It is best practice to have all videos/films captioned. It is required for students approved for this accommodation, but it is also beneficial to all learners within the course. Many new videos and films are already captioned. Nevertheless, always check to make sure they are indeed captioned AND the captioning is accurate, and you know how to turn on captions should the media be “closed captioned.”
To request closed captions, fill out a Service Hub ticket. There is a tutorial on how to use Service Hub on the IT website.
