TEACCH

Treatment and Education of Autistic and Communication Handicapped Children. I’m not sure why the last C and the H have been swapped round, probably to make a pronounceable word! It must be said that this is a highly effective approach in spite of the strange acronym.

PECS

Picture Exchange Communication System. A communication system where a child learns to exchange a picture for something they want. Very good for children who do not speak or are on the autistic spectrum. It often supports development of spoken language.
