In 1975, Miles left the NTD to work with the campus service for the deaf at California State University, Northridge. She returned to live in England in the autumn of 1977, after twenty years in America. Dot was soon involved in the National Union of the Deaf's Open Door (BBC TV) pioneering television programme (in which she performed her poem Language for the Eye) and was involved in discussions that led to the See Hear television series. She took work with the British Deaf Association, working on various projects. She compiled the first teaching manual for BSL tutors and became involved in setting up the Council for the Advancement of Communication with Deaf People (CACDP). She also worked on the BDA dictionary. For a while she worked as a self-employed writer, lecturer and performer, becoming involved in promotion of sign language teaching and training of tutors and deaf theatre. She was involved in setting up and then teaching on the British Sign Language Tutor Training Course - the first university course for training deaf people to become BSL tutors. She also wrote the best-selling BBC book BSL - A beginner's guide, which was published to complement the television series.
