@TheatreMom21, all the UK programs you list are excellent. (Like Juilliard, most of their acceptance rates are less than 1%) However, some of the UK programs don’t accept Americans for their BA degree, for instance Bristol Old Vic. Others rarely accept Americans. Many require a callback in the UK, something you might consider. Most do not include dorms or food; students live in flats and have to be very independent. Also, many don’t accept FAFSA. LAMDA does but others don’t. It’s almost unheard of for Americans to get scholarships, as well. So if finances are an issue, you might take all this into account. Oh one more thing–UK programs (except for a very few) don’t differentiate between MT and straight acting. They do both. Please feel free to pm me with specific questions. 
Since he’s going to several terrific programs during the summer, this may well help him figure out what he wants out of college.
