As IDEA (the Individuals with Disabilities Education Act) specifically focuses on the provision of accessible formats of print instructional materials, the term AIM is used when referring to accessible materials related to the requirements of the IDEA statute and regulations.”
What are accessible educational materials (AEM) ? Answer from www.cast.org "Accessible educational materials, or AEM, are print- and technology-based educational materials, including printed and electronic textbooks and related core materials that are designed or enhanced in a way that makes them usable across the widest range of learner variability, regardless of format (e.g. print, digital, graphic, audio, video)."
