You say you want a place for a YKC trainee, do you mean a child or specifically a club running under KC? Some clubs are KC linked, some aren't. Agility Addicts is independent, not KC, they have a different grading structure and different height categories for the dogs. There are also BAA (British Agility Association), EMDAC (East Midlands Dog Agility Clubs) and other independent organisations who have their own rules. I think that if the agility part of YKC activities, it would have to be a club using KC rules. The training should cover the same criteria though, and you can compete under any/all of the banners. Until a few years ago, the KC banned people who competed under the other banners.
