The International Association for Spelling as Communication (I-ASC) is is an association composed of individuals from the nonspeaking and neurodiverse communities; their families; trained practitioners; and informed allies. I-ASC is committed to ensuring access to effective communication that supports agency and autonomy for nonspeaking, minimally and unreliably speaking individuals.

The mission of I-ASC is to advance communication access for nonspeaking individuals globally through training, education, advocacy, and research. 

I-ASC supports all forms of augmentative and alternative communication (AAC) with a focus on methods of spelling and typing. I-ASC currently offers Practitioner training in Spelling to Communicate (S2C) with the hope that other methods of AAC using spelling or typing will join our association. 

I-ASC is featured in the critically acclaimed documentary The Reason I Jump, which won the Audience award when it premiered at Sundance in January 2020.
