I can't imagine such a question being asked at interview, to be honest. More like - can you handle a budget - how do you cope with a challenging pupil/class - can we see you teach a lesson on rhythm and pulse - what are your first thoughts on developing music within the school - do you play the piano well enough to accompany Grade VIII entrants - what have you been doing for the last year. Simple, tangible questions with real answers. By-the-way, I have no idea what PLT, AFL and APS stand for! Should I be aware of them as well?
