I take it, then, that you would argue that, as as long as a music teacher can sightread anything put in front of him, it isn't as important that he should be able to give useful guidance on the interpretation of a piece, or to teach improvisation to a jazz pupil, or to transpose an accompaniment for a singer, or for a choir director to hold a tune when singing in parts?
No, I wouldn't argue that. But what I think would be the case is that the majority of issues you mention - interpretation, improvisation, transposition - can be examined and demonstrated in the course of the viva which constitutes the major part of the exam, whereas the quick study (which isn't sight-reading by the way, have a look at some of the threads on the subject to see the difference) can only really be examined by doing it.
As far as a choir director holding a tune goes, I don't see why that should be a particular issue in the
teaching diploma, but if you feel it is something you want to point out, do so in the viva.
