No, perhaps not, but they are made to test the ability of a dog on a shoot day, the only difference is the level of training, and the fact that they aren't done with live game. The lower end of the scale is great for those who want to dabble, and don't want to have to pick up dead things, the top end is much more competitive.
That's why I can't understand the purpose of having a separate qualification, when tests are already there to make use of. The main difference I can see is that this is not a competition, it's a qualification that the dog gets after being assessed.
There are a couple of interesting articles on the Labrador Retriever Club about this sort of topic, I was interested to read in one, Mary Roslin Smith used to say that the term 'SH CH' stands for 'Shame Champion'. And a very interesting article by Susan Scales.....
