I don't remember it being in the Bronze exam in the UK, and at present that's the only exam we do - EASA looms. The person I brought my glider from showed me (we rigged, fiddled & derigged when I went to see it), I showed my syndicate partner. We also help rig & derig club gliders which where I fly are all modern glass gliders. We always do a positive control check after rigging, and club gliders get one each time they are DI'd.
BTW there are more gliding clubs in Scotland:
The Scottish Gliding Centre Official Website (Portmoak)
Cairngorm Gliding Club - Feshie
Highland Gliding Club (Easterton)
http://www.deesideglidingclub.co.uk/ (Aboyne)
Home Page (Dumfries)
However so far as I know only the first flies 7 days a week, weather permitting.
