I do not know of any courses currently available. I do believe there are some in the works. I would suggest you contact AER or one of the universities that teach braille to teachers. I know the universities have begun to teach it, but I do not know what curriculum they are using. I asked around a bit and could not find out anything else more specific. I will continue to look into this and let you know if I hear of anything. I do know that Hadley School for the Blind has some free courses aimed at teaching UEB to braille readers...but I do not know if that curriculum is available to teachers.
