Hi, I've recently completed my qualifications with RAD on the CBTS course; its very much independant study and worked for me as opposed to ISTD as I couldnt get to any of the centres which offer it. The only in person requirements are a teaching post for the 2nd year, somewhere local to you, and a 10 day in person course which can be at RAD HQ or sometinmes other venues. This can also be online as they run it for international students, but not always.
