DELTA, Deaf Education through Listening and Talking, is a voluntary association of young deaf adults, the families and teachers of deaf children. DELTA is a national charity which supports and develops the Natural Aural Approach to the education of deaf children. Both the Approach and the Association trace their origins back to a group of teachers of the deaf working together from 1980 to improve the outcomes for deaf children. The Association exists for the Approach and the Approach exists because of the work of the members of the Association.
