Bad interpreters at mainstream college



I know someone that is Deaf and attending a mainstream university. Unfortunately, some of the interpreters he has had while attending that university have been subpar. The agency that the interpreters come from have a contract with the university. The interpreters are from another state, underpaid, and aren't very good, especially for some of these science classes. My Deaf friends needs interpreters that know what they're doing, or else his education will suffer.

Does anyone know what else he can do??
