National Association of the Deaf

American Sign Language



The NAD values deaf and hard of hearing Americans with diverse perspectives, experiences, and abilities. We embrace diversity and inclusiveness as core values in achieving our mission. It is the philosophy of the NAD that diversity encompasses a wide range of human abilities and perspectives. The NAD is committed to building and maintaining an inclusive environment where differences of opinions, beliefs, and values are sought, respected, and valued.

The NAD recognizes that American Sign Language (ASL) is the backbone of the American deaf culture. The NAD values the acquisition, usage and preservation of ASL and is a recognized leader in promoting the acquisition, learning, teaching, and interpreting of ASL. The NAD was created in part to promote and preserve ASL as a legitimate language and an optimal educational tool for deaf children and adults.
