SVFR is a validation all of its own - However it is generally lumped in with another validation....usually Thames Radar (London City), although any approach controller is able to add it on to their ticket (not that many choose to do so!!!!)
I believe the way the college course is set up now the options are either Aerodrome, Approach or Area - before the new course was introduced Aerodrome and Approach were taken together giving the student and the company more flexibility as to a posting.... however for LTCC both Area and Approach will get you the possibility of a posting at Swanwick.....
