Debbie Debbie, I am wondering what her program is like now. My concern would be the child's language development.
Language is learned by direct communication.
My experience is that children can learn certain signs through the interpreter but as far as language, then based on my training and experience that would be difficult. She still could be mainstreamed with a teacher of the deaf. I would not ask so much for an interpreter with multiple roles, but a language facilitator, that way she or he can do alot more. I don't want to see the role of the interpreter becoming skewed that way. A language facilitator can do alot more in the classroom than a teacher.
