Reba meant that she isn't deaf. She is an ASL interpreter for the deaf. In the middle and high school classes, students need interpreters, notetakers, extended time for tests, assistance with writing assignments, interpreted instructions for tests, alternate location (as in no distractions) for testing, tutoring services, and I might that terps are needed not just for classes, but for extracurricular activities,meetings such as IEP, etc. And terps should be certified as educational interpreters.
