I'm not sure the extent of the accommodations needed, but I know the Acton-Boxborough school system pretty well. Had a classmate for whom the teacher would wear a device that amplified their voice directly into the student's hearing aid, all of us would use it when giving presentations, etc. It was totally chill and uneventful.

We also had a lot of classroom aides and special education resources, though not sure about resources for complete deafness.

Good luck!
