You simply need to understand what the options are. Onsite captioning is where the realtime captioner sits in the classroom next to the student they are servicing. Remote captioning Remote captioning is a logistical setup wherein the instructor is wired to a microphone, audio feed goes out to the realtime captioner at some other location, realtime translation is made, and the English is modemed back to the student s laptop in the classroom. The realtime captioner is never seen, but a lot of equipment needs to be set in place. The ethics of captioning are identical to the ethics of sign language and other interpreters for the disabled.
Confidentiality is primary.
Servicing the client s needs is the focus. The realtime captioner may not be a student in the class. They are there to service a disabled student. All attempts are made not to disrupt the class or interfere with the instructor while providing service. They trust that the interpreter will be accurate and that the interpreter will admit or acknowledge when the situation requires skills, background, or preparation that he or she does not have.
