It does, in fact, take years. Go to as many seminars as you can, other breeds as well as your own. The more you learn the better you can put it into practice when stood in the middle of the ring. I think I'm right in saying that the three Kennel Club seminars are compulsary only for judges who want to award CCs (I may be wrong) but try and do them if possible. The conformation and movement one, especially, will be invaluable to you.
Sit and watch respected judges in the ring. See what dogs they put up and try to figure out why. But remember, judging from ringside is very very different from being inside the ring. In the middle of the ring and getting your hands on the dogs, you get a whole different perspective on them.
IMO people should wait at least 5 years before judging if they've just started showing. I know this may seem a long time but the experience and knowledge gained in that time is something you can't learn on paper. There's a lot of judges out there who can pick out a decent dog but they can,t tell you why they think it should win....and IMO that's almost as important as finding the right dog to put up.
There was talk at one time about having student judges who would be in the ring with the main judge, seeing what they did and asking questions about placings etc. but this seemed to have died the death. It would have been a good thing I think, they do it on the continent and (as long as the main judge knows what he/she is doing) experience of thins kind can come in very useful.
When all's said and done though, who judges where and why is all a matter of getting that invite. You can judge 3 classes of any breed (and 5 for some breeds) without being on a judges list at all.
Hope this helps a little,
